Nmap 5.10BETA2 released : Citrix scanning & xmas greetings

Nmap ("Network Mapper") is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. 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. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free and open source (license).

  • Added 7 new NSE scripts for a grand total of 79! You can learn about
    them all at http://nmap.org/nsedoc/. Here are the new ones:
  • nfs-showmount displays NFS exports like "showmount -e" does. See
    http://nmap.org/nsedoc/scripts/nfs-showmount.html. [Patrik
    Karlsson]
  • ntp-info prints the time and configuration variables provided by
    an NTP service. It may get such interesting information as the
    operating system, server build date, and upstream time server IP
    address. See
    http://nmap.org/nsedoc/scripts/ntp-info.html. [Richard Sammet]
  • citrix-brute-xml uses the unpwdb library to guess credentials for
    the Citrix PN Web Agent Service. See
    http://nmap.org/nsedoc/scripts/citrix-brute-xml.html. [Patrik Karlsson]
  • citrix-enum-apps and citrix-enum-apps-xml print a list of published
    applications from the Citrix ICA Browser or XML service,
    respectively. See
    http://nmap.org/nsedoc/scripts/citrix-enum-apps.html and
    http://nmap.org/nsedoc/scripts/citrix-enum-apps-xml.html. [Patrik Karlsson]
  • citrix-enum-servers and citrix-enum-servers-xml.nse print a list
    of Citrix servers from the Citrix ICA Browser or XML service,
    respectively. See
    http://nmap.org/nsedoc/scripts/citrix-enum-servers.html and
    http://nmap.org/nsedoc/scripts/citrix-enum-servers-xml.html. [Patrik
    Karlsson]
  • We performed a memory consumption audit and made changes to
    dramatically reduce Nmap’s footprint. This improves performance on
    all systems, but is particularly important when running Nmap on
    small embedded devices such as phones. Our intensive UDP scan
    benchmark saw peak memory usage decrease from 34MB to 6MB, while OS
    detection consumption was reduced from 67MB to 3MB. Read about the
    changes at http://seclists.org/nmap-dev/2009/q4/663. Here are the
    highlights:
  • The size of the internal representation of nmap-os-db was reduced
    more than 90%. Peak memory consumption in our OS detection
    benchmark was reduced from 67MB to 3MB. [David]
  • The size of individual Port structures without service scan
    results was reduced about 70%. [Pavel Kankovsky]
  • When a port receives no response, Nmap now avoids allocating a
    Port structure at all, so scans against filtered hosts can be
    light on memory. [David]
  • David started a major service detection submission integration
    run. So far he has processed submissions since February for the
    following services: imap, pop3, afp, sip, printer, transmission,
    svnserve, vmware, domain, backdoor, finger, freeciv, hp, imaps, irc,
    landesk, netbios-ssn, netsupport, nntp, oracle, radmin, routersetup,
    rtorrent, serv-u, shoutcast, ssh, tcpmux, torrent, utorrent, vnc and
    ipp. The rest will come in the next release, along with full stats
    on the additions.
  • Added service detection probe for Kerberos (udp/88) and IBM DB2
    DAS (523/UDP). [Patrik Karlsson]
  • Added a UDP payload and service detection probe for Citrix
    MetaFrame, which typically runs on 1604/udp. [Thomas Buchanan]
  • Added a UDP SIPOptions service detection probe corresponding to the
    TCP one. [Patrik Karlsson, Matt Selsky, David Fifield]
  • Updated service detection signatures for Microsoft SQL Server 2005
    to detect recent Microsoft security update (MS09-062), and also
    updated ms-sql-info.nse to support MS SQL Server 2008
    detection. [Tom]
  • Nmap now provides Christmas greetings and a reminder of Xmas scan
    (-sX) when run in verbose mode on December 25. [Fyodor]
  • Removed a limitation of snmp.lua which only allowed it to properly
    encode OID component values up to 127. The bug was reported by
    Victor Rudnev. [David]
  • Nmap script output now uses two spaces of indention rather than
    three for the first level. This better aligns with the standard set by
    the stdnse.format_output function added in the last release. Output
    now looks like:
    8082/tcp open http Apache httpd 2.2.13 ((Fedora))
    |_http-favicon: Apache Web Server (seen on SuSE, Linux Tux favicon)
    |_html-title: Nmap - Free Security Scanner For Network Exploration & Securit...
    ...
    Host script results:
    | smb-os-discovery:
    | OS: Unix (Samba 3.4.2-0.42.fc11)
    | Name: Unknown\Unknown
    |_ System time: 2009-11-24 17:19:21 UTC-8
    |_smbv2-enabled: Server doesn’t support SMBv2 protocol
    [Fyodor]
  • [NSE] Fixed (we hope) a deadlock we were seeing when doing a
    favicon.nse survey against millions of hosts. We now restore all
    threads that are waiting on a socket lock when a thread relinquishes
    its lock. We expect only one of them to be able to grab the newly
    freed lock, and the rest to go back to waiting. [David, Patrick]
  • [Zenmap] Fixed a crash when filtering with inroute: in scans without
    traceroute data. (KeyError: ’hops’) [David]
  • [NSE] Use a looser match pattern in auth-owners.nse for retrieving
    the owner out of an identd response. See
    http://seclists.org/nmap-dev/2009/q4/549. [Richard Sammet]
  • Improved some Cyrus pop3 and Polycom SoundStation sip match
    lines. [Matt Selsky]
  • [Ncat] In the Windows version of netrun, we weren’t noticing when a
    command fails to be executed (when CreateProcess fails). We now see
    the return value and close the socket to disconnect the
    client. [David]
  • [NSE] Updated http-iis-webdav-vuln to run against SSL-enabled
    servers [Ron]
  • [NSE] Improved db2-info to set port product and state (rather than
    just port.version.name and confidence) when a DB2 service is
    positively identified. Error reporting was improved as well. [Tom]
