Description

TP-Link Tapo C210 V3.60 contains an authentication bypass vulnerability in the DS JSON API. A crafted JSON request containing both a protected operation and public onboarding-related fields may cause module-level authorization checks to be applied inconsistently, allowing protected camera operations, including pan-tilt-zoom control, to be executed without a valid authenticated session. Successful exploitation may allow an unauthenticated attacker on the adjacent network to perform protected camera operations, including pan-tilt-zoom (PTZ) control, without a valid authenticated session. This could result in unauthorized manipulation of camera functionality.
