Sqlninja 0.2.6 "bunga bunga edition" is available! I have been extremely lazy in the last few months or so, and the new job is not really helping me in finding time and motivation to work much on this little old pet project of mine. However, the new version is finally ready! It is basically an official release with all the new features that have been in the SVN for a while (most of them for almost 1 year, ouch). More specifically:
ICMP-based shell (thanks Nico!)
CVE-2010-0232 support to escalate the sqlservr.exe process to SYSTEM (greetz Tavis!)
Header-based injection support
Grab it from the Download page and please report any bug you find :)
As for the reasons behind the "bunga bunga edition", see the FAQ.
Introduction
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.
Have a look at the flash demo and then feel free to download. It is released under the GPLv3
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
ICMP-tunneled shell, when no TCP/UDP ports are available for a direct/reverse shell but the DB can ping your box
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
Support for CVE-2010-0232, to escalate the privileges of sqlservr.exe to SYSTEM
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
