CVE-2024-12400Public exploitNetwork attack vector

Reflected XSS via unescaped administrative page URLs

Published Jan 30, 2025 · Updated Jan 30, 2025

Reflected XSS in GoodLayers Tour Master before 5.3.5 allows remote attackers to run script in an administrator's browser via a crafted URL. Administrative pages place a generated page URL containing attacker-controlled query text into an HTML attribute without escaping it. Exploitation requires an authenticated administrator to open the link and, for the documented room-order page, at least one room order to exist.
