CVE-2025-59886Network attack vector

Authenticated privileged command execution via endpoint validation failure

Published Dec 23, 2025 · Updated Dec 23, 2025

Improper input validation in the Eaton xComfort ECI web interface in all versions allows remote authenticated users to execute privileged commands. The endpoint fails to validate request input before privileged commands are executed; Eaton has not identified the endpoint, field, or rejected-value checks. Network access and low-privilege authentication are required; published evidence confines the resulting command privileges to the ECI device.
