What is sqlmap?
SQLMap is a tool to exploit the SQL injection vulnerability. This tool automates the attack in order to exploit the page.
To begin with I would like to leave the official page here:
http: // sqlmap.org /
Sqlmap is a tool that works in python in its versions: 2.6, 2.7 and 3.x on all platforms, so there is no problem to use it, personally I have used it in windows, linux and in termux and it works excellent in all of them.
