Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A command injection vulnerability affects the Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02) during WPA2 configuration. The 'key' parameter is interpreted directly by the system shell, enabling attackers to execute arbitrary commands as root. Exploitation requires no authentication and can be triggered during wireless setup.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Command injection in the Shenzhen Aitemi M300 Wi-Fi Repeater (MT02) allows unauthenticated attackers to execute arbitrary commands as root via the 'key' parameter during WPA2 wireless configuration, which is directly interpreted by the system shell without sanitization.

MitigationIsolate affected devices on restricted network segments, monitor for indicators of compromise, and replace or restrict access to these devices until a vendor firmware patch is available.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the device web interface (typically 192.168.1.1 or 192.168.0.1) and check the device information page, or physically inspect the device label for 'Shenzhen Aitemi M300' or 'MT02' model markings
    Affected if The device is a Shenzhen Aitemi M300 Wi-Fi Repeater (MT02)
  2. Check if the web management interface is accessible
    Attempt to access the device HTTP/HTTPS web interface on common management ports. The vulnerable configuration is accessible through the wireless setup or WPA2 settings page
    Affected if The web interface is exposed and accepts wireless configuration parameters including a 'key' parameter for WPA2 passphrase
  3. Verify the 'key' parameter accepts special characters
    Submit a test wireless configuration with a 'key' value containing shell metacharacters such as $(whoami) or ;ls. Observe if the device processes these characters or returns an error indicating command injection potential
    Affected if The 'key' parameter does not sanitize shell metacharacters and appears to pass input directly to system shell execution
  4. Check network exposure of the device
    Determine if the device web management interface is accessible from untrusted network segments by scanning for open HTTP ports (80, 443, 8080) on the device IP address
    Affected if The device management interface is accessible from outside isolated network segments without authentication barriers

The environment is affected if a Shenzhen Aitemi M300 Wi-Fi Repeater (MT02) device with an accessible web interface exists on the network, where the WPA2 'key' parameter in wireless configuration accepts unsanitized input that could be interpreted by the system shell.
