CVE-2024-46549Public exploitNetwork attack vector

Cross-device property modification via inconsistent device identity

Published Sep 30, 2024 · Updated Sep 30, 2024

Improper privilege management in TP-Link Kasa KP125M 1.0.3 allows remote authenticated users to alter other devices' cloud properties. The /common/v1/uploadDeviceInfo API checks the deviceId and deviceToken parameters but accepts a different deviceId in the request body. Remote authenticated users need a legitimate device connection to the MQTT broker; forged properties can block the owner's mobile-app access without damaging the plug.
