CVE-2023-48858Public exploitNetwork attack vector

Reflected XSS via unencoded login URL path

Published Jan 17, 2024 · Updated Jun 2, 2025

Reflected XSS in the login page of Armex ABO.CMS 5.9 allows remote attackers to execute script in a visitor's browser via a crafted URL. The login.php page places attacker-controlled URL path content into its HTML response without neutralizing tag and event-handler syntax. Exploitation requires a visitor to open the crafted URL; script then runs in the page's browser origin, enabling page-content modification and browser-accessible data disclosure.
