CVE-2024-3313

Local code execution through outdated third-party libraries

Published Apr 9, 2024 · Updated Aug 1, 2024

Outdated components in SUBNET PowerSYSTEM Server and Substation Server 2021 before 4.07.00 allow local users to execute arbitrary code. The products load vulnerable third-party libraries, but SUBNET and CISA have not identified the libraries, code paths, or triggering input. Exploitation requires local access but no privileges or user interaction and also enables privilege escalation or service interruption.
