MAGESH-K21 Online-College-Event-Hall-Reservation-System booktime.php cross site scripting

Successful exploitation of CVE-2024-2523 allows an attacker to execute arbitrary JavaScript code within the context of a user's browser session on the Online-College-Event-Hall-Reservation-System. This can lead to session hijacking, credential theft, and defacement of the application. An attacker could potentially gain access to sensitive administrative functions if they target an administrator's session. The impact is amplified if the system is used to manage sensitive student or event data, as attackers could potentially modify or steal this information.

Administrators and users with access to the /admin/booktime.php page are at the highest risk. Organizations using the Online-College-Event-Hall-Reservation-System in environments with limited security controls or those that have not implemented proper input validation are particularly vulnerable. Shared hosting environments where multiple users share the same server resources are also at increased risk.

• php: Examine /admin/booktime.php for unsanitized user input handling the 'id' parameter. Search for instances where user input is directly outputted to the HTML without proper encoding.

// Example of vulnerable code
<?php
echo $_GET['id']; // Vulnerable to XSS
?>

• generic web: Monitor access logs for unusual requests to /admin/booktime.php with suspicious parameters in the 'id' field. Look for patterns indicative of XSS attempts. • generic web: Check response headers for signs of XSS payloads being reflected in the HTML content. Use browser developer tools to inspect the DOM for unexpected script tags.

The primary mitigation for CVE-2024-2523 is to upgrade to version 1.0.1 of the Online-College-Event-Hall-Reservation-System. If upgrading immediately is not feasible, consider implementing input validation and output encoding on the 'id' parameter in /admin/booktime.php to sanitize user-supplied data. Web application firewalls (WAFs) configured to detect and block XSS payloads can also provide a temporary layer of protection. After upgrading, verify the fix by attempting to inject a simple XSS payload (e.g., <script>alert(1)</script>) into the 'id' parameter and confirming that the script is not executed.
