#Nmap Changelog ($Id$); -*-text-*-

o [GH#1451] Nmap now performs forward DNS lookups in parallel, using the same

engine that has been reliably performing reverse-DNS lookups for nearly a

decade. Scanning large lists of hostnames is now enormously faster and avoids

the unresponsive wait for blocking system calls, so progress stats can be

shown. In testing, resolving 1 million website names to both IPv4 and IPv6

took just over an hour. The previous system took 49 hours for the same data

set! [Daniel Miller]

Nmap 7.95 [2024-04-23]

o Integrated over 4,000 of your IPv4 OS fingerprints. Added 336 signatures,

bringing the new total to 6,036. Additions include iOS 15 & 16, macOS

Ventura & Monterey, Linux 6.1, OpenBSD 7.1, and lwIP 2.2

o Integrated over 2,500 service/version detection fingerprints. The signature

count went up 1.4% to 12,089, including 9 new softmatches. We now detect

1,246 protocols, including new additions of grpc, mysqlx, essnet,

remotemouse, and tuya.

o [Windows] Upgraded Npcap (our Windows raw packet capturing and transmission

driver) from version 1.75 to the latest version 1.79. It includes many

performance improvements, bug fixes and feature enhancements described at

https://npcap.com/changelog.

o [NSE] Added four new scripts from the DINA community

(https://github.com/DINA-community) for querying industrial control

systems:

+ hartip-info reads device information from devices using the Highway

Addressable Remote Transducer protocol

+ iec61850-mms queries devices using Manufacturing Message Specification

requests. [Dennis Rösch, Max Helbig]

+ multicast-profinet-discovery Sends a multicast PROFINET DCP Identify All

message and prints the responses. [Stefan Eiwanger, DINA-community]

+ profinet-cm-lookup queries the DCERPC endpoint mapper exposed via the

PNIO-CM service.

o Improvements to OS detection fingerprint matching, including a syntax

change for nmap-os-db that allows ranges within the TCP Options

string. This leads to more concise and maintainable fingerprints. [Daniel

Miller]

o Improved the OS detection engine by using a new source port for each retry.

Scans from systems such as Windows that do not send RST for unsolicited

SYN|ACK responses were previously unable to get a response in subsequent

tries. [Daniel Miller]

o Several profile-guided optimizations of the port scan engine. [Daniel Miller]

o Upgraded included libraries: Lua 5.4.6, libpcre2 10.43, zlib 1.3.1, libssh2

1.11.0, liblinear 2.47

o [GH#2639] Upgraded OpenSSL binaries (for the Windows builds and for RPMs)

to version 3.0.13. This addresses various OpenSSL vulnerabilities which

don't impact Nmap (full details are in the GH issue).

o [GH#2672] Fixed an issue where TCP Connect scan (-sT) on Windows would fail

to open any sockets, leading to scans that never finish. [Daniel Miller]

o [Zenmap][Ndiff][GH#2649] Zenmap and Ndiff now use setuptools, not distutils

for packaging.

o [Ncat][GH#2685] Fixed Ncat UDP server mode to not quit after EOF on

stdin. Reported as Debian bug:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1039613

o [NSE] ssh-auth-methods will now print the pre-authentication banner text

when available. Requires libssh2 1.11.0 or later. [Daniel Miller]

o [Zenmap][GH#2739] Fix a crash in Zenmap when changing a host comment.

o [NSE][GH#2766] Fix TLS 1.2 signature algorithms for EdDSA. [Daniel Roethlisberger]

o [Zenmap][GH#2706] RPM spec files now correctly require the python3 package, not python>=3

o [GH#2731] Fix an out-of-bounds read which led to out-of-memory errors when

duplicate addresses were used with --exclude

o [GH#2609] Fixed a memory leak in Nsock: compiled pcap filters were not freed.

o [GH#2658] Fixed a crash when using service name wildcards with -p, as in -p "http*"

o [NSE] Fixed DNS TXT record parsing bug which caused asn-query to fail in

Nmap 7.80 and later. [David Fifield, Mike Pattrick]

o [NSE][GH#2727][GH#2728] Fixed packet size testing in KNX scripts [f0rw4rd]

Nmap 7.94 [2023-05-19]

o Zenmap and Ndiff now use Python 3! Thanks to the many contributors who made

this effort possible:

+ [GH#2088][GH#1176][Zenmap] Updated Zenmap to Python 3 and PyGObject. [Jakub Kulík]

+ [GH#1807][GH#1176][Ndiff] Updated Ndiff to Python 3. [Brian Quigley]

+ Additional Python 3 update fixes by Sam James, Daniel Miller. Special thanks

to those who opened Python 3-related issues and pull requests: Eli

Schwartz, Romain Leonard, Varunram Ganesh, Pavel Zhukov, Carey Balboa,

Hasan Aliyev, and others.

o [Windows] Upgraded Npcap (our Windows raw packet capturing and

transmission driver) from version 1.71 to the latest version 1.75. It

includes dozens of performance improvements, bug fixes and feature

enhancements described at https://npcap.com/changelog.

o Nmap now prints vendor names based on MAC address for MA-S (24-bit), MA-M

(28-bit), and MA-L (36-bit) registrations instead of the fixed 3-byte MAC

prefix used previously for lookups.

o Added partial silent-install support to the Nmap Windows

installer. It previously didn't offer silent mode (/S) because the

free/demo version of Npcap Windoes packet capturing driver that it

needs and ships with doesn't include a silent installer. Now with

the /S option, Nmap checks whether Npcap is already installed

(either the free version or OEM) and will silently install itself if

so. This is similar to how the Wireshark installer works and is

particularly helpful for organizations that want to fully automate

their Nmap (and Npcap) deployments. See

https://nmap.org/nmap-silent-install for more details.

