Sqlninja 0.2.6

Sqlninja 0.2.6 "bunga bunga edition" is available! I have been extremely lazy in the last few months or so, and the new job is not really helping me in finding time and motivation to work much on this little old pet project of mine. However, the new version is finally ready! It is basically an official release with all the new features that have been in the SVN for a while (most of them for almost 1 year, ouch). More specifically:
ICMP-based shell (thanks Nico!)
CVE-2010-0232 support to escalate the sqlservr.exe process to SYSTEM (greetz Tavis!)
Header-based injection support
Grab it from the Download page and please report any bug you find :)

Sqlninja’s goal is to exploit SQL injection vulnerabilities on web applications that use Microsoft SQL Server as back end. It is released under the GPLv3.There are a lot of other SQL injection tools out there but sqlninja, instead of extracting the data, focuses on getting an interactive shell on the remote DB server and using it as a foothold in the target network.

Here’s what it does:
  • Fingerprint of the remote SQL Server (version, user performing the queries, user privileges, xp_cmdshell availability, DB authentication mode)
  • Bruteforce of 'sa' password (in 2 flavors: dictionary-based and incremental)
  • Privilege escalation to sysadmin group if 'sa' password has been found
  • Creation of a custom xp_cmdshell if the original one has been removed
  • Upload of netcat (or any other executable) using only normal HTTP requests (no FTP/TFTP needed)
  • TCP/UDP portscan from the target SQL Server to the attacking machine, in order to find a port that is allowed by the firewall of the target network and use it for a reverse shell
  • Direct and reverse bindshell, both TCP and UDP
  • ICMP-tunneled shell, when no TCP/UDP ports are available for a direct/reverse shell but the DB can ping your box
  • DNS-tunneled pseudo-shell, when no TCP/UDP ports are available for a direct/reverse shell, but the DB server can resolve external hostnames (check the documentation for details about how this works)
  • Evasion techniques to confuse a few IDS/IPS/WAF
  • Integration with Metasploit3, to obtain a graphical access to the remote DB server through a VNC server injection
  • Integration with churrasco.exe, to escalate privileges to SYSTEM on w2k3 via token kidnapping
  • Support for CVE-2010-0232, to escalate the privileges of sqlservr.exe to SYSTEM
