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.
Features
- 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
Compatibility
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.
