CVE-2025-63229Public exploitNetwork attack vector

Browser-session hijacking via reflected m parameter

Published Nov 18, 2025 · Updated Nov 19, 2025

Reflected XSS in Mozart FM Transmitter WEBMOZZI-00287 allows remote attackers to run script in a victim's browser via a crafted URL. The /main0.php endpoint returns the m query parameter in generated HTML without neutralizing script markup, causing the browser to execute the injected payload. Exploitation requires a victim to open the attacker-crafted request; script then runs in the management interface's browser context and can read session data or issue unauthorized actions.
