CVE-2026-58457

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.

Summary		(es) El Repetidor Wi-Fi Shenzhen Aitemi M300 (modelo de hardware MT02) contiene una vulnerabilidad de inyección de comandos del sistema operativo no autenticada que permite a atacantes adyacentes a la red ejecutar comandos de shell arbitrarios inyectando entrada no saneada a través del gestor smacfilter_conf en el backend web de commuos. Los atacantes pueden añadir cargas útiles delimitadas por punto y coma a los parámetros GET name, enable o mac, los cuales se pasan sin saneamiento a sprintf() para construir comandos de shell uci ejecutados a través de doSystemCmdComlib(), otorgando control total a nivel de root del dispositivo.
