# Date: 07/10/2021
# Exploit Author: Hubert Wojciechowski
# Contact Author: snup.php@gmail.com
# Vendor Homepage: https://www.sourcecodester.com
# Software Link: https://www.sourcecodester.com/php/14909/online-traffic-offense-management-system-php-free-source-code.html
# Version: 1.0
# Testeted on: Windows 10 using XAMPP, Apache/2.4.48 (Win64) OpenSSL/1.1.1l PHP/7.4.23

### RCE - Remote Code Execution

# All requests can be sent by both an authenticated and a non-authenticated user

# RCE - we can exploit the RCE vulnerability in several ways:

* Drivers List can add any attachment as photo - http://localhost/traffic_offense/classes/Master.php?f=save_driver

* System information file add as system logo or portal cover - http://localhost/traffic_offense/admin/?page=system_info

* User profile edit avatar - http://localhost/traffic_offense/admin/?page=user

* Make new user and add evil avatar - http://localhost/traffic_offense/admin/?page=user/manage_user

* Edit other user and change his avatar to webshell - http://localhost/traffic_offense/admin/?page=user/manage_user&id=2
