SQLninja - An SQL Server injection & takeover tool

Fancy going from a SQL Injection on Microsoft SQL Server to a full GUI access on the DB? Take a few new SQL Injection tricks, add a couple of remote shots in the registry to disable Data Execution Prevention, mix with a little Perl that automatically generates a debug script, put all this in a shaker with a Metasploit wrapper, shake well and you have just one of the attack modules of sqlninja!

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 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 (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

Platforms supported

Sqlninja is written in Perl and should run

on any UNIX based platform with a Perl interpreter, as long as all

needed modules have been installed. So far it has been successfully

tested on:

• Linux
• FreeBSD
• Mac OS X
