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.
Key Features
- Fingerprint of the remote SQL Server (version, user performing the queries, user privileges, xp_cmdshell availability, DB authentication mode)
- Data extraction, time-based or via a DNS tunnel
- Integration with Metasploit3, to obtain a graphical access to the remote DB server through a VNC server injection or just to upload Meterpreter
- Upload of executables using only normal HTTP requests (no FTP/TFTP needed), via vbscript or debug.exe
- 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
- ICMP-tunneled shell, when no TCP/UDP ports are available for a direct/reverse shell but the DB can ping your box
- 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
- 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
- Evasion techniques to confuse a few IDS/IPS/WAF
- 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
