Credential disclosure via unauthenticated TSKEP peer
Published Aug 22, 2023 · Updated Aug 2, 2024
Improper authentication in affected TP-Link Tapo devices and app 2.8.14 allows physically proximate attackers to obtain account credentials. The app accepts an attacker-controlled AES session key because TSKEP provides no proof that the responding peer is an associated device, then encrypts login and setup secrets to that peer. Exploitation requires proximity to the app's Wi-Fi network and app activity; the disclosed Tapo and Wi-Fi credentials enable account impersonation and local-network access.
