Open ISES Tickets before 3.44.2 contains a reflected cross-site scripting vulnerability in add.php that allows authenticated attackers to inject arbitrary JavaScript by passing an unsanitized value through the ticket_id POST parameter directly into an HTML form input value attribute. Attackers can craft a malicious request containing a JavaScript payload that executes in the victim's browser when the response is rendered.
