This is Bernardo's work but not mine. I re-post here for educational purpose only. It is because I enjoy his videos very much and I am afraid of losing them.

Demonstration of sqlmap command execution features: sqlmap is launched against a PHP test page hosted on a Debian GNU/Linux 5.0 server with back-end database management system being PostgreSQL 8.4.

The tool is instructed to identify possible SQL injections and exploit them by executing a command on the database server operating system. sqlmap first uploads a dynamic-linked library (DLL) used to create two user-defined functions (sys_exec() and sys_eval()) in the database. Then it asks the user if he wants to retrieve the command standard output.

If the answer is positive, sqlmap executes the command once and stores its standard output in a support table. Either boolean-based blind SQL injection or UNION query SQL injection technique is used to dump the entry of this table and delete it afterwards. This technique is also implemented for MySQL.

On Microsoft SQL Server, xp_cmdshell extended stored procedure is used to execute commands on the underlying operating system.


python -u --os-cmd "id" -v 1

That's all! See you.
