Estado: ModificadaCrítica (9.8)—

Grandstream UCM6200 series firmware version 1.0.20.23 and below is vulnerable to OS command injection via HTTP. An authenticated remote attacker can bypass command injection mitigations and execute commands as the root user by sending a crafted HTTP POST to the UCM's "New" HTTPS API.
