CVE-2025-8449

Authenticated service interruption via undisclosed endpoint request

Published Aug 20, 2025 · Updated Sep 9, 2025

Uncontrolled resource consumption in Schneider Electric EcoStruxure Building Operation allows remote authenticated users to interrupt service. Schneider Electric identifies a specially crafted request to a specific endpoint but has not disclosed the endpoint, resource, or faulty operation. Reachability requires authenticated access from within the BMS network and passive user interaction; the reported consequence is limited to availability.
