Technical details

A reflected cross-site scripting (XSS) vulnerability exists in Open ISES Tickets versions prior to 3.44.2. The flaw is located in 'routes_i.php' (and several other files including 'routes_nm.php') where the 'ticket_id' GET/POST parameter is rendered into HTML hidden input value attributes without proper sanitization or encoding. An authenticated attacker can exploit this by crafting a malicious URL or form submission containing a JavaScript payload. When a victim visits the link, the payload executes in the context of their session, potentially allowing for session hijacking or unauthorized data modification. The vendor has addressed this in version 3.44.2 by implementing 'intval()' and 'htmlspecialchars()' for input validation.
