What it is

Tapo C120 v1 and C200 V5

contain a vulnerability in the HTTPS onboarding scan function due to missing authentication.

After initial setup, an unauthenticated attacker on the same local network can

invoke the scan action and retrieve nearby wireless access-point metadata,

including SSIDs, BSSIDs, authentication and encryption modes, and

signal-strength information.

Successful

exploitation may disclose information about the wireless environment

surrounding the camera, allowing an attacker to learn elements of the local

wireless topology.
