CVE-2024-47133Known exploitationNetwork attack vector

Arbitrary OS command execution via command injection

Published Dec 5, 2024 · Updated Dec 18, 2024

OS command injection in UD-LT1 and UD-LT1/EX firmware 2.1.9 and earlier allows remote authenticated users to run arbitrary commands. The vendor has not disclosed the affected interface, parameter, or faulty operation that passes attacker-controlled input to an OS command. An administrative account is required; successful exploitation grants command execution with the router process privileges, enabling device data access, configuration changes, or service interruption.
