CVE-2025-10217 is a vulnerability classified under CWE-117 (Improper Output Neutralization for Logs) affecting Hitachi Energy's Asset Suite version 9.0. The flaw allows an authenticated user with low privileges to manipulate performance-related log data or inject crafted entries into log files. Performance logging is typically enabled to assist in troubleshooting application performance issues. However, the vulnerability stems from insufficient sanitization or neutralization of log inputs, enabling malicious actors to insert specially crafted data into logs. This can lead to log injection attacks, potentially allowing attackers to obscure their activities, mislead administrators, or facilitate further exploitation such as code injection or privilege escalation through log-based attack vectors. The CVSS 4.0 score is 6.0 (medium severity), reflecting network attack vector, low attack complexity, partial authentication required, no user interaction, and high impact on integrity of logs. No known exploits have been reported in the wild, but the vulnerability's presence in critical energy asset management software makes it a concern. The lack of a patch at the time of disclosure means organizations must rely on mitigation strategies until updates are available.

For European organizations, especially those in the energy sector or critical infrastructure using Hitachi Energy Asset Suite 9.0, this vulnerability could compromise the integrity and reliability of performance logs. Manipulated logs can hinder incident detection and response, allowing attackers to hide malicious activities or mislead forensic investigations. This undermines trust in monitoring systems and may delay remediation efforts. Additionally, crafted log entries could be leveraged as a stepping stone for further attacks, including privilege escalation or injection attacks if log data is parsed by other systems. The impact is particularly significant for organizations subject to strict regulatory compliance and audit requirements, such as those governed by NIS2 Directive or GDPR, where log integrity is crucial. Operational disruptions or security incidents resulting from this vulnerability could have cascading effects on energy delivery and infrastructure stability.

Organizations should implement strict access controls to limit who can authenticate and access performance logging features within Asset Suite. Monitoring and alerting on unusual log entries or patterns can help detect potential log manipulation attempts. Until a vendor patch is available, consider disabling performance logging if not essential or restricting it to trusted administrators. Employ log integrity verification mechanisms such as cryptographic signing or centralized log management solutions that can detect tampering. Regularly review and audit logs for anomalies. Coordinate with Hitachi Energy to obtain patches or updates as soon as they are released. Additionally, educate administrators about the risks of log injection and ensure secure coding practices are followed in custom integrations or scripts that consume log data.
