CVE-2025-1351
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIBM Storage Virtualize versions 8.5, 8.6, and 8.7 contain a race condition vulnerability in the login authentication function. An authenticated user can exploit timing window during concurrent login attempts to escalate their privileges to match those of another user logging in simultaneously.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed IBM Storage Virtualize versionRun the command to display the IBM Storage Virtualize system version, typically via the management interface or CLI command such as 'lsversion' or through the system management consoleAffected if The installed version matches 8.5, 8.6, or 8.7 exactly
-
Verify if multiple simultaneous authentication sessions are permittedCheck the system configuration for concurrent session limits or session concurrency settings in the authentication/authorization policyAffected if Concurrent authentication sessions are allowed without strict session isolation controls
-
Confirm user authentication is activeReview the list of currently authenticated users or recent authentication events in the system logsAffected if Multiple users can authenticate to the system simultaneously
-
Inspect authentication logs for concurrent login patternsExamine authentication and audit logs for timestamp proximity between login events that could indicate concurrent login attemptsAffected if Logs show multiple login attempts occurring within a narrow time window (timing window for race condition)
-
Check for privilege escalation indicatorsReview user privilege assignments and session audits to detect if any user sessions have acquired privileges beyond their assigned roleAffected if Users have been granted privileges that do not match their defined role, suggesting successful exploitation
Your environment is affected if IBM Storage Virtualize version 8.5, 8.6, or 8.7 is installed AND concurrent authentication sessions are possible, allowing a race condition timing window to exist.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply IBM-provided patches or upgrades to IBM Storage Virtualize. If no patch is available, monitor authentication logs for suspicious concurrent login patterns and consider restricting simultaneous administrative sessions.
Contact IBM Support for the specific fixed version/PTF (versions 8.5.x, 8.6.x, or 8.7.x after the security fix)
- 1. Log in to IBM Support Portal at www.ibm.com/support and search for IBM Storage Virtualize security bulletins
- 2. Locate the security bulletin for CVE-2025-1351 to identify the specific interim fix (PTF) or fixed version
- 3. Contact IBM Storage Support to obtain the appropriate fix for your current version (8.5, 8.6, or 8.7)
- 4. Schedule a maintenance window following IBM's recommended upgrade/patch procedures
- 5. Apply the fix following IBM's standard Storage Virtualize maintenance procedures
- 6. Verify the fix was applied successfully by checking the system version and confirming the patch is loaded