o Lots of profile-guided memory and processing improvements for Nmap, including

OS fingerprint matching, probe matching and retransmission lookups for large

hostgroups, and service name lookups. Overhauled Nmap's string interning and

several other startup-related procedures to speed up start times, especially

for scans using OS detection. [Daniel Miller]

o Integrated many of the most-submitted IPv4 OS fingerprints for recent

versions of Windows, iOS, macOS, Linux, and BSD. Added 22 fingerprints,

bringing the new total to 5700!

o [NSE][GH#548] Added the tftp-version script which requests a

nonexistent file from a TFTP server and matches the error message

to a database of known software. [Mak Kolybabi]

o [Ncat][GH#1223] Ncat can now accept "connections" from multiple UDP hosts in

listen mode with the --keep-open option. This also enables --broker and

--chat via UDP. [Daniel Miller]

o [GH#2575] Upgraded OpenSSL binaries (for the Windows builds and for

RPM's) to version 3.0.8. This resolves some CVE's (CVE-2022-3602;

CVE-2022-3786) which don't impact Nmap proper since it doesn't do

certificate validation, but could possibly impact Ncat when the

--ssl-verify option is used.

o Upgrade included libraries: zlib 1.2.13, Lua 5.4.4, libpcap 1.10.4

o [GH#2532] Removed the bogus OpenSSL message from the Windows Nmap

executable which looked like "NSOCK ERROR ssl_init_helper(): OpenSSL

legacy provider failed to load." We actually already have the legacy

provider built-in to our OpenSSL builds, and that's why loading the

external one fails.

o [GH#2541] UDP port scan (-sU) and version scan (-sV) now both use the same

data source, nmap-service-probes, for data payloads. Previously, the

nmap-payloads file was used for port scan. Port scan responses will be used

to kick-start the version matching process. [Daniel Miller]

o Nmap's service scan (-sV) can now probe the UDP service behind a DTLS tunnel,

the same as it already does for TCP services with SSL/TLS encryption. The

DTLSSessionReq probe has had its rarity lowered to 2 to allow it to be sent

sooner in the scan. [Daniel Miller]

o [Ncat] Ncat in listen mode with --udp --ssl will use DTLS to secure incoming

connections. [Daniel Miller]

o [GH#1023] Handle Internationalized Domain Names (IDN) like Яндекс.рф on

platforms where getaddrinfo supports the AI_IDN flag. [Daniel Miller]

o [Ncat] Addressed an issue from the Debian bug tracker

(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=969314) regarding data

received immediately after a SOCKS CONNECT response. Ncat can now be

correctly used in the ProxyCommand option of OpenSSH.

o Improved DNS domain name parsing to avoid recursion and enforce name length

limits, avoiding a theoretical stack overflow issue with certain crafted DNS

server responses, reported by Philippe Antoine.

o [GH#2338][NSE] Fix mpint packing in ssh2 library, which was causing OpenSSH

errors like "ssh_dispatch_run_fatal: bignum is negative" [Sami Loone]

o [GH#2507] Updates to the Japanese manpage translation by Taichi Kotake.

o [Ncat][GH#1026][GH#2426] Dramatically speed up Ncat transfers on

Windows by avoiding a 125ms wait for every read from

STDIN. [scriptjunkie]

o [GH#1192][Windows] Periodically reset the system idle timer to keep the

system from going to sleep while scans are in process. This only affects port

scans and OS detection scans, since NSE and version scan do not rely on

timing data to adjust speed.

o Updated the Nmap Public Source License (NPSL) to Version 0.95. This

just clarifies that the derivative works definition and all other

license clauses only apply to parties who choose to accept the

license in return for the special rights granted (such as Nmap

redistribution rights). If a party can do everything they need to

using copyright provisions outside of this license such as fair use,

we support that and aren't trying to claim any control over their

work. Versions of Nmap released under previous versions of the NPSL

may also be used under the NPSL 0.95 terms.

o Avoid storing many small strings from IPv4 OS detection results in the global

string_pool. These were effectively leaked after a host is done being

scanned, since string_pool allocations are not freed until Nmap quits.

Nmap 7.93 [2022-09-01]

o This release commemorates Nmap's 25th anniversary! It all started with this

September 1, 1997 Phrack article by Fyodor: https://nmap.org/p51-11.html.

o [Windows] Upgraded Npcap (our Windows raw packet capturing and

transmission driver) from version 1.50 to the latest version 1.71. It

includes dozens of performance improvements, bug fixes and feature

enhancements described at https://npcap.com/changelog.

o Ensure Nmap builds with OpenSSL 3.0 using no deprecated API functions.

Binaries for this release include OpenSSL 3.0.5.

o Upgrade included libraries: libssh2 1.10.0, zlib 1.2.12, Lua 5.3.6, libpcap 1.10.1

o [GH#2416] Fix a bug that prevented Nmap from discovering interfaces on Linux

when no IPv4 addresses were configured. [Daniel Miller, nnposter]

o [NSE][GH#2463] NSE "exception handling" with nmap.new_try() will no longer

result in a stack traceback in debug output nor a "ERROR: script execution

failed" message in script output, since the intended behavior has always been

to end the script immediately without output. [Daniel Miller]

o [GH#2494] Update the Nmap output DTD to match actual output since the

`<hosthint>` element was added in Nmap 7.90.

