CVE-2025-1351 is a medium-severity vulnerability affecting IBM Storage Virtualize versions 8.5, 8.6, and 8.7. The vulnerability arises from a race condition (CWE-362) in the login function, where concurrent execution using a shared resource is improperly synchronized. This flaw allows a user who is logging in concurrently with another user to escalate their privileges to those of the other user. Specifically, the race condition occurs during the authentication process, enabling an attacker with low privileges and requiring user interaction to potentially gain high-privilege access. The CVSS 3.1 base score is 6.7, reflecting the complexity of the attack (high attack complexity), the need for local access (local attack vector), and user interaction. The vulnerability impacts confidentiality, integrity, and availability, as an attacker can gain unauthorized access and potentially disrupt or manipulate storage resources. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that mitigation may require close monitoring of IBM advisories. The vulnerability is particularly critical in environments where IBM Storage Virtualize is used to manage sensitive or critical storage infrastructure, as unauthorized privilege escalation could lead to data breaches or service disruption.

For European organizations, this vulnerability poses a significant risk, especially for enterprises relying on IBM Storage Virtualize for critical storage infrastructure. Unauthorized privilege escalation could lead to data confidentiality breaches, unauthorized data modification, or denial of service through manipulation of storage resources. Given the importance of data protection under regulations such as GDPR, any compromise of storage systems could result in regulatory penalties and reputational damage. Organizations in sectors such as finance, healthcare, telecommunications, and government, which often use IBM storage solutions, could face operational disruptions and data integrity issues. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, particularly in environments with multiple users or shared access. The lack of known exploits suggests that proactive mitigation is essential to prevent future exploitation.

European organizations should implement the following specific mitigations: 1) Restrict and monitor local access to IBM Storage Virtualize systems, ensuring only authorized personnel can log in concurrently. 2) Enforce strict session management policies to prevent simultaneous logins that could trigger the race condition. 3) Apply principle of least privilege to limit user permissions, reducing the impact of any privilege escalation. 4) Monitor login activities and audit logs for unusual concurrent login patterns or privilege escalations. 5) Engage with IBM support to obtain patches or workarounds as soon as they become available and prioritize timely deployment. 6) Consider network segmentation and access controls to isolate storage management interfaces from general user networks. 7) Educate users about the risks of concurrent logins and enforce policies to minimize risky login behaviors. These targeted measures go beyond generic advice by focusing on the specific concurrency and login context of the vulnerability.
