CVE-2023-43775

Adjacent-network automation-platform restart

Published Sep 26, 2023 · Updated Sep 24, 2024

Denial of service in Eaton SMP Gateway web servers allows adjacent-network attackers to force an unexpected platform restart. Eaton identifies uncontrolled resource consumption in the web server but has not published the request pattern, consumed resource, or faulty operation. No authentication or user interaction is required; rare restarts enter Safe Mode or Max Safe Mode, while remote maintenance access remains available.
