CVE-2024-3980 Hitachi Energy CVE debrief

Who should care

Organizations operating Hitachi Energy MACH GWS, especially OT/ICS teams, administrators, and security staff responsible for version tracking, patching, and access control. Any environment running affected versions should treat this as a high-priority remediation item.

Technical summary

The advisory describes an authenticated input handling issue in MACH GWS filesystem operations: user-controlled values can influence path or filename selection. The result, if exploited, is unauthorized access to or modification of sensitive files. CISA’s CSAF lists affected products as MACH GWS version 2.1.0.0 and versions 2.2.0.0 to 2.4.0.0 and 3.0.0.0 to 3.3.0.0. The CVSS v3.1 vector is AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H, scoring 9.9.

Defensive priority

Urgent. This is a network-reachable, authenticated vulnerability with high confidentiality, integrity, and availability impact in an industrial product. Prioritize patching and compensating controls before routine maintenance cycles.

Recommended defensive actions

• Upgrade MACH GWS version 3.0.0.0 through 3.3.0.0 to 3.4.0.0.
• For MACH GWS version 2.1.0.0, apply patches HF1 through HF6 sequentially as directed by the vendor.
• For MACH GWS versions 2.2.0.0 through 2.4.0.0, apply patches HF3 through HF6 sequentially as directed by the vendor.
• If upgrades or sequential patches are not immediately feasible, contact the local account team for vendor-provided mitigation guidance.
• Restrict access to authenticated accounts and review which users can reach MACH GWS management functions.
• Monitor for unexpected file access or modification activity in and around the MACH GWS installation path.
• Validate remediation against the vendor advisory and record the affected version in asset inventory for future patch tracking.

Evidence notes

All factual claims are drawn from the supplied CISA CSAF source item and its referenced Hitachi Energy advisory. The source lists the affected versions, states that authenticated user input can influence file paths or file names used in filesystem operations, and recommends version-specific fixes or sequential hotfixes. The advisory publication date used here is 2025-02-25, matching the supplied CVE and source metadata.
