Summary

Hitachi Energy e-mesh EMS contains buffer overflow, use-after-free, or resource exhaustion vulnerabilities (CWE-119, CWE-416, CWE-400) that allow remote, unauthenticated attackers to cause denial-of-service conditions. The vulnerabilities affect e-mesh EMS version 1.0.0. No public exploits are known, but the high EPSS score (89.4%) indicates elevated exploitation risk.

What this means
What could happen
An attacker could trigger a denial-of-service condition on the e-mesh EMS, disrupting energy management and control visibility across your utility's network operations.
Who's at risk
Energy utilities and distributed energy resource operators rely on e-mesh EMS for centralized energy management and monitoring. Any facility using this platform for microgrid control, demand response, or system-wide visibility is affected.
How it could be exploited
An attacker on the network sends crafted packets to the e-mesh EMS on its accessible ports. The vulnerability (buffer overflow, use-after-free, or resource exhaustion) causes the EMS to crash or become unresponsive, halting energy management functions.
Prerequisites
  • Network access to e-mesh EMS service ports
  • No credentials required
  • Device must be reachable from the attacker's network segment
