Description
Cudy TR3000 before 2.5.42 contains a remote code execution vulnerability that allows unauthenticated adjacent attackers to run root commands by advertising a rogue automesh controller over mDNS. Attackers on the upstream Ethernet segment can advertise _cudycmagent._tcp records pointing to a malicious MQTT broker, then send commands encrypted with a fixed AES key that router/batchcmd.lua executes as root.
