Summary
by MITRE • 07/07/2025
IBM Storage Virtualize 8.5, 8.6, and 8.7 products could allow a user to escalate their privileges to that of another user logging in at the same time due to a race condition in the login function.

The vulnerability identified as CVE-2025-1351 affects IBM Storage Virtualize versions 8.5, 8.6, and 8.7, presenting a critical privilege escalation risk through a race condition in the authentication mechanism. This flaw specifically impacts the login function where concurrent user sessions can create an exploitable timing window that allows an authenticated user to potentially assume the identity of another user who is simultaneously logging in. The race condition arises from insufficient synchronization mechanisms during the authentication process, enabling malicious actors to manipulate session handling and gain unauthorized access to other user accounts.
The technical implementation of this vulnerability stems from inadequate thread safety measures within the authentication subsystem of IBM Storage Virtualize. When multiple users attempt to log in simultaneously, the system fails to properly manage shared resources and session state variables, creating opportunities for race conditions to occur. This type of vulnerability is classified as CWE-362, which specifically addresses Race Conditions in software systems where multiple threads or processes access shared data concurrently without proper synchronization. The flaw manifests when the system's login function does not adequately validate session states or when session identifiers are not properly isolated between concurrent authentication attempts, allowing one user's authentication context to interfere with another's.
From an operational perspective, this vulnerability poses significant risk to enterprise storage environments where multiple administrators or users may be accessing the same storage system simultaneously. The impact extends beyond simple privilege escalation as it can enable attackers to access sensitive storage configurations, modify data access controls, or potentially gain access to confidential storage resources that should be restricted to specific authorized users. The vulnerability's exploitation requires concurrent login activity, making it particularly concerning in environments where multiple administrators regularly access storage systems during maintenance windows or routine operations. This creates a realistic attack scenario where an attacker can observe and exploit the timing window between login initiation and session validation to hijack active user sessions.
The security implications of CVE-2025-1351 align with ATT&CK technique T1078.004 which covers Valid Accounts - Cloud Accounts, as the vulnerability enables unauthorized access through legitimate user credentials. Organizations using IBM Storage Virtualize products should immediately implement mitigations including applying the latest security patches from IBM, implementing additional authentication controls, and monitoring for suspicious concurrent login patterns. Network segmentation and access controls should be strengthened to limit exposure, while security teams should establish alerting mechanisms for multiple simultaneous login attempts to detect potential exploitation attempts. The vulnerability underscores the critical importance of proper concurrency control in authentication systems and highlights the need for comprehensive security testing of session management components in enterprise storage solutions.
