CVE-2024-3982 Hitachi Energy CVE debrief

Who should care

OT/ICS operators, Hitachi Energy MACH GWS administrators, and teams responsible for local host access control and patch management on affected systems.

Technical summary

CISA rates the issue CVSS 3.1 8.2 HIGH with vector AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H. The advisory identifies affected Hitachi Energy MACH GWS versions as 3.0.0.0 to 3.3.0.0. The stated attack path requires local access to the machine running MACH GWS and administrator rights to enable session logging, which is disabled by default. The vendor remediation is to upgrade to 3.4.0.0.

Defensive priority

High. The issue is high-severity and can affect confidentiality, integrity, and availability, but it requires local access and elevated privileges, so remediation should be prioritized for systems where local administrator access is not tightly controlled.

Recommended defensive actions

• Upgrade Hitachi Energy MACH GWS to version 3.4.0.0 as recommended in the advisory.
• Restrict local and administrator access to MACH GWS hosts, since the described attack path depends on host access and admin privileges.
• Keep session logging disabled unless operationally required, and follow Hitachi Energy and CISA ICS defense-in-depth guidance for industrial control systems.
