CVE-2025-22450Network attack vector

Unauthenticated firewall disablement via undocumented function

Published Jan 22, 2025 · Updated Feb 12, 2025

Undocumented functionality in UD-LT2 firmware 1.00.008_SE and earlier allows remote attackers to disable the LAN-side firewall. The vendor states that the hidden function opens specific ports but has not disclosed the triggering request, endpoint, or firmware logic. No authentication or user interaction is required; successful use exposes selected LAN services to connections normally blocked by the firewall.
