CVE-2025-41452Network attack vector

Authenticated service interruption via Nginx configuration injection

Published Aug 22, 2025 · Updated Aug 22, 2025

Configuration injection in Danfoss AK-SM 8xxA Series before 4.3.1 allows remote authenticated users to interrupt service. The system web interface accepts authenticated configuration input for Nginx and applies exceptional values without safe handling, placing the web service into a denial-of-service condition. A privileged authenticated web session and additional user action are required; the disclosed consequence is service interruption rather than data access or modification.
