description

Tenda W18E devices expose an OS command injection flaw in the web management server's packet-capture diagnostic feature. An authenticated attacker can cause commands to run with root privileges; a device still in its factory-reset state may allow exploitation without authentication.

mitigation

Restrict web management access to trusted administrative networks and do not expose factory-reset devices to untrusted networks; complete initial setup and set administrator credentials promptly. No fixed firmware version is recorded, so monitor vendor support for an updated release.
