CVE-2023-34829Public exploit

Adjacent credential theft via forged device handshake

Published Dec 28, 2023 · Updated Apr 17, 2025

Cleartext credential disclosure in TP-Link Tapo before 3.1.315 allows attackers to obtain an app user's password. The app trusts a forged UDP discovery response, negotiates an attacker-chosen AES key over HTTP, and sends credentials encrypted under that key. The attacker must share the local network and either know the account email address or derive its identifier from a TP-Link device; opening the app then exposes the password without affecting integrity or availability.
