CVE-2025-1531 is a vulnerability identified in Hitachi Ops Center Analyzer viewpoint versions from 10.0.0-00 up to but not including 11.0.4-00. The issue is classified under CWE-1392, which corresponds to the use of default credentials. This vulnerability allows an attacker to gain unauthorized access due to the presence of default authentication credentials that are either hardcoded or not properly changed during deployment. The CVSS 3.1 base score is 6.5, indicating a medium severity level. The vector string (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N) shows that the vulnerability is remotely exploitable over the network without requiring privileges or user interaction. The impact affects confidentiality and integrity but not availability. Specifically, an attacker can leak authentication credentials, potentially allowing unauthorized access to sensitive data or system functions within the Hitachi Ops Center Analyzer viewpoint environment. This product is used for storage infrastructure analytics and management, meaning that exploitation could expose operational data or allow manipulation of analytics results. No known exploits are currently reported in the wild, and no patches are linked yet, indicating that organizations should be vigilant and plan for remediation once patches become available.

For European organizations, the impact of this vulnerability can be significant, especially for enterprises relying on Hitachi storage solutions and analytics for critical infrastructure management. Unauthorized access due to default credentials can lead to exposure of sensitive operational data, potentially violating data protection regulations such as GDPR. Integrity compromise could result in falsified analytics or mismanagement of storage resources, affecting business continuity and decision-making. Since the vulnerability does not require user interaction or privileges, it can be exploited by remote attackers, increasing the risk of widespread attacks. Organizations in sectors such as finance, healthcare, telecommunications, and government, which often use enterprise storage analytics tools, may face increased risk of data leakage or operational disruption. Additionally, the lack of availability impact reduces the chance of denial-of-service but does not mitigate the risk of data confidentiality and integrity breaches.

European organizations should immediately audit their deployments of Hitachi Ops Center Analyzer viewpoint to identify affected versions (10.0.0-00 up to before 11.0.4-00). Until patches are released, the following specific mitigations are recommended: 1) Change all default credentials immediately upon installation or upgrade, ensuring strong, unique passwords are used. 2) Restrict network access to the management interfaces of the Ops Center Analyzer viewpoint using firewalls or network segmentation to limit exposure to trusted administrators only. 3) Implement strict monitoring and logging of authentication attempts and access to detect any unauthorized access early. 4) Employ multi-factor authentication (MFA) if supported by the product or via external access control mechanisms. 5) Coordinate with Hitachi support to obtain updates on patch availability and apply security updates promptly once released. 6) Conduct regular vulnerability assessments and penetration testing focused on credential management and authentication controls in the affected environment. These targeted actions go beyond generic advice by focusing on credential hygiene, network controls, and proactive detection tailored to this specific vulnerability.
