Until an official fix is available, restrict network access to the device's management interface to trusted users only and monitor for suspicious activity. Avoid exposing the device's web backend to untrusted networks.
Description
Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02) contains an unauthenticated OS command injection vulnerability that allows network-adjacent attackers to execute arbitrary shell commands by injecting unsanitized input through the smacfilter_conf handler in the commuos web backend. Attackers can append semicolon-delimited payloads to the name, enable, or mac GET parameters, which are passed without sanitization into sprintf() to build uci shell commands executed via doSystemCmdComlib(), granting full root-level control of the device.
