Hitachi Energy Service Suite
Act Now9.8ICS-CERT ICSA-25-133-01May 13, 2025
Summary
Hitachi Energy Service Suite versions 9.8.1.3 and earlier contain multiple vulnerabilities including buffer overflows (CWE-787), integer overflows (CWE-190), input validation flaws (CWE-444), and denial-of-service conditions (CWE-770, CWE-400). These flaws allow remote code execution, data manipulation, information disclosure, and service disruption without authentication. The vulnerabilities stem from improper handling of network requests and memory management. Hitachi Energy has released version 9.8.1.4 as a fix.
What this means
What could happen
Multiple vulnerabilities in Hitachi Energy Service Suite could allow an attacker to execute code, modify data, or disrupt availability of the platform. This could compromise energy asset management, reporting, and control functions that operators depend on.
Who's at risk
Energy sector operators relying on Hitachi Energy Service Suite for asset management, configuration, and reporting should prioritize this vulnerability. Service Suite versions 9.8.1.3 and earlier running on engineering workstations or central servers are at risk. This affects utilities that use Service Suite for managing distribution equipment, substations, or control system configuration.
How it could be exploited
An attacker with network access to the Service Suite could send specially crafted requests exploiting buffer overflow, integer overflow, or input validation flaws. These vulnerabilities allow remote code execution and data corruption without authentication required.
Prerequisites
- Network access to Service Suite on affected version 9.8.1.3 or earlier
- No authentication or credentials required
- Ability to send malformed HTTP/API requests to the platform
