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 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.
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 (check the documentation for details about how this works)
