CVE-2025-65883

Root command execution via stale session token

Published Dec 4, 2025 · Updated Dec 8, 2025

Insufficient session expiration in Genexis Platinum P4410 firmware P4410-V2-1.41 allows remote attackers on its LAN to execute commands as root. The logout handler leaves the administrator session token valid, and the diagnostic endpoint accepts that stale token with crafted requests. Exploitation requires an administrator to have logged out without rebooting the router; the resulting commands run with root privileges.
