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 a remote shell 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 written in Perl, it is released under the GPLv2 and so far has been successfully tested on:
* Linux
* FreeBSD
* Mac OS X
Features
* Fingerprint of the remote SQL Server (version, user performing the queries, user privileges, xp_cmdshell availability, authentication mode)
* Bruteforce of ’sa’ password, both dictionary-based and incremental
* Privilege escalation to ’sa’ if its password has been found
* Creation of a custom xp_cmdshell if the original one has been disabled
* Upload of netcat.exe (or any other executable) using only 100% ASCII GET/POST requests, so no need for FTP connections
* 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
* What’s new
* Evasion techniques, in order to obfuscate the injected code and confuse/bypass signature-based IPS and application firewalls
* A more sophisticated upload module
* A new ‘blind execution’ attack mode, useful to issue commands and performs diagnostics when other modes fail
* Automatic URL-encoding now is performed only on sqlninja generated SQL code, giving the user a more granular control on the exploit strings