o [NSE][GH#2496] Fix newtargets support: since Nmap 7.92, scripts could not add

targets in script pre-scanning phase. [Daniel Miller]

o [GH#2468] Scripts dhcp-discover and broadcast-dhcp-discover now support

setting a client identifier. [nnposter]

o [GH#2331][GH#2471] Script oracle-tns-version was not reporting the version

correctly for Oracle 19c or newer [linholmes]

o [GH#2296][GH#2342] Script redis-info was crashing or producing inaccurate

information about client connections and/or cluster nodes. [nnposter]

o [GH#2379] Nmap and Nping were unable to obtain system routes on FreeBSD

[benpratt, nnposter]

o [GH#2464] Script ipidseq was broken due to calling an unreachable library

function. [nnposter]

o [GH#2420][GH#2436] Support for EC crypto was not properly enabled if Nmap

was compiled with OpenSSL in a custom location. [nnposter]

o [NSE] Improvements to event handling and pcap socket garbage collection,

fixing potential hangs and crashes. [Daniel Miller]

o We ceased creating the Nmap win32 binary zipfile. It was useful back when

you could just unzip it and run Nmap from there, but that hasn't worked well

for many years. The win32 self-installer handles Npcap installation and many

other dependencies and complexities. Anyone who needs the binaries for some

reason can still install Nmap on any system and retrieve them from there.

For now we're keeping the Win32 zipfile in the Nmap OEM Edition

(https://nmap.org/oem) for companies building Nmap into their own

products. But even in that case we believe that running the Nmap OEM

self-installer in silent mode is a better approach.

o [GH#2388] Fix TDS7 password encoding for mssql.lua, which had been assuming

ASCII input even though other parts of the library had been passing it Unicode.

o [GH#2402] Replace deprecated CPEs for IIS with their updated identifier,

cpe:/a:microsoft:internet_information_services [Esa Jokinen]

o [NSE][GH#2393] Fix script-terminating error when unknown BSON data types are

encountered. Added parsers for most standard data types. [Daniel Miller]

o [Ncat] Fix hostname/certificate comparison and matching to handle ASN.1

strings without null terminators, a similar bug to OpenSSL's CVE-2021-3712.

o [Ncat][GH#2365] Added support for SOCKS5 proxies that return bind addresses

as hostnames, instead of IPv4/IPv6 addresses. [pomu0325]

Nmap 7.92 [2021-08-07]

o [Windows] Upgraded Npcap (our Windows raw packet capturing and

transmission driver) from version 1.00 to the latest version 1.50. You can

read about the dozens of performance improvements, bug fixes and feature

enhancements at https://npcap.com/changelog.

o [Windows] Thanks to the Npcap 1.50 upgrade, Nmap now works on the Windows

ARM architecture so you can run it on lightweight and power-efficient

tablets like the Microsoft Surface Pro X and Samsung Galaxy Book Go. More

ARM devices are on the way along with the upcoming Windows 11 release. See

the Npcap on ARM announcement at

https://seclists.org/nmap-announce/2021/2.

o [Windows] Updated our Windows builds to Visual Studio 2019, Windows 10

SDK, and the UCRT. This prevents Nmap from working on Windows Vista and

earlier, but they can still use older versions of Nmap on their ancient

operating system.

o New Nmap option --unique will prevent Nmap from scanning the same IP

address twice, which can happen when different names resolve to the same

address. [Daniel Miller]

o [NSE][GH#1691] TLS 1.3 now supported by most scripts for which it is

relevant, such as ssl-enum-ciphers. Some functions like ssl tunnel

connections and certificate parsing will require OpenSSL 1.1.1 or later to

fully support TLS 1.3. [Daniel Miller]

o [NSE] Added 3 NSE scripts, from 4 authors, bringing the total up to 604!

They are all listed at https://nmap.org/nsedoc/, and the summaries are

below:

+ [GH#2201] nbns-interfaces queries NetBIOS name service (NBNS) to gather

IP addresses of the target's network interfaces [Andrey Zhukov]

+ [GH#711] openflow-info gathers preferred and supported protocol versions

from OpenFlow devices [Jay Smith, Mak Kolybabi]

+ port-states prints a list of ports that were found in each state,

including states that were summarized as "Not shown: X closed ports"

[Daniel Miller]

o Several changes to UDP payloads to improve accuracy:

+ [GH#2269] Fix an issue with -sU where payload data went out-of-scope

before it was used, causing corrupted payloads to be sent. [Mariusz

Ziulek]

+ Nmap's retransmission limits were preventing some UDP payloads from

being tried with -sU and -PU. Now, Nmap sends each payload for a

particular port at the same time without delay. [Daniel Miller]

+ New UDP payloads:

- [GH#1279] TS3INIT1 for UDP 3389 [colcrunch]

- [GH#1895] DTLS for UDP 3391 (RD Gateway) [Arnim Rupp]

o [NSE][GH#2208][GH#2203] SMB2 dialect handling has been

redesigned. Visible changes include:

* Notable improvement in speed of script smb-protocols and others

* Some SMB scripts are no longer using a hardcoded dialect, improving

target interoperability

* Dialect names are aligned with Microsoft, such as 3.0.2, instead of

3.02 [nnposter]

o [GH#2350] Upgraded OpenSSL to version 1.1.1k. This addresses some

CVE's which don't affect Nmap in a material way. Details:

https://github.com/nmap/nmap/issues/2350

o Removed support for the ancient WinPcap library since we already include

our own Npcap library (https://npcap.com) supporting the same API. WinPcap

was abandoned years ago and it's official download page says that "WE

RECOMMEND USING Npcap INSTEAD" for security, stability, compatibility, and

support reasons.

o [GH#2257] Fix an issue in addrset matching that was causing all targets to

be excluded if the --excludefile listed a CIDR range that contains an

earlier, smaller CIDR range. [Daniel Miller]

o [GH#1922] Fix an issue that would cause Nmap to hang during scans

with a host timeout, such as -T5. Any active probes when a target timed out

were counting towards the global congestion window.

o [GH#2153] Do not count host discovery phase time against the host timeout,

since Nmap may wait a long time between sending probes to a target while it

processes other targets instead.

o [GH#2153] Fix issues with matching ICMP Time Exceeded messages that led to

ignored responses and long scan times when scanning distant targets.

o Upgrade the Windows NSIS installer to use the latest NSIS 3 (version

3.07) instead of the previous NSIS 2 generation.

o Setting --host-timeout=0 will disable the host timeout, which is set by

-T5 to 15 minutes. Earlier versions of Nmap require the user to specify a

very long timeout instead.

o Improvements to Nmap's XML output:

+ If a host times out, the XML <host> element will have the attribute

timedout="true" and the host's timing info (srtt etc.) will still be

printed.

