CVE-2026-80217Network attack vector

Authenticated OS command execution via hidden enable-mode function

Published Sep 15, 2026 · Updated Sep 15, 2026

Hidden functionality in Lite-On FF-RFI078I4 and FF-RFI079I4 before 02.01.15 allows remote authenticated users to execute OS commands. The SSH enable-mode interface exposes hidden functionality that invokes arbitrary operating-system commands, but the underlying function is undisclosed. Exploitation requires valid SSH login access and permission to enter enable mode, after which commands execute on the O-RU appliance.
