Technical Details
The vulnerability arises from a Java deserialization flaw in the JasperReports library, a component integrated into Hitachi Energy’s Asset Suite. Deserialization of untrusted data occurs when the system processes maliciously crafted reports, allowing attackers to execute arbitrary code remotely. This type of vulnerability is particularly dangerous because it can be exploited without authentication, making it a prime target for threat actors seeking to compromise critical infrastructure.
The CVSS vector string for CVE-2025-10492 is:
`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
This indicates:
- Attack Vector (AV): Network (exploitable remotely).
- Attack Complexity (AC): Low (no specialized conditions required).
- Privileges Required (PR): None (no authentication needed).
- User Interaction (UI): None (exploitable without user action).
- Scope (S): Unchanged (impact limited to vulnerable component).
- Impact: High for confidentiality, integrity, and availability.

Impact Assessment
The exploitation of CVE-2025-10492 could have devastating consequences for organizations relying on Hitachi Energy Asset Suite. Given its deployment in the energy sector, successful attacks could lead to:
- Operational disruption: Unauthorized control of asset management systems.
- Data breaches: Theft or manipulation of sensitive operational data.
- Lateral movement: Attackers could pivot to other critical systems within the network.
- Compliance violations: Failure to address the vulnerability may result in regulatory penalties.
The global deployment of Asset Suite amplifies the risk, as threat actors could target organizations worldwide, particularly those in critical infrastructure sectors.

Mitigation Steps
Hitachi Energy has provided the following immediate actions to mitigate the risk:
#### 1. Apply the Vendor Fix
- Upgrade to Asset Suite version 9.8, which addresses the vulnerability.
#### 2. Restrict External Report Loading
- Limit the loading of external custom reports to only those generated by trusted system administrators.
#### 3. General Mitigation Factors
- Isolate control systems: Ensure Asset Suite and other critical systems are not accessible from the internet.
- Segment networks: Use firewalls to separate control system networks from business networks.
- Enforce access controls: Restrict physical and logical access to authorized personnel only.
- Monitor for malicious activity: Implement intrusion detection systems to identify potential exploitation attempts.
- Follow secure practices: Avoid using control systems for internet browsing, email, or instant messaging. Scan removable media for malware before connection.
