sqlninja 0.2.1-r1 – SQL Injection Tool for MS-SQL Released for Download

Outsmart Malicious Hackers

Sqlninja is a tool targeted to exploit SQL Injection vulnerabilities on a web application that uses Microsoft SQL Server as its back-end. Its main goal is to provide a remote shell 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.

It is written in perl and so far has been successfully tested on:

  • Linux
  • FreeBSD
  • Mac OS X


  • 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 (check the documentation for details about how this works)

What’s New

  • A new flavor of bruteforce attack, performed remotely on the target DB Server by using its own CPU resources (use it with caution !)
  • Detection of the authentication mode (mixed or Windows-only), which is useful to understand whether the bruteforce attack to the ‘sa’ account can succeed or not
  • Documentation is now in HTML format, which should make things much easier for new users
  • Several bugfixes and minor improvements

    we’ve been playing with this tool alot at LSO, its really pretty handy. it was also enumerate the account name if it isnt sa, which is handy, you can then throw passwords at the right username.

    very functional with mssql2000 somewhat less with 2005 but thats the nature of the beast

    Yeah, I wish I had some more time on my hands as well. I always thought that sql-injections are the most fun to play with….

    It appears that we all suffer from the same lack of time to do all the fun things like test these applications.


    What exactly is your role? Are you a sec eng?
