Summary

Hitachi Energy MSM contains vulnerabilities (CWE-772 resource leaks, CWE-835 infinite loops) that could allow an attacker to impact confidentiality, integrity, or availability of the system. MSM is a monitoring and management platform for energy infrastructure. The vulnerabilities affect versions 2.2.8 and earlier. No patch is currently available from Hitachi Energy.

What this means
What could happen
An attacker with network access to MSM could trigger resource exhaustion or system hangs, potentially causing the monitoring system to become unavailable and preventing visibility into critical energy infrastructure operations.
Who's at risk
Energy sector organizations operating Hitachi Energy MSM systems for monitoring and controlling power generation, transmission, and distribution equipment should take action. This includes utilities using MSM for SCADA monitoring, grid management, and real-time system visibility.
How it could be exploited
An attacker with network access to the MSM server could send malformed requests that trigger resource leaks or infinite loops in the application, causing the system to exhaust memory or CPU and become unresponsive. Exploitation does not appear to require authentication based on the advisory details.
