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

[ad]

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
