CVE-2024-35295

Configuration tampering via unauthenticated maintenance port

Published Jun 11, 2025 · Updated Jun 12, 2025

Missing authentication in Innomotics Perfect Harmony GH180 8.0 through versions before 8.3.3 allows attackers to alter configuration. The maintenance connection exposes control-unit configuration changes through its door port without authenticating the connected party. Physical access to the door port on an NXGPro+ controller manufactured from April 2020 through April 2025 is required, and arbitrary changes compromise configuration integrity and drive availability.
