[Nmap v6.40] Free Security Scanner For Network Exploration & Security Audits

Nmap (“Network Mapper”) is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for network inventory, managing service upgrade schedules, monitoring host or service uptime, and many other tasks. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping)

Changelog v6.40
o [Ncat] Added --lua-exec. This feature is basically the equivalent of 'ncat
--sh-exec "lua <scriptname>"' and allows you to run Lua scripts with Ncat,
redirecting all stdin and stdout operations to the socket connection. See
http://nmap.org/book/ncat-man-command-options.html [Jacek Wielemborek]

o Integrated all of your IPv4 OS fingerprint submissions since January
(1,300 of them). Added 91 fingerprints, bringing the new total to 4,118.
Additions include Linux 3.7, iOS 6.1, OpenBSD 5.3, AIX 7.1, and more.
Many existing fingerprints were improved. Highlights:
http://seclists.org/nmap-dev/2013/q2/519. [David Fifield]

o Integrated all of your service/version detection fingerprints submitted
since January (737 of them)! Our signature count jumped by 273 to 8,979.
We still detect 897 protocols, from extremely popular ones like http, ssh,
smtp and imap to the more obscure airdroid, gopher-proxy, and
enemyterritory. Highlights: http://seclists.org/nmap-dev/2013/q3/80. [David Fifield]

o Integrated your latest IPv6 OS submissions and corrections. We're still
low on IPv6 fingerprints, so please scan any IPv6 systems you own or
administer and submit them to http://nmap.org/submit/. Both new
fingerprints (if Nmap doesn't find a good match) and corrections (if Nmap
guesses wrong) are useful. [David Fifield]

o [Nsock] Added initial proxy support to Nsock. Nmap version detection
and NSE can now establish TCP connections through chains of one or
more CONNECT or SOCKS4 proxies. Use the Nmap --proxies option with a
chain of one or more proxies as the argument (example:
http://localhost:8080,socks4://someproxy.example.com). Note that
only version detection and NSE are supported so far (no port
scanning or host discovery), and there are other limitations
described in the man page. [Henri Doreau]

o [NSE] Added 14 NSE scripts from 6 authors, bringing the total up to 446.
They are all listed at http://nmap.org/nsedoc/, and the summaries are
below (authors are listed in brackets):

+ hostmap-ip2hosts finds hostnames that resolve to the target's IP address
by querying the online database at http://www.ip2hosts.com (uses Bing
search results) [Paulino Calderon]

+ http-adobe-coldfusion-apsa1301 attempts to exploit an authentication
bypass vulnerability in Adobe Coldfusion servers (APSA13-01:
http://www.adobe.com/support/security/advisories/apsa13-01.html) to
retrieve a valid administrator's session cookie. [Paulino Calderon]

+ http-coldfusion-subzero attempts to retrieve version, absolute path of
administration panel and the file 'password.properties' from vulnerable
installations of ColdFusion 9 and 10. [Paulino Calderon]

+ http-comments-displayer extracts and outputs HTML and JavaScript
comments from HTTP responses. [George Chatzisofroniou]

+ http-fileupload-exploiter exploits insecure file upload forms in web
applications using various techniques like changing the Content-type
header or creating valid image files containing the payload in the
comment. [George Chatzisofroniou]

+ http-phpmyadmin-dir-traversal exploits a directory traversal
vulnerability in phpMyAdmin 2.6.4-pl1 (and possibly other versions) to
retrieve remote files on the web server. [Alexey Meshcheryakov]

+ http-stored-xss posts specially crafted strings to every form it
encounters and then searches through the website for those strings to
determine whether the payloads were successful. [George Chatzisofroniou]

+ http-vuln-cve2013-0156 detects Ruby on Rails servers vulnerable to
object injection, remote command executions and denial of service
attacks. (CVE-2013-0156) [Paulino Calderon]

