CVE-2024-52564Known exploitationNetwork attack vector

Unauthenticated command execution via hidden firewall control

Published Dec 5, 2024 · Updated Jan 29, 2025

Undocumented functionality in UD-LT1 and UD-LT1/EX firmware 2.1.8 and earlier allows remote attackers to disable the appliance firewall. Public advisories identify a hidden firewall-control feature but disclose no request path, command handler, or triggering input. Exposure requires non-VPN Internet access to the management interface; exploitation permits OS command execution or device-configuration changes.
