Nmap 5.10BETA2 released : Citrix scanning & xmas greetings

Nmap ("Network Mapper") is a free open sourceutility for network exploration or security auditing. It was designedto rapidly scan large networks, although it works fine against singlehosts. Nmap uses raw IP packets in novel ways to determine what hostsare available on the network, what services (application name andversion) those hosts are offering, what operating systems (and OSversions) they are running, what type of packet filters/firewalls arein use, and dozens of other characteristics. Nmap runs on most types ofcomputers and both console and graphical versions are available. Nmapis 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... ...

 [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]