+ ike-version obtains information (such as vendor and device type where
available) from an IKE service by sending four packets to the host.
This scripts tests with both Main and Aggressive Mode and sends multiple
transforms per request. [Jesper Kueckelhahn]

+ murmur-version detects the Murmur service (server for the Mumble voice
communication client) versions 1.2.X. [Marin Maržić]

+ mysql-enum performs valid-user enumeration against MySQL server using a
bug discovered and published by Kingcope
(http://seclists.org/fulldisclosure/2012/Dec/9). [Aleksandar Nikolic]

+ teamspeak2-version detects the TeamSpeak 2 voice communication server
and attempts to determine version and configuration information. [Marin

+ ventrilo-info detects the Ventrilo voice communication server service
versions 2.1.2 and above and tries to determine version and
configuration information. [Marin Maržić]

o Updated the Nmap license agreement to close some loopholes and stop some
abusers. It's particularly targeted at companies which distribute
malware-laden Nmap installers as we caught Download.com doing last
year--http://insecure.org/news/download-com-fiasco.html. The updated
license is in the all the normal places, including

o [NSE] Oops, there was a vulnerability in one of our 437 NSE scripts. If
you ran the (fortunately non-default) http-domino-enum-passwords script
with the (fortunately also non-default) domino-enum-passwords.idpath
parameter against a malicious server, it could cause an arbitrarily named
file to to be written to the client system. Thanks to Trustwave researcher
Piotr Duszynski for discovering and reporting the problem. We've fixed
that script, and also updated several other scripts to use a new
stdnse.filename_escape function for extra safety. This breaks our record
of never having a vulnerability in the 16 years that Nmap has existed, but
that's still a fairly good run! [David, Fyodor]

o Unicast CIDR-style IPv6 range scanning is now supported, so you can
specify targets such as en.wikipedia.org/120. Obviously it will take ages
if you specify a huge space. For example, a /64 contains
18,446,744,073,709,551,616 addresses. [David Fifield]

o It's now possible to mix IPv4 range notation with CIDR netmasks in target
specifications. For example, 192.168-170.4-100,200.5/16 is effectively the
same as 192.168.168-170.0-255.0-255. [David Fifield]

o Timeout script-args are now standardized to use the timespec that Nmap's
command-line arguments take (5s, 5000ms, 1h, etc.). Some scripts that
previously took an integer number of milliseconds will now treat that as a
number of seconds if not explicitly denoted as ms. [Daniel Miller]

o Nmap may now partially rearrange its target list for more efficient
host groups. Previously, a single target with a different interface,
or with an IP address the same as a that of a target already in the
group, would cause the group to be broken off at whatever size it
was. Now, we buffer a small number of such targets, and keep looking
through the input for more targets to fill out the current group.
[David Fifield]

o [Ncat] The -i option (idle timeout) now works in listen mode as well as
connect mode. [Tomas Hozza]

o [Ncat] Ncat now support chained certificates with the --ssl-cert
option. [Greg Bailey]

o [Nping] Nping now checks for a matching ICMP ID on echo replies, to avoid
receiving crosstalk from other ping programs running at the same
time. [David Fifield]

o [NSE] The ipOps.isPrivate library now considers the deprecated site-local
prefix fec0::/10 to be private. [Marek Majkowski]

o Nmap's routing table is now sorted first by netmask, then by metric.
Previously it was the other way around, which could cause a very general
route with a low metric to be preferred over a specific route with a
higher metric.

o Routes are now sorted to prefer those with a lower metric. Retrieval of
metrics is supported only on Linux and Windows. [David Fifield]

o Fixed a byte-ordering problem on little-endian architectures when doing
idle scan with a zombie that uses broken ID increments. [David Fifield]

o Stop parsing TCP options after reaching EOL in libnetutil. Bug reported by
Gustavo Moreira. [Henri Doreau]

o [NSE] The dns-ip6-arpa-scan script now optionally accepts "/" syntax for a
network mask. Based on a patch by Indula Nayanamith.