+ The "extrareasons" element now includes a list of port numbers for each

"ignored" state. The "All X ports" and "Not shown:" lines in normal

output have been changed slightly to provide more detail. [Daniel

Miller]

o [NSE][GH#2237] Prevent the ssl-* NSE scripts from probing ports that were

excluded from version scan, usually 9100-9107, since JetDirect will print

anything sent to these ports. [Daniel Miller]

o [GH#2206] Nmap no longer produces cryptic message "Failed to convert

source address to presentation format" when unable to find useable route

to the target. [nnposter]

o [Ncat][GH#2202] Use safety-checked versions of FD_* macros to abort early

if number of connections exceeds FD_SETSIZE. [Pavel Zhukov]

o [Ncat] Connections proxied via SOCKS4/SOCKS5 were intermittently dropping

server data sent right after the connection got established, such as port

banners. [Sami Pönkänen]

o [Ncat][GH#2149] Fixed a bug in proxy connect mode which would close the

connection as soon as it was opened in Nmap 7.90 and 7.91.

o [NSE][GH#2175] Fixed NSE so it will not consolidate all port script output

for targets which share an IP (e.g. HTTP vhosts) under one target. [Daniel

Miller]

o [Zenmap][GH#2157] Fixed an issue where a failure to execute Nmap would

result in a Zenmap crash with "TypeError: coercing to Unicode" exception.

o Nmap no longer considers an ICMP Host Unreachable as confirmation that a

target is down, in accordance with RFC 1122 which says these errors may be

transient. Instead, the probe will be destroyed and other probes used to

determine aliveness. [Daniel Miller]

o [Ncat][GH#2154] Ncat no longer crashes when used with Unix domain sockets.

o [Ncat][GH#2167][GH#2168] Ncat is now again generating certificates with

the duration of one year. Due to a bug, recent versions of Ncat were using

only one minute. [Tobias Girstmair]

o [NSE][GH#2281] URL/percent-encoding is now using uppercase hex digits to

align with RFC 3986, section 2.1, and to improve compatibility with some

real-world web servers. [nnposter]

o [NSE][GH#2174] Script hostmap-crtsh got improved in several ways. The most

visible are that certificate SANs are properly split apart and that

identities that are syntactically incorrect to be hostnames are now

ignored. [Michel Le Bihan, nnposter]

o [NSE] Loading of a Nikto database failed if the file was referenced

relative to the Nmap directory [nnposter]

o We're no longer building and distributing 32-bit Linux binary RPMs since

the vast majority of users are on x64 systems now. Nmap still works on

32-bit systems and so users can build it themselves from the source

RPMs or tarball, or obtain it from their distribution's repository.

o [GH#2199] Updated Nmap's NPSL license to rewrite a poorly-worded clause

about "proprietary software companies". The new license version 0.93 is

still available from https://nmap.org/npsl/. As described on that page, we

are also still offering Nmap 7.90, 7.91, and 7.92 under the previous Nmap

7.80 license. Finally, we still offer the Nmap OEM program for companies

who want a non-copyleft license allowing them to redistribute Nmap with

their products at https://nmap.org/oem/.

o [NSE] Script smb2-vuln-uptime no longer reports false positives when the

target does not provide its boot time. [nnposter]

o [NSE][GH#2197] Client packets composed by the DHCP library will now

contain option 51 (IP address lease time) only when requested. [nnposter]

o [NSE][GH#2192] XML decoding in library citrixxml no longer crashes when

encountering a character reference with codepoint greater than 255. (These

references are now left unmodified.) [nnposter]

o [NSE] Script mysql-audit now defaults to the bundled mysql-cis.audit for

the audit rule base. [nnposter]

o [NSE][GH#1473] It is now possible to control whether the SNMP library uses

v1 (default) or v2c by setting script argument snmp.version. [nnposter]

Nmap 7.91 [2020-10-09]

o [NSE][GH#2136][GH#2137] Fix several places where Lua's os.time was being used

to represent dates prior to January 1, 1970, which fails on Windows. Notably,

NSE refused to run in UTC+X timezones with the error "time result cannot be

represented in this installation" [Clément Notin, nnposter, Daniel Miller]

o [GH#2148][Zenmap] Fix a crash in the profile editor due to a missing import.

o [GH#2139][Nsock][Windows] Demote the IOCP Nsock engine because of some known

issues that will take longer to resolve. The previous default "poll" engine

will be used instead.

o [GH#2140][Nsock][Windows] Fix a crash in service scan due to a previously-unknown

error being returned from the IOCP Nsock engine. [Daniel Miller]

o [NSE][GH#2128] MySQL library was not properly parsing server responses,

resulting in script crashes. [nnposter]

o [GH#2135] Silence the irrelevant warning, "Your ports include 'T:' but you

haven't specified any TCP scan type" when running nmap -sUV

Nmap 7.90 [2020-10-03]

o [Windows] Upgraded Npcap, our Windows packet capturing (and sending)

library to the milestone 1.00 release! It's the culmination of 7 years of

development with 170 public pre-releases. This includes dozens of

performance improvements, bug fixes, and feature enhancements described

at https://npcap.com/changelog.

o Integrated over 800 service/version detection fingerprints submitted since

August 2017. The signature count went up 1.8% to 11,878, including 17 new

softmatches. We now detect 1237 protocols from airmedia-audio, banner-ivu,

and control-m to insteon-plm, pi-hole-stats, and ums-webviewer. A

significant number of submissions remain to be integrated in the next

release.

o Integrated over 330 of the most-frequently-submitted IPv4 OS fingerprints

since August 2017. Added 26 fingerprints, bringing the new total to 5,678.

