Description
Cudy TR3000 before 2.5.42 contains an insufficient verification of data authenticity vulnerability in the mt_wifi Smart Mesh Technology (SMT) onboarding, which protects messages only with an AES-CBC key derived from public values and a CRC32 check. Adjacent unauthenticated attackers can forge SMT messages in Probe Request vendor IEs carrying an attacker-chosen SSID and pre-shared key, forcing unpaired devices to join attacker-controlled access points.
