## Technical details

A reflected cross-site scripting (XSS) vulnerability exists in Armiya Information Technologies Ltd. Co. Access Control System (GKS) versions prior to Version 2. The flaw stems from the improper neutralization of user-supplied input during web page generation (CWE-79). An attacker with low-level privileges can exploit this by tricking a victim into interacting with a specially crafted link, allowing the execution of arbitrary JavaScript in the context of the victim's browser session.
