Open ISES Tickets before 3.44.2 contains a reflected cross-site scripting vulnerability in ics205.php that allows authenticated attackers to inject arbitrary JavaScript by passing an unsanitized value through the frm_add_str POST parameter directly into an HTML form hidden 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.
