SQLninja 0.2.5 released

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.

Here’s a list of what SQLninja 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
• 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.

New features:

• Upload mode is not limited to files of 64k bytes anymore
• Uploading files is also *massively* faster
• Proxy support
• Support for token kidnapping
• Lots of other minor improvements.

SQLninja has been successfully tested on Linux, FreeBSD and Mac OS X.
