CVE-2025-2514
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.

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 confidenceThis is an improper restriction of excessive authentication attempts vulnerability in Hitachi Virtual Storage Platform systems. The issue allows attackers to make unlimited authentication attempts without adequate lockout, rate limiting, or account takeover protections, enabling brute-force attacks against login interfaces.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 your VSP modelAccess the storage system management interface or use the vendor's command-line interface to retrieve the system model identifier. Common methods include the Hitachi Storage Navigator, GUM (Global Unified Manager), or EMS interface.Affected if The model is one of: VSP E1090h, E790h, E590h, E390h, E1090, E990, E790, or E590.
-
Retrieve the firmware versionCheck the installed firmware version through the management interface or CLI. This is typically found in system information, version details, or DKCMAIN firmware version display.Affected if The firmware version matches any of the affected models listed, as all versions of these models are vulnerable.
-
Verify management interface network exposureExamine network configuration to determine if the management interface (typically accessed via GUI or CLI) is reachable from untrusted networks. Check firewall rules, network zoning, or ACLs protecting the management ports.Affected if The management interface is accessible from networks outside the trusted administrative zone, enabling external brute-force attacks.
-
Inspect authentication security settingsReview the storage system's security or authentication configuration settings for account lockout policies, password attempt limits, or rate limiting features. This may be found in user management, security policies, or login configuration screens.Affected if No account lockout, password attempt limits, or rate limiting is configured for authentication attempts.
-
Review authentication logs for brute-force patternsExamine system authentication logs, audit logs, or security event logs for repeated failed login attempts from the same source IP address or pattern of systematic authentication failures.Affected if Logs show evidence of multiple failed login attempts without account lockout triggering.
You are affected if your system is any VSP E series model (E1090h, E790h, E590h, E390h, E1090, E990, E790, E590) and your management interface is network-accessible from untrusted networks.
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 vendor-provided firmware/software updates to the specified fixed versions (DKCMAIN, GUM, EMS) for your model. As a temporary measure, implement network-level access controls to limit exposure to the management interface and monitor for brute-force patterns.
DKCMAIN Ver A3-04-02-xx/00 or later (E390/E590/E790/E990/E1090); DKCMAIN Ver A3-03-41-xx/00 or later (E390H/E590H/E790H/E1090H)
- Contact Hitachi support or visit the official Hitachi support portal to obtain the firmware update
- Request the specific firmware version for your model: DKCMAIN Ver A3-04-02-xx/00 or later for E390/E590/E790/E990/E1090, DKCMAIN Ver A3-03-41-xx/00 or later for E390H/E590H/E790H/E1090H
- Schedule a maintenance window for the firmware update following Hitachi's recommended procedures
- Apply the firmware update to the affected Virtual Storage Platform device
- After update, verify the firmware version matches or exceeds the fixed version numbers
- Confirm the authentication mechanism now properly restricts excessive authentication attempts
