# 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

### 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

## Example 1 - Reading any PHP file from the server

Example vuln scripts:
http://localhost/traffic_offense/index.php?p=
http://localhost/traffic_offense/admin/?page=

# Request reading rrr.php file from other user in serwer
