## Technical details

A reflected cross-site scripting (XSS) vulnerability exists in Open ISES Tickets before version 3.44.2 within the 'patient_w.php' component. The application fails to sanitize the 'id' and 'ticket_id' GET parameters before embedding them directly into an HTML form's action URL. An authenticated attacker can exploit this by tricking a victim into clicking a malicious URL containing a JavaScript payload. When the victim's browser renders the response, the payload executes within the context of the victim's session. This vulnerability was addressed in version 3.44.2 by implementing proper input validation using 'intval()' and 'htmlspecialchars()'.
