HighCVSS 8.7
Published: Updated: Translated: NVD NIST

Exploitation Probability (EPSS)

Low risk
0.15%

4th percentile - higher than 4% of all known CVEs

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.

Risk Assessment

The risk includes unauthorized control of devices, which could lead to privacy breaches, disruption of operations, or DoS attacks.

Recommendation

Update TP-Link Kasa device firmware to the latest versions and limit trust in the local network, e.g., by network segmentation.
