Description
QloApps through 1.7.0 contains a reflected cross-site scripting vulnerability in the back-office Hotel Reservation System Book Now search, where date_to and id_room_type parameters are copied into template variables without validation. Attackers can craft a malicious link containing JavaScript payload in these parameters that executes in an authenticated administrator's session when the victim follows the link.