o [Ncat] Reduced the default --max-conns limit from 100 to 60 on Windows, to
stay within platform limitations. Suggested by Andrey Olkhin.

o Fixed IPv6 routing table alignment on NetBSD.
o Fixed our NSEDoc system so the author field uses UTF-8 and we can spell
people's name properly, even if they use crazy non-ASCII characters like
Marin Maržić. [David Fifield]

o UDP protocol payloads were added for detecting the Murmer service (a
server for the Mumble voice communication client) and TeamSpeak 2 VoIP

o [NSE] Added http-phpmyadmin-dir-traversal by Alexey Meshcheryakov.
o Updated libdnet to not SIOCIFNETMASK before SIOCIFADDR on OpenBSD. This
was reported to break on -current as of May 2013. [Giovanni Bechis]

o Fixed address matching for SCTP (-PY) ping. [Marin Maržić]
o Removed some non-ANSI-C strftime format strings ("%F") and
locale-dependent formats ("%c") from NSE scripts and libraries.
C99-specified %F was noticed by Alex Weber. [Daniel Miller]

o [Zenmap] Improved internationalization support:
+ Added Polish translation by Jacek Wielemborek.
+ Updated the Italian translation. [Giacomo]

o [Zenmap] Fixed internationalization files. Running in a language other
than the default English would result in the error "ValueError: too many
values to unpack". [David Fifield]

o [NSE] Updated the included Liblua from version 5.2.1 to 5.2.2. [Patrick

o [Nsock] Added a minimal regression test suite for Nsock. [Henri Doreau]
o [NSE] Updated the redis-brute and redis-info scripts to work against the
latest versions of redis server. [Henri Doreau]

o [Ncat] Fixed errors in connecting to IPv6 proxies. [Joachim Henke]
o [NSE] Updated hostmap-bfk to work with the latest version of their website
(bfk.de). [Paulino Calderon]

o [NSE] Added XML structured output support to:
+ xmpp-info, irc-info, sslv2, address-info [Daniel Miller]
+ hostmap-bfk, hostmap-robtex, hostmap-ip2hosts. [Paulino Calderon]
+ http-git.nse. [Alex Weber]

o Added new service probes for:
+ Erlang distribution nodes [Michael Schierl]
+ Minecraft servers. [Eric Davisson]
+ Hazelcast data grid. [Pavel Kankovsky]

o [NSE] Rewrote telnet-brute for better compatibility with a variety of
telnet servers. [nnposter]

o Fixed a regression that changed the number of delimiters in machine
output. [Daniel Miller]

o Fixed a regression in broadcast-dropbox-listener which prevented it from
producing output. [Daniel Miller]

o Handle ICMP type 11 (Time Exceeded) responses to port scan probes. Ports
will be reported as "filtered", to be consistent with existing Connect
scan results, and will have a reason of time-exceeded. DiabloHorn
reported this issue via IRC. [Daniel Miller]

o Add new decoders (BROWSER, DHCP6 and LLMNR) to broadcast-listener and
changed output of some of the decoders slightly. [Patrik Karlsson]

o The list of name servers on Windows now ignores those from inactive
interfaces. [David Fifield]

o Namespace the pipes used to communicate with subprocesses by PID, to avoid
multiple instances of Ncat from interfering with each other. Patch by
Andrey Olkhin.

o [NSE] Changed ip-geolocation-geoplugin to use the web service's new output
format. Reported by Robin Wood.

