Nmap 6.47 - Free Security Scanner For Network Exploration & Security Audits

Read

Nmap is a utility for port scanning large networks, although it works fine for single hosts. Sometimes you need speed, other times you may need stealth. In some cases, bypassing firewalls may be required. Not to mention the fact that you may want to scan different protocols (UDP, TCP, ICMP, etc.). Nmap supports Vanilla TCP connect() scanning, TCP SYN (half open) scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy (bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses some packet filters), TCP ACK and Window scanning, UDP raw ICMP port unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Direct (non portmapper) RPC scanning, Remote OS Identification by TCP/IP Fingerprinting, and Reverse-ident scanning. Nmap also supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings.

Nmap is ...

Flexible: Supports dozens of advanced techniques for mapping out networks filled with IP filters, firewalls, routers, and other obstacles. This includes many port scanning mechanisms (both TCP & UDP), OS detection, version detection, ping sweeps, and more. See the documentation page.
Powerful: Nmap has been used to scan huge networks of literally hundreds of thousands of machines.
Portable: Most operating systems are supported, including Linux, Microsoft Windows, FreeBSD, OpenBSD, Solaris, IRIX, Mac OS X, HP-UX, NetBSD, Sun OS, Amiga, and more.
Easy: While Nmap offers a rich set of advanced features for power users, you can start out as simply as "nmap -v -A targethost". Both traditional command line and graphical (GUI) versions are available to suit your preference. Binaries are available for those who do not wish to compile Nmap from source.
Free: The primary goals of the Nmap Project is to help make the Internet a little more secure and to provide administrators/auditors/hackers with an advanced tool for exploring their networks. Nmap is available for free download, and also comes with full source code that you may modify and redistribute under the terms of the license.
Well Documented: Significant effort has been put into comprehensive and up-to-date man pages, whitepapers, tutorials, and even a whole book! Find them in multiple languages here.
Supported: While Nmap comes with no warranty, it is well supported by a vibrant community of developers and users. Most of this interaction occurs on the Nmap mailing lists. Most bug reports and questions should be sent to the nmap-dev list, but only after you read the guidelines. We recommend that all users subscribe to the low-traffic nmap-hackers announcement list. You can also find Nmap on Facebook and Twitter. For real-time chat, join the #nmap channel on Freenode or EFNet.
Acclaimed: Nmap has won numerous awards, including "Information Security Product of the Year" by Linux Journal, Info World and Codetalker Digest. It has been featured in hundreds of magazine articles, several movies, dozens of books, and one comic book series. Visit the press pagefor further details.
Popular: Thousands of people download Nmap every day, and it is included with many operating systems (Redhat Linux, Debian Linux, Gentoo, FreeBSD, OpenBSD, etc). It is among the top ten (out of 30,000) programs at the Freshmeat.Net repository. This is important because it lends Nmap its vibrant development and user support communities.

Changelog Nmap 6.47:

o Integrated all of your IPv4 OS fingerprint submissions since June 2013
  (2700+ of them). Added 366 fingerprints, bringing the new total to 4485.
  Additions include Linux 3.10 - 3.14, iOS 7, OpenBSD 5.4 - 5.5, FreeBSD 9.2,
  OS X 10.9, Android 4.3, and more. Many existing fingerprints were improved.
  Highlights: http://seclists.org/nmap-dev/2014/q3/325 [Daniel Miller]

o (Windows, RPMs) Upgraded the included OpenSSL to version 1.0.1i. [Daniel Miller]

o (Windows) Upgraded the included Python to version 2.7.8. [Daniel Miller]

o Removed the External Entity Declaration from the DOCTYPE in Nmap's XML. This
  was added in 6.45, and resulted in trouble for Nmap XML parsers without
  network access, as well as increased traffic to Nmap's servers. The doctype
  is now:
  

o [Ndiff] Fixed the installation process on Windows, which was missing the
  actual Ndiff Python module since we separated it from the driver script.
  [Daniel Miller]

o [Ndiff] Fixed the ndiff.bat wrapper in the zipfile Windows distribution,
  which was giving the error, "\Microsoft was unexpected at this time." See
  https://support.microsoft.com/kb/2524009 [Daniel Miller]

o [Zenmap] Fixed the Zenmap .dmg installer for OS X. Zenmap failed to launch,
  producing this error:
    Could not import the zenmapGUI.App module:
    'dlopen(/Applications/Zenmap.app/Contents/Resources/lib/python2.6/lib-dynload/glib/_glib.so, 2):
    Library not loaded: /Users/david/macports-10.5/lib/libffi.5.dylib\n
    Referenced from:
    /Applications/Zenmap.app/Contents/Resources/lib/python2.6/lib-dynload/glib/_glib.so\n
    Reason: image not found'.

o [Ncat] Fixed SOCKS5 username/password authentication. The password length was
  being written in the wrong place, so authentication could not succeed.
  Reported with patch by Pierluigi Vittori.

o Avoid formatting NULL as "%s" when running nmap --iflist. GNU libc converts
  this to the string "(null)", but it caused segfault on Solaris. [Daniel Miller]

o [Zenmap][Ndiff] Avoid crashing when users have the antiquated PyXML package
  installed. Python tries to be nice and loads it when we import xml, but it
  isn't compatible. Instead, we force Python to use the standard library xml
  module. [Daniel Miller]

o Handle ICMP admin-prohibited messages when doing service version detection.
  Crash reported by Nathan Stocks was: Unexpected error in NSE_TYPE_READ
  callback.  Error code: 101 (Network is unreachable) [David Fifield]

o [NSE] Fix a bug causing http.head to not honor redirects. [Patrik Karlsson]

o [Zenmap] Fix a bug in DiffViewer causing this crash:
     TypeError: GtkTextBuffer.set_text() argument 1 must be string or read-only
     buffer, not NmapParserSAX
  Crash happened when trying to compare two scans within Zenmap. [Daniel Miller]

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

By 0x000216

Read

0 Comments

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 "' 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
Maržić]

+ 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

https://svn.nmap.org/nmap/COPYING.

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
software.

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
Donnelly]

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
crashes:
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
Fifield]

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
Fifield]

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]
