A Reflected Cross-Site Scripting (XSS) vulnerability exists in LMS (LAN Management System) before commit 9c5651b in the "dbrecover.php" and "netremap.php" modules where unsanitized GET parameters are directly embedded into HTML output. This allows an attacker to inject arbitrary JavaScript when an authenticated user clicks a crafted link, provided the required conditions (such as a network defined in the system) are met.