Additions include iOS 12 & 13, macOS Catalina & Mojave, Linux 5.4, FreeBSD

13, and more.

o Integrated all 67 of your IPv6 OS fingerprint submissions from August 2017 to

September 2020. Added new groups for FreeBSD 12, Linux 5.4, and Windows 10,

and consolidated several weak groups to improve classification accuracy.

o [NSE] Added 3 NSE scripts, from 2 authors, bringing the total up to 601!

They are all listed at https://nmap.org/nsedoc/, and the summaries are

below:

+ dicom-brute attempts to brute force the called Application Entity Title

of DICOM servers. [Paulino Calderon]

+ dicom-ping discovers DICOM servers and determines if any Application

Entity Title is allowed to connect. [Paulino Calderon]

+ uptime-agent-info collects system information from an Idera Uptime

Infrastructure Monitor agent. [Daniel Miller]

o [GH#1834] Addressed over 250 code quality issues identified by LGTM.com,

improving our code quality score from "C" to "A+"

o Released Npcap OEM Edition. For more than 20 years, the Nmap Project has

been funded by selling licenses for companies to distribute Nmap with

their products, along with commercial support. Hundreds of commercial

products now use Nmap for network discovery tasks like port scanning,

host discovery, OS detection, service/version detection, and of course

the Nmap Scripting Engine (NSE). Until now they have just used standard

Nmap, but this new OEM Edition is customized for use within other Windows

software. Nmap OEM contains the OEM version of our Npcap driver, which

allows for silent installation. It also removes the Zenmap GUI, which

cuts the installer size by more than half. And it reports itself as Nmap

OEM so customers know it's a properly licensed Nmap. See

https://nmap.org/oem for more details. We will be reaching out to all

existing licensees with Nmap OEM access credentials, but any licensees

who wants it quicker should see https://nmap.org/oem.

o Upgraded the Nmap license form a sort of hacked-up version of GPLv2 to a

cleaner and better organized version (still based on GPLv2) now called the

Nmap Public Source License to avoid confusion. See https://nmap.org/npsl/

for more details and annotated license text. This NPSL project was started

in 2006 (community discussion here:

https://seclists.org/nmap-dev/2006/q4/126) and then it lost momentum for 7

years until it was restarted in 2013

(https://seclists.org/nmap-dev/2013/q1/399) and then we got distracted by

development again. We still have some ideas for improving the NPSL, but

it's already much better than the current license, so we're applying NPSL

Version 0.92 to the code now and can make improvements later if

needed. This does not change the license of previous Nmap releases.

o Removed nmap-update. This program was intended to provide a way to update

data files and NSE scripts, but the infrastructure was never fielded. It

depended on Subversion version control and would have required maintaining

separate versions of NSE scripts for compatibility.

o Removed the silent-install command-line option (/S) from the Windows

installer. It causes several problems and there were no objections when we

proposed removing it in 2016 (https://seclists.org/nmap-dev/2016/q4/168).

It will remain in Nmap OEM since its main use was for customers who

redistribute Nmap with other software. If anyone else has a strong need

for an Nmap silent installer, please contact sales@nmap.com and we'll see

what we can do.

o [GH#1860] 23 new UDP payloads and dozens more default ports for existing

payloads developed for Rapid7's InsightVM scan engine. These speed up and

ensure detection of open UDP services. [Paul Miseiko, Rapid7]

o [GH#2051] Restrict Nmap's search path for scripts and data files.

NMAPDATADIR, defined on Unix and Linux as ${prefix}/share/nmap, will not be

searched on Windows, where it was previously defined as C:\Nmap .

Additionally, the --script option will not interpret names as directory names

unless they are followed by a '/'. [Daniel Miller]

o [GH#1764] Fix an assertion failure when unsolicited ARP response is received:

nmap: Target.cc:503: void Target::stopTimeOutClock(const timeval*): Assertion `htn.toclock_running == true' failed.

o [NSE] New outlib library consolidates functions related to NSE output,

both string formatting conventions and structured output. [Daniel Miller]

o [NSE] New dicom library implements the DICOM protocol used for

storing and transfering medical images. [Paulino Calderon]

o [GH#92] Fix a regression in ARP host discovery left over from the move from

massping to ultra_scan in Nmap 4.22SOC8 (2007) that sometimes resulted in

missing ARP responses from targets near the end of a scan. Accuracy and speed

are both improved. [Daniel Miller]

o [GH#2126] Fix the "iocp" Nsock engine for Windows to be able to correctly

handle PCAP read events. This engine is now the default for Windows, which

should greatly improve performance over the previous default, the "poll"

engine. [Daniel Miller]

o [GH#2050] Reduced CPU usage of OS scan by 50% by avoiding string copy

operations and removing undocumented fingerprint syntax unused in nmap-os-db

('&' and '+' in expressions). [Daniel Miller]

o [GH#1859] Allow multiple UDP payloads to be specified for a port in

nmap-payloads. If the first payload does not get a response, the remaining

payloads are tried round-robin. [Paul Miseiko, Rapid7]

o [GH#1616] New option --discovery-ignore-rst tells Nmap to ignore TCP RST

responses when determining if a target is up. Useful when firewalls are

spoofing RST packets. [Tom Sellers, Rapid7]

o [Ncat][GH#2087][GH#1927][GH#1928][GH#1974] It is now possible to override

the value of TLS SNI via --ssl-servername [Hank Leininger, nnposter]

o [GH#2104] Fixed parsing of TCP options which would hang (infinite loop) if an

option had an explicit length of 0. Affects Nmap 7.80 only.

