## Overview

Tapo C320WS
V2.0 contains an authenticated stack-based buffer overflow in the local
onboarding Wi-Fi configuration path. An authenticated attacker on the
adjacent network can submit a crafted request containing an oversized encrypted
password field, overwrite stack state, and execute commands with root
privileges.





Successful
exploitation may allow an authenticated adjacent-network attacker to take
control of the affected camera, modify camera behavior, access sensitive local
configuration, and disrupt device availability.
