Title
Unauthenticated Onboarding Scan Information Disclosure in TP-Link Tapo C120 & C200
Summary
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.
