Administrative command execution via crafted screen request

Published Jan 22, 2025 · Updated Feb 20, 2025

OS command injection in UD-LT2 firmware 1.00.008_SE and earlier allows attackers to execute arbitrary operating-system commands. The vendor identifies a request for a management screen as the affected locus but does not disclose the parameter or command construction. Exploitation requires an administrative account and management-interface access and grants command execution with appliance operating-system privileges.
