Sqlninja 0.2.3 is here!

Fancy going from a SQL Injection to a full GUI access on the DB server? What about extracting password hashes on the fly? 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 the latest release of sqlninja!
Have a look at the brand new flash demo and then feel free to download the tool. Angelo Dell'Aera and the Metasploit Development Team deserve special credit for this release. Happy hacking!!

Introduction

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.
It is released under the GPLv2 and it has been featured on SecurityHack's Top 15 Free SQL Injection Scanners, which is a good result for something that started as a small script written on-the-fly during a pen-test :)

Features

The full documentation can be found in the tarball and also here, but here's a list of what the Ninja 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

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

Sqlninja does not run on Windows and I am not planning a port in the near future
