SQL Ninja

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.

Main 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
  • 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

Supported OS:

  • Linux
  • FreeBSD
  • Mac OS X
