CVE-2025-26856Network attack vector

Authenticated command execution via crafted screen request

Published Feb 20, 2025 · Updated Feb 20, 2025

OS command injection in UD-LT2 firmware 1.00.008_SE and earlier allows remote authenticated users to execute arbitrary commands. A management-screen handler incorporates attacker-controlled request content into an OS command without neutralizing special elements; the vendor has not disclosed the exact screen or parameter. Administrative access to the management interface is required, and successful exploitation grants command execution in the router firmware context.
