CVE-2023-28388 Hitachi Energy CVE debrief

Who should care

OT asset owners, control-system operators, maintenance engineers, and integrators responsible for Hitachi Energy MACH PS700 v2 System deployments should review this advisory. IT teams should also care if endpoint software inventory shows the referenced Intel chipset driver/software on systems that support or administer the affected environment.

Technical summary

The advisory maps CVE-2023-28388 to Hitachi Energy MACH PS700 v2 System and cites an uncontrolled search path element in Intel(R) Chipset Device Software before version 10.1.19444.8378. The stated impact is local privilege escalation by an authenticated user via local access. CISA lists the CVSS vector as AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H, which aligns with a lower-likelihood but high-impact local attack path.

Defensive priority

Medium priority. The issue is locally exploitable and requires authentication/local access, but it can still matter in OT environments where shared workstations, maintenance laptops, or administrative sessions can provide the needed foothold. Prioritize if the affected product is deployed in sensitive or hard-to-monitor environments.

Recommended defensive actions

• Confirm whether MACH PS700 v2 System is present in your environment and whether the referenced Intel chipset software version is installed.
• Apply the vendor-provided patch scripts or remove the vulnerable software as directed in the advisory.
• Review local-account and administrative access paths on affected hosts to reduce the chance that an authenticated local user can reach the vulnerable component.
• Limit interactive access to engineering and maintenance systems and monitor for unusual privilege escalation activity on endpoints that support the affected product.
• Coordinate remediation with Hitachi Energy/local account teams before making changes in operational technology environments, especially where downtime or configuration constraints apply.
