Nmap v6.46 Released

Nmap v6.46 Released

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 6.46 [2014-04-18]

  • [NSE] Made numerous improvements to ssl-heartbleed to provide more reliable detection of the vulnerability.
  • [Zenmap] Fixed a bug which caused this crash message: “IOError: [Errno socket error] [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond”. The bug was caused by us adding a DOCTYPE definition to Nmap’s XML output which caused Python’s XML parser to try and fetch the DTD every time it parses an XML file. We now override that DTD-fetching behavior. [Daniel Miller]
  • [NSE] Fix some bugs which could cause snmp-ios-config and snmp-sysdescr scripts to crash (http://seclists.org/nmap-dev/2014/q2/120) [Patrik Karlsson]
  • [NSE] Improved performance of citrixlua library when handling large XML responses containing application lists. [Tom Sellers]

Changelog v6.45 [2014-04-11]


  • [NSE] Add ssl-heartbleed script to detect the Heartbleed bug in OpenSSL CVE-2014-0160 [Patrik Karlsson]
  • [NSE] Fixed an error-handling bug in socks-open-proxy that caused it to fail when scanning a SOCKS4-only proxy. Reported on IRC by Husky. [Daniel Miller]
  • [NSE] Improved ntp-info script to handle underscores in returned data. [nnposter]
  • [NSE] Add quake1-info script for retrieving server and player information from Quake 1 game servers. Reports potential DoS amplification factor. [Ulrik Haugen]
  • [NSE] Add unicode library for decoding and encoding UTF-8, UTF-16, CP437 and other character sets to Unicode code points. Scripts that previously just added or skipped nulls in UTF-16 data can use this to support non-ASCII characters. [Daniel Miller]
  • When doing a ping scan (-sn), the –open option will prevent down hosts from being shown when -v is specified. This aligns with similar output for other scan types. [Daniel Miller]
  • [Ncat] Added support for socks5 and corresponding regression tests. [Marek Lucaszuk, Petr Stodulka]
  • [NSE] Add http-ntlm-info script for getting server information from Web servers that require NTLM authentication. [Justin Cacak]
  • Added TCP support to dns.lua. [John Bond]
  • Added safe fd_set operations. This makes nmap fail gracefully instead of crashing when the number of file descriptors grows over FD_SETSIZE. Jacek Wielemborek reported the crash. [Henri Doreau]
  • [NSE] Added tls library for functions related to SSLv3 and TLS messages. Existing ssl-enum-ciphers, ssl-date, and tls-nextprotoneg scripts were updated to use this library. [Daniel Miller]
  • [NSE] Add sstp-discover script to discover Microsoft’s Secure Socket Tunnelling Protocol (http://msdn.microsoft.com/en-us/library/cc247338.aspx) [Niklaus Schiess]
  • [NSE] Added unittest library and NSE script for adding unit tests to NSE libraries. See unittest.lua for examples, and run `nmap –script=unittest –script-args=unittest.run -d` to run the tests. [Daniel Miller]
  • Updated bundled liblua from 5.2.2 to 5.2.3 (bugfix release) [Daniel Miller]
  • Added version detection signatures and probes for a bunch of Android remote mouse/keyboard servers, including AndroMouse, AirHID, Wifi-mouse, and RemoteMouse. [Paul Hemberger]
  • [NSE] Added allseeingeye-info for gathering information from games using this query protocol. A version detection probe was also added. [Marin Maržić]
  • [NSE] Add freelancer-info to gather information about the Freelancer game server. Also added a related version detection probe and UDP protocol payload for detecting the service. [Marin Maržić]
  • [Ncat] Fixed compilation when –without-liblua is specified in configure (an #include needed an ifdef guard). [Quentin Glidic]
  • [NSE] Add http-server-header script to grab the Server header as a last-ditch effort to get a software version. This can’t be done as a softmatch because of the need to match non-HTTP services that obey some HTTP requests. [Daniel Miller]
  • [NSE] Add rfc868-time script to get the date and time from an RFC 868 Time server. [Daniel Miller]
  • [NSE] Add weblogic-t3-info script that detects the T3 RMI protocol used by Oracle/BEA Weblogic. Extracts the Weblogic version, as well [Alessandro Zanni, Daniel Miller]
  • Fixed a bug in libdnet with handling interfaces with AF_LINK addresses on FreeBSD >9 reported by idwer on IRC. Likely affected other *BSDs. Handled by skipping these non-network addresses. [Daniel Miller]
  • Fixed a bug with UDP checksum calculation. When the UDP checksum is zero (0x0000), it must be transmitted as 1’s-complement -0 (0xffff) to avoid ambiguity with +0, which indicates no checksum was calculated. This affected UDP on IPv4 only. Reported by Michael Weber. [Daniel Miller]
  • [NSE] Removed a fixed value (28428) which was being set for the Request ID in the snmpWalk library function; a value based on nmap.clock_ms will now be set instead. [jah]
  • [NSE] Add http-iis-short-name-brute script that detects Microsoft IIS servers vulnerable to a file/folder name disclosure and a denial of service vulnerability. The script obtains the “shortnames” of the files and folders in the webroot folder. [Paulino Calderon]
  • Idle scan now supports IPv6. IPv6 packets don’t usually come with fragments identifiers like IPv4 packets do, so new techniques had to be developed to make idle scan possible. The implementation is by Mathias Morbitzer, who made it the subject of his master’s thesis.
  • [NSE] Add http-dlink-backdoor script that detects DLink routers with firmware backdoor allowing admin access over HTTP interface. [Patrik Karlsson]
  • The ICMP ID of ICMP probes is now matched against the sent ICMP ID, to reduce the chance of false matches. Patch by Chris Johnson.
  • [NSE] Made telnet-brute support multiple parallel guessing threads, reuse connections, and support password-only logins. [nnposter]
  • [NSE] Made the table returned by ssh1.fetch_host_key contain a “key” element, like that of ssh2.fetch_host_key. This fixed a crash in the ssh-hostkey script reported by Dan Farmer and Florian Pelgrim. The “key” element of ssh2.fetch_host_key now is base64-encoded, to match the format used by the known_hosts file. [David Fifield]
  • [Nsock] Handle timers and timeouts via a priority queue (using a heap) for improved performance. Nsock now only iterates over events which are completed or expired instead of inspecting the entire event set at each iteration. [Henri Doreau]
  • [NSE] Update dns-cache-snoop script to use a new list of top 50 domains rather than a 2010 list. [Nicolle Neulist]
  • [NSE] Added the qconn-exec script by Brendan Coles, which tests the QNX QCONN service for remote command execution.
  • [Zenmap] Fixed a crash that would happen when you entered a search term starting with a colon: “AttributeError: ‘FilteredNetworkInventory’ object has no attribute ‘match_'”. Reported by Kris Paernell. [David Fifield]
  • [Ncat] Added NCAT_PROTO, NCAT_REMOTE_ADDR, NCAT_REMOTE_PORT, NCAT_LOCAL_ADDR and NCAT_LOCAL_PORT environment variables being set in all –*-exec child processes.
