Description
Multiple TP-Link Kasa smart home devices contain insufficient cryptographic protections in the local device communication protocol.

Successful exploitation could allow an attacker to manipulate the operational state of an affected device, resulting in unauthorized state changes, disruption of normal device functionality or a denial-of-service condition.
