Vulnerability details

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…

more

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.

Why these techniques?

Unauthenticated command injection in web backend directly enables exploitation of public-facing app (T1190) for arbitrary Unix shell execution (T1059.004).

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Requires validation and sanitization of the name, enable, and mac GET parameters before they are passed to sprintf() and doSystemCmdComlib().

AC-3 Access Enforcement good match
prevent

Enforces authentication and authorization on the commuos web backend so that unauthenticated network-adjacent actors cannot invoke smacfilter_conf.

CM-7 Least Functionality partial match
prevent

Restricts the device to only the minimum required functions, disabling or removing the vulnerable smacfilter_conf handler and doSystemCmdComlib() capability.