[Daniel Miller, Imed Mnif]

o Added a UDP payload for STUN (Session Traversal Utilities for NAT).

[David Fifield]

o [NSE] Fixed an off-by-one bug in the stun.lua library that prevented

parsing a server response. [David Fifield]

o [NSE][GH#1460] Script ssh2-enum-algos would fail if the server initiated

the key exchange before completing the protocol version exchange

[Scott Ellis, nnposter]

o [NSE][GH#2105] Fetching of SSH2 keys might fail because of key exchange

confusion [nnposter]

o [NSE][GH#2098] Performance of script afp-ls has been dramatically improved

[nnposter]

o [NSE][GH#2091] Parsing of AFP FPGetFileDirParms and

simple reflection of HTTP request data [Anders Kaseorg]

o [NSE][GH#1473] SNMP scripts are now enabled on non-standard ports where SNMP

has been detected [usd-markus, nnposter]

o [NSE][GH#2084] MQTT library was using incorrect position when parsing

received responses [tatulea]

o [NSE][GH#2086] IPMI library was using incorrect position when parsing

received responses [Star Salzman]

o [NSE][GH#2086] Scripts ipmi-brute and deluge-rpc-brute were not capturing

successfully brute-forced credentials [Star Salzman]

o Allow resuming IPv6 scans with --resume. The address parsing was assuming IPv4

addresses, leading to "Unable to parse ip" error. In a related fix, MAC addresses

will not be parsed as IP addresses when resuming from XML. [Daniel Miller]

o [GH#1622][GH#2068] Fix reverse-DNS handling of PTR records that are not lowercase.

Nmap was failing to identify reverse-DNS names when the DNS server delivered

them like ".IN-ADDR.ARPA". [Lucas Nussbaum, Richard Schütz, Daniel Miller]

o [NSE][GH#1999][GH#2005] IKE library was not properly populating the protocol

number in aggressive mode requests. [luc-x41]

o [GH#1963] Added service fingerprinting for MySQL 8.x, Microsoft SQL

Server 2019, MariaDB, and Crate.io CrateDB. Updated PostreSQL coverage and

added specific detection of recent versions running in Docker. [Tom Sellers]

o New XML output "hosthint" tag emitted during host discovery when a target is

found to be up. This gives earlier notification than waiting for the

hostgroup to finish all scan phases. [Paul Miseiko]

o [GH#917] New UDP payloads for GPRS Tunneling Protocol (GTP) on ports 2123,

2152, and 3386. [Guillaume Teissier]

o [NSE][GH#1825] SSH scripts now run on several ports likely to be SSH based on

empirical data from Shodan.io, as well as the netconf-ssh service.

[Lim Shi Min Jonathan, Daniel Miller]

o [Zenmap][GH#1777] Stop creating a debugging output file 'tmp.txt' on the

desktop in macOS. [Roland Linder]

o [Nping] Address build failure under libc++ due to "using namespace std;" in

several headers, resulting in conflicting definitions of bind(). Reported by

StormBytePP and Rosen Penev. [Daniel Miller]

o [Ncat][GH#1868] Fix a fatal error when connecting to a Linux VM socket with

verbose output enabled. [Stefano Garzarella]

o [Ncat][GH#2060] Proxy credentials can be alternatively passed onto Ncat by

setting environment variable NCAT_PROXY_AUTH, which reduces the risk of the

credentials getting captured in process logs. [nnposter]

o [NSE][GH#1723] Fixed a crash on Windows when processing a GZIP-encoded HTTP

body. [Daniel Miller]

o Upgrade libpcap to 1.9.1, which addresses several CVE vulnerabilities.

o Upgrade libssh2 to 1.9.0, fixing compilation with OpenSSL 1.1.0 API.

o [GH#1717][GH#1718] Processing of IP address CIDR blocks was not working

correctly on ppc64, ppc64le, and s390x architectures. [rfrohl, nnposter]

o [Windows] Add support for the new loopback behavior in Npcap 0.9983 and

later. This enables Nmap to scan localhost on Windows without needing the

Npcap Loopback Adapter to be installed, which was a source of problems for

some users. [Daniel Miller]

o [NSE] MS SQL library has improved version resolution, from service pack level

to individual cumulative updates [nnposter]

o [NSE][GH#2077] With increased verbosity, script http-default-accounts now

reports matched target fingerprints even if no default credentials were found

[nnposter]

correctly [nnposter]

o [NSE][GH#2063] IPP response parser was not correctly processing

end-of-attributes-tag [nnposter]

o [NSE] Script cups-info was failing due to erroneous double-decoding

of the IPP printer status [nnposter]

o [NSE][GH#2010] Oracle TNS parser was incorrectly unmarshalling DALC byte

arrays [nnposter]

o [NSE] The password hashing function for Oracle 10g was not working correctly

for non-alphanumeric characters [nnposter]

o [NSE] Virtual host probing list, vhosts-full.lst, was missing numerous

entries present in vhosts-default.lst [nnposter]

o [NSE][GH#1931][GH#1932] Script http-grep was not correctly calculating Luhn

checksum [Colleen Li, nnposter]

new argument "mac" to force a specific client MAC address [nnposter]

o [NSE] Code improvements in RPC Dump, benefitting NFS-related scripts

[nnposter]

o [NSE] RPC code was using incorrect port range, which was causing some calls,

such as NFS mountd, to fail intermittently [nnposter]

