Executive Summary

DEEBOT PRO M1 and DEEBOT PRO K1VAC robots have a flawed authentication algorithm in their Websocket communications. This allows an unauthenticated attacker to connect to and operate the affected devices without needing valid credentials.

Detection Guidance

Detecting this vulnerability requires checking for unauthenticated Websocket connections to DEEBOT PRO M1 or DEEBOT PRO K1VAC devices. Monitor network traffic for unencrypted Websocket connections on standard ports (e.g., 80, 443) and inspect device logs for unusual connection attempts.

Impact Analysis

An attacker could take control of your robot vacuum or mop, potentially using it to access your home network, monitor activities, or cause physical disruption. This could lead to privacy invasion or property damage depending on the robot's capabilities.

Compliance Impact

This vulnerability may violate data protection regulations like GDPR or HIPAA if the robot collects or transmits personal data without proper authentication. Organizations using these devices could face compliance violations and legal penalties.

Mitigation Strategies

Immediately isolate affected devices from the network to prevent unauthorized access. Disable Websocket communications if not required or restrict access via firewall rules. Contact Ecovacs for firmware updates addressing the authentication flaw.
