Technical details

A reflected cross-site scripting (XSS) vulnerability exists in Open ISES Tickets versions prior to 3.44.2 within the patient.php file. The application fails to sanitize the 'id' and 'ticket_id' GET parameters before embedding them into an HTML form's action URL. An authenticated attacker can exploit this by crafting a URL containing a malicious JavaScript payload and enticing a victim to visit it. When the victim's browser renders the page, the payload executes in the context of the victim's session. This can result in session hijacking or unauthorized data manipulation. The issue was addressed in version 3.44.2 by implementing proper input validation using intval() and output encoding.
