AI-suggested
A fixed firmware version 2.5.42 or later addresses this vulnerability. Users should upgrade their Cudy TR3000 devices to version 2.5.42 or newer to remediate the issue. Until patched, avoid exposing devices to untrusted adjacent networks.
Description
Cudy TR3000 devices running firmware versions before 2.5.42 have a vulnerability in the mt_wifi Smart Mesh Technology onboarding process. The vulnerability arises from insufficient verification of data authenticity, where messages are protected only by an AES-CBC key derived from public values and a CRC32 check. This allows adjacent unauthenticated attackers to forge Smart Mesh Technology messages in Probe Request vendor information elements, carrying attacker-chosen SSIDs and pre-shared keys. As a result, unpaired devices can be forced to join attacker-controlled access points.