o [NSE][GH#1876] XML output from script ssl-cert now includes RSA key modulus

and exponent [nnposter]

o [NSE][GH#1837] Nmap no longer crashes when SMB scripts, such as smb-ls, call

smb.find_files [nnposter]

o [NSE][GH#1802] The MongoDB library was causing errors when assembling protocol

payloads. [nnposter]

o [NSE][GH#1781][GH#1796] The RTSP library was not correctly generating request

strings. [nnposter]

error. [nnposter]

o [NSE][GH#1720] Function marshall_dom_sid2 in library msrpctypes was not

correctly populating ID Authority. [nnposter]

o [NSE][GH#1720] Unmarshalling functions in library msrpctypes were attempting

arithmetic on a nil argument. [Ivan Ivanov, nnposter]

o [NSE][GH#1720] Functions lsa_lookupnames2 and lsa_lookupsids2 in library

msrpc were incorrectly referencing function strjoin when called with debug

level 2 or higher. [Ivan Ivanov]

o [NSE][GH#1755][GH#2096] Added HTTP default account fingerprints for Tomcat

Host Manager and Dell iDRAC9. [Clément Notin]

o [NSE][GH#1476][GH#1707] A MS-SMB spec non-compliance in Samba was causing

protocol negotiation to fail with data string too short error.

[Clément Notin, nnposter]

o [NSE][GH#1480][GH#1713][GH#1714] A bug in SMB library was causing scripts to

fail with bad format argument error. [Ivan Ivanov]

authentication but the server does not provide the necessary authentication

header. [nnposter]

o [NSE] Fixed a bug in http-wordpress-users.nse that could cause

extraneous output to be captured as part of a username. [Duarte Silva]

Nmap 7.80 [2019-08-10]

o [Windows] The Npcap Windows packet capturing library (https://npcap.com/)

is faster and more stable than ever. Nmap 7.80 updates the bundled Npcap

from version 0.99-r2 to 0.9982, including all of these changes from the

last 15 Npcap releases: https://npcap.com/changelog

o [NSE] Added 11 NSE scripts, from 8 authors, bringing the total up to 598!

They are all listed at https://nmap.org/nsedoc/, and the summaries are

below:

+ [GH#1232] broadcast-hid-discoveryd discovers HID devices on a LAN by

sending a discoveryd network broadcast probe. [Brendan Coles]

+ [GH#1236] broadcast-jenkins-discover discovers Jenkins servers on a LAN

by sending a discovery broadcast probe. [Brendan Coles]

+ [GH#1016][GH#1082] http-hp-ilo-info extracts information from HP

Integrated Lights-Out (iLO) servers. [rajeevrmenon97]

+ [GH#1243] http-sap-netweaver-leak detects SAP Netweaver Portal with the

Knowledge Management Unit enabled with anonymous access. [ArphanetX]

+ https-redirect detects HTTP servers that redirect to the same port, but

with HTTPS. Some nginx servers do this, which made ssl-* scripts not run

properly. [Daniel Miller]

+ [GH#1504] lu-enum enumerates Logical Units (LU) of TN3270E servers.

[Soldier of Fortran]

+ [GH#1633] rdp-ntlm-info extracts Windows domain information from RDP

services. [Tom Sellers]

+ smb-vuln-webexec checks whether the WebExService is installed and allows

code execution. [Ron Bowes]

+ smb-webexec-exploit exploits the WebExService to run arbitrary commands

with SYSTEM privileges. [Ron Bowes]

+ [GH#1457] ubiquiti-discovery extracts information from the Ubiquiti

Discovery service and assists version detection. [Tom Sellers]

+ [GH#1126] vulners queries the Vulners CVE database API using CPE

information from Nmap's service and application version detection.

[GMedian, Daniel Miller]

o [GH#1371] The macOS installer is now built for x86_64 architecture, not i386.

o [GH#1396] Fixed the Windows installer, which would replace the entire PATH

system variable with the path for Nmap if it exceeded 1024 bytes. This was

fixed by using the "large strings" build of NSIS to build the new installer.

[Daniel Miller]

o Replaced the addrset matching code that is used by --exclude and

--excludefile with a much faster implementation using a radix tree (trie).

https://seclists.org/nmap-dev/2018/q4/13

o [GH#1291][GH#34][GH#1339] Use pcap_create instead of pcap_live_open in

Nmap, and set immediate mode on the pcap descriptor. This solves packet

loss problems on Linux and may improve performance on other platforms.

[Daniel Cater, Mike Pontillo, Daniel Miller]

o [NSE][GH#1330] Fixed an infinite loop in tls-alpn when the server forces a

particular protocol. [Daniel Miller]

o [NSE] Collected utility functions for string processing into a new

library, stringaux.lua. [Daniel Miller]

o [NSE] New rand.lua library uses the best sources of random available on

the system to generate random strings. [Daniel Miller]

o [NSE] New library, oops.lua, makes reporting errors easy, with plenty of

debugging detail when needed, and no clutter when not. [Daniel Miller]

o [NSE] Collected utility functions for manipulating and searching tables

into a new library, tableaux.lua. [Daniel Miller]

o [NSE] New knx.lua library holds common functions and definitions for

communicating with KNX/Konnex devices. [Daniel Miller]

o [NSE][GH#1571] The HTTP library now provides transparent support for gzip-

encoded response body. (See https://github.com/nmap/nmap/pull/1571 for an

overview.) [nnposter]

o [Nsock][Ncat][GH#1075] Add AF_VSOCK (Linux VM sockets) functionality to

Nsock and Ncat. VM sockets are used for communication between virtual

machines and the hypervisor. [Stefan Hajnoczi]

o [Security][Windows] Address CVE-2019-1552 in OpenSSL by building with the

prefix "C:\Program Files (x86)\Nmap\OpenSSL". This should prevent

unauthorized users from modifying OpenSSL defaults by writing

configuration to this directory.

