Who should care

Organizations running Hitachi Energy Service Suite versions 9.8.1.3 or below, especially industrial control system and OT environments that may expose the service to reachable networks.

Technical summary

The advisory identifies Apache HTTP Server 2.4 vulnerabilities in Hitachi Energy Service Suite. The CVSS v3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N, which means a network-reachable issue with no required privileges or user interaction and a primary impact to integrity. The source corpus does not provide exploit details or a more specific vulnerability class beyond the Apache HTTP Server 2.4 reference.

Defensive priority

High. The issue is remotely reachable, requires no authentication or user interaction, and affects a product used in OT/ICS contexts. The vendor remediation is straightforward, but any exposed or operationally critical deployment should be prioritized for inventory, containment, and patching.

Recommended defensive actions

  • Update Hitachi Energy Service Suite to version 9.8.1.4 as directed by the vendor.
  • Inventory all Service Suite deployments and confirm whether any instance is at version 9.8.1.3 or below.
  • Restrict network access to the service to only necessary management and operational hosts.
  • Review exposure of any externally reachable or broadly reachable OT/ICS management interfaces.
  • Monitor affected environments for unexpected configuration or integrity changes while remediation is planned and completed.

Evidence notes

CISA’s CSAF advisory ICSA-25-133-01 lists Hitachi Energy Service Suite versions 9.8.1.3 and below as affected, describes the issue as Apache HTTP Server 2.4 vulnerabilities, and recommends updating to 9.8.1.4. The advisory’s CVSS vector is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N, supporting the HIGH severity and integrity-focused impact. No KEV listing is present in the supplied data.
