sqlninja v0.2.5 Released – Microsoft SQL Server (MS-SQL) SQL Injection Vulnerability Tool

Your website & network are Hackable

It’s been 2 years, but a new version of sqlninja is out at Sourceforge, we wrote about the previous release back in 2008 and we’ve actually been following this tool since 2006!

Sqlninja is a tool to exploit SQL Injection vulnerabilities on a web application that uses Microsoft SQL Server as its back-end. Its main goal is to provide an interactive access on the vulnerable DB server, even in a very hostile environment. It should be used by penetration testers to help and automate the process of taking over a DB Server when a SQL Injection vulnerability has been discovered.


  • 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
  • DNS-tunneled pseudo-shell, when no TCP/UDP ports are available for a direct/reverse shell, but the DB server can resolve external hostnames
  • 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

What’s New?

  • Proxy support (it was about time!)
  • No more 64k bytes limit in upload mode
  • Upload mode is also massively faster
  • Privilege escalation through token kidnapping (kudos to Cesar Cerrudo)
  • Other minor improvements


It is written in Perl, it is released under the GPLv2 and so far has been successfully tested on:

  • Linux
  • FreeBSD
  • Mac OS X

    It’s about bloody time! I’ve been waiting for proxy support for sqlninja for quite a while now. It’ll be nice to finally be able to hook sqlninja directly into burpsuite.
