Description

sqlmap is a tool that automates the process of detecting and exploiting SQL injections and taking over of database servers.

Installation

Via the packages

# apt-get install sqlmap

From sources

# cd /usr/local/src/

$ ./sqlmap.py -u http://192.168.60.138 --forms --dbms=MySQL

Increasing risk and level parameters
