The record
Cudy WR3000 2.0 running firmware before 2.5.24 contains an OS command injection vulnerability that allows authenticated attackers to execute arbitrary OS commands with root privileges by sending unsanitized input through the mesh MQTT command interface. The sync_command binary forwards unsanitized input directly to a shell execution sink in command.lua, enabling attackers with access to the MQTT broker to exploit the default-enabled command execution path to achieve full root-level system compromise.
