CVE-2025-10217 is a medium-severity vulnerability identified in Hitachi Energy's Asset Suite version 9.0. The vulnerability is classified under CWE-117, which involves improper output neutralization for logs. Specifically, an authenticated user with low privileges can manipulate or inject crafted data into the performance-related log files. Performance logging in Asset Suite is typically enabled to assist in troubleshooting and resolving application performance issues. However, due to insufficient sanitization or neutralization of log output, malicious actors can insert specially crafted content into log entries. This can potentially facilitate further malicious activities such as log injection attacks, log forging, or evasion of detection mechanisms. The vulnerability does not require user interaction beyond authentication and can be exploited remotely over the network with low attack complexity. The CVSS 4.0 vector indicates no user interaction is needed, privileges required are low, and the impact is high on integrity but none on confidentiality or availability. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability's root cause lies in the failure to properly sanitize log input, allowing attackers to inject arbitrary content into logs, which can mislead administrators, corrupt audit trails, or be leveraged as a stepping stone for further attacks such as command injection or privilege escalation if combined with other vulnerabilities.

For European organizations using Hitachi Energy Asset Suite 9.0, this vulnerability poses a risk primarily to the integrity and reliability of performance logs. Manipulated logs can lead to misdiagnosis of system performance issues, delayed incident response, and potential cover-up of malicious activities. In critical infrastructure sectors such as energy, where Hitachi Energy products are often deployed, compromised logs can undermine operational transparency and forensic investigations. Attackers could exploit this to hide traces of intrusion or escalate attacks, potentially impacting the availability and stability of energy management systems. Given the importance of energy infrastructure in Europe, any disruption or mismanagement caused by corrupted logs could have cascading effects on service delivery and regulatory compliance. Although the vulnerability requires authentication, insider threats or compromised credentials could be leveraged to exploit this flaw. The absence of confidentiality impact reduces the risk of data leakage, but the integrity impact on logs is significant for audit and compliance processes.

European organizations should implement the following specific mitigations: 1) Restrict and monitor access to Asset Suite logging features to minimize the number of authenticated users who can manipulate performance logs. 2) Implement strict input validation and sanitization controls on any user-supplied data that may be logged, even before official patches are available. 3) Employ centralized and tamper-evident logging solutions to detect anomalies or suspicious log entries indicative of injection attempts. 4) Conduct regular audits of log files for signs of manipulation or injection patterns. 5) Use multi-factor authentication and robust credential management to reduce the risk of unauthorized access. 6) Engage with Hitachi Energy support to obtain patches or updates addressing this vulnerability as soon as they are released. 7) Consider temporarily disabling performance logging if feasible, or limit its use to trusted environments until the vulnerability is remediated. 8) Train security and operations teams to recognize and respond to log integrity issues promptly.
