CVE-2023-0580Network attack vector

Application takeover via unprotected credential file

Published Apr 6, 2023 · Updated Feb 10, 2025

Insecure credential storage in ABB MCS-OP 5.0 through 5.13 allows remote authenticated users to access protected application data. The User Interface, System Monitoring, and Asset Inventory services write confidential data to an unprotected file, allowing affected service identities to be impersonated. Low-privileged network access is required; successful impersonation exposes every application database granted to the affected service and permits application control.