o [Security][GH#1147][GH#1108] Reduced LibPCRE resource limits so that

version detection can't use as much of the stack. Previously Nmap could

crash when run on low-memory systems against target services which are

intentionally or accidentally difficult to match. Someone assigned

CVE-2018-15173 for this issue. [Daniel Miller]

o [GH#1361] Deprecate and disable the -PR (ARP ping) host discovery

option. ARP ping is already used whenever possible, and the -PR option

would not force it to be used in any other case. [Daniel Miller]

o [NSE] bin.lua is officially deprecated. Lua 5.3, added 2 years ago in Nmap

7.25BETA2, has native support for binary data packing via string.pack and

string.unpack. All existing scripts and libraries have been updated.

[Daniel Miller]

o [NSE] Completely removed the bit.lua NSE library. All of its functions are

replaced by native Lua bitwise operations, except for `arshift`

(arithmetic shift) which has been moved to the bits.lua library. [Daniel

Miller]

o [NSE][GH#1571] The HTTP library is now enforcing a size limit on the

received response body. The default limit can be adjusted with a script

argument, which applies to all scripts, and can be overridden case-by-case

with an HTTP request option. (See https://github.com/nmap/nmap/pull/1571

for details.) [nnposter]

o [NSE][GH#1648] CR characters are no longer treated as illegal in script

XML output. [nnposter]

o [GH#1659] Allow resuming nmap scan with lengthy command line [Clément

Notin]

o [NSE][GH#1614] Add TLS support to rdp-enum-encryption. Enables determining

protocol version against servers that require TLS and lays ground work for

some NLA/CredSSP information collection. [Tom Sellers]

o [NSE][GH#1611] Address two protocol parsing issues in rdp-enum-encryption

and the RDP nse library which broke scanning of Windows XP. Clarify

protocol types [Tom Sellers]

o [NSE][GH#1608] Script http-fileupload-exploiter failed to locate its

resource file unless executed from a specific working

directory. [nnposter]

o [NSE][GH#1467] Avoid clobbering the "severity" and "ignore_404" values of

fingerprints in http-enum. None of the standard fingerprints uses these

fields. [Kostas Milonas]

o [NSE][GH#1077] Fix a crash caused by a double-free of libssh2 session data

when running SSH NSE scripts against non-SSH services. [Seth Randall]

o [NSE][GH#1565] Updates the execution rule of the mongodb scripts to be

able to run on alternate ports. [Paulino Calderon]

o [Ncat][GH#1560] Allow Ncat to connect to servers on port 0, provided that

the socket implementation allows this. [Daniel Miller]

o Update the included libpcap to 1.9.0. [Daniel Miller]

o [NSE][GH#1544] Fix a logic error that resulted in scripts not honoring the

smbdomain script-arg when the target provided a domain in the NTLM

challenge. [Daniel Miller]

o [Nsock][GH#1543] Avoid a crash (Protocol not supported) caused by trying

to reconnect with SSLv2 when an error occurs during DTLS connect. [Daniel

Miller]

o [NSE][GH#1534] Removed OSVDB references from scripts and replaced them

with BID references where possible. [nnposter]

o [NSE][GH#1504] Updates TN3270.lua and adds argument to disable TN3270E

[Soldier of Fortran]

o [GH#1504] RMI parser could crash when encountering invalid input [Clément

Notin]

o [GH#863] Avoid reporting negative latencies due to matching an ARP or ND

response to a probe sent after it was recieved. [Daniel Miller]

o [Ncat][GH#1441] To avoid confusion and to support non-default proxy ports,

option --proxy now requires a literal IPv6 address to be specified using

square-bracket notation, such as --proxy [2001:db8::123]:456. [nnposter]

o [Ncat][GH#1214][GH#1230][GH#1439] New ncat option provides control over

whether proxy destinations are resolved by the remote proxy server or

locally, by Ncat itself. See option --proxy-dns. [nnposter]

o [NSE][GH#1478] Updated script ftp-syst to prevent potential endless

looping. [nnposter]

o [GH#1454] New service probes and match lines for v1 and v2 of the Ubiquiti

Discovery protocol. Devices often leave the related service open and it

exposes significant amounts of information as well as the risk of being

used as part of a DDoS. New nmap-payload entry for v1 of the

protocol. [Tom Sellers]

o [NSE] Removed hostmap-ip2hosts.nse as the API has been broken for a while

and the service was completely shutdown on Feb 17th, 2019. [Paulino

Calderon]

o [NSE][GH#1318] Adds TN3270E support and additional improvements to

tn3270.lua and updates tn3270-screen.nse to display the new

setting. [mainframed]

o [NSE][GH#1346] Updates product codes and adds a check for response length

in enip-info.nse. The script now uses string.unpack. [NothinRandom]

o [Ncat][GH#1310][GH#1409] Temporary RSA keys are now 2048-bit to resolve a

compatibility issue with OpenSSL library configured with security level 2,

as seen on current Debian or Kali. [Adrian Vollmer, nnposter]

o [NSE][GH#1227] Fix a crash (double-free) when using SSH scripts against

non-SSH services. [Daniel Miller]

o [Zenmap] Fix a crash when Nmap executable cannot be found and the system

PATH contains non-UTF-8 bytes, such as on Windows. [Daniel Miller]

o [Zenmap] Fix a crash in results search when using the dir: operator:

AttributeError: 'SearchDB' object has no attribute 'match_dir'

[Daniel Miller]

o [Ncat][GH#1372] Fixed an issue with Ncat -e on Windows that caused early
