- CWE-325 - Missing Cryptographic Step
Summary
Multiple
TP-Link Kasa smart home devices contain insufficient cryptographic protections
in the local device communication protocol. An adjacent network attacker may
intercept, replay or forge locally exchanged control messages, potentially
resulting in unauthorized device control.
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.