o Limited the number of open sockets in ultra_scan to FD_SETSIZE. Very fast
connect scans could write past the end of an fd_set and cause a variety of
nmap: scan_engine.cc:978: bool ConnectScanInfo::clearSD(int):
Assertion `numSDs > 0' failed.
select failed in do_one_select_round(): Bad file descriptor (9)
[David Fifield]

o Fixed a bug that prevented Nmap from finding any interfaces when one of
them had the type ARP_HDR_APPLETALK; this was the case for AppleTalk
interfaces. However, This support is not complete since AppleTalk
interfaces use different size hardware addresses than Ethernet. Nmap IP
level scans should work without any problem, please refer to the
'--send-ip' switch and to the following thread:
http://seclists.org/nmap-dev/2013/q1/214. This bug was reported by Steven
Gregory Johnson. [Daniel Miller]

o [Nping] Nping on Windows now skips localhost targets for privileged pings
on (with an error message) because those generally don't work. [David

o [Ncat] Ncat now keeps running in connect mode after receiving EOF from the
remote socket, unless --recv-only is in effect. [Tomas Hozza]

o Packet trace of ICMP packets now include the ICMP ID and sequence number
by default. [David Fifield]

o [NSE] Fixed various NSEDoc bugs found by David Matousek.
o [Zenmap] Zenmap now understands the NMAP_PRIVILEGED and NMAP_UNPRIVILEGED
environment variables. [Tyler Wagner]

o Added an ncat_assert macro. This is similar to assert(), but remains even
if NDEBUG is defined. Replaced all Ncat asserts with this. We also moved
operation with side effects outside of asserts as yet another layer of
bug-prevention [David Fifield].

o Added nmap-fo.xsl, contributed by Tilik Ammon. This converts Nmap XML into
XSL-FO, which can be converted into PDF using tools suck as Apache FOP.

o Increased the number of slack file descriptors not used during connect
scan. Previously, the calculation did not consider the descriptors used by
various open log files. Connect scans using a lot of sockets could fail
with the message "Socket creation in sendConnectScanProbe: Too many open
files". [David Fifield]

o Changed the --webxml XSL stylesheet to point to the new location of
nmap.xsl in the new repository (https://svn.nmap.org/nmap/docs/nmap.xsl).
It still may not work in web browsers due to same origin policy (see
http://seclists.org/nmap-dev/2013/q1/58). [David Fifield, Simon John]

o [NSE] The vulnerability library can now preserve vulnerability information
across multiple ports of the same host. The bug was reported by
iphelix. [Djalal Harouni]

o Removed the undocumented -q option, which renamed the nmap process to
something like "pine".

o Moved the Japanese man page from man1/jp to man1/ja. JP is a country code
while JA is a language code. Reported by Christian Neukirchen.

o [Nsock] Reworked the logging infrastructure to make it more flexible and
consistent. Updated Nmap, Nping and Ncat accordingly. Nsock log level can
now be adjusted at runtime by pressing d/D in nmap. [Henri Doreau, David

o [NSE] Fixed scripts using unconnected UDP sockets. The bug was reported by
Dhiru Kholia at http://seclists.org/nmap-dev/2012/q4/422. [David Fifield]

o Made some changes to Ndiff to reduce parsing time when dealing with large
Nmap XML output files. [Henri Doreau]

o Clean up the source code a bit to resolve some false positive issues
identified by the Parfait static code analysis program. Oracle apparently
runs this on programs (including Nmap) that they ship with Solaris. See
http://seclists.org/nmap-dev/2012/q4/504. [David Fifield]

o [Zenmap] Fixed a crash that could be caused by opening the About dialog,
using the window manager to close it, and opening it again. This was
reported by Yashartha Chaturvedi and Jordan Schroeder. [David Fifield]

o [Ncat] Made test-addrset.sh exit with nonzero status if any tests
fail. This in turn causes "make check" to fail if any tests fail.
[Andreas Stieger]

o Fixed compilation with --without-liblua. The bug was reported by Rick
Farina, Nikos Chantziaras, and Alex Turbov. [David Fifield]

o Fixed CRC32c calculation (as used in SCTP scans) on 64-bit
platforms. [Pontus Andersson]

o [NSE] Added multicast group name output to
broadcast-igmp-discovery.nse. [Vasily Kulikov]

o [NSE] Added new fingerprints for http-enum: Sitecore, Moodle, typo3,
SquirrelMail, RoundCube. [Jesper Kückelhahn]
