Name of the Vulnerable Software and Affected Versions Open ISES Tickets versions prior to 3.44.2

Description A reflected cross-site scripting issue exists in the 'delete module.php' endpoint. Authenticated attackers can inject arbitrary JavaScript by providing unsanitized values through the module choice, flag, and confirmation POST parameters, which are then rendered directly into HTML content and form action attributes. This allows the execution of malicious scripts in the victim's browser when the response is rendered.

Recommendations Update to version 3.44.2 or later. As a temporary mitigation, restrict access to the 'delete module.php' endpoint or avoid using the module choice, flag, and confirmation parameters until the update is applied.
