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 · unedited
Dell PowerScale OneFS versions prior to 9.13.0.0 contains an improper restriction of excessive authentication attempts vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access.

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 confidence

Dell PowerScale OneFS versions prior to 9.13.0.0 fail to properly restrict excessive authentication attempts, allowing unauthenticated remote attackers to perform unlimited login attempts (brute force/password spray) without account lockout or rate limiting, potentially leading to unauthorized access to the system.

MitigationUpgrade Dell PowerScale OneFS to version 9.13.0.0 or later to obtain the patch that implements proper authentication attempt restrictions.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed PowerScale OneFS version
    Run the OneFS CLI command to display the current firmware version (commonly 'isi version' or check through the web administration interface under System > Overview)
    Affected if The displayed version is any release prior to 9.13.0.0 (for example 9.12.x, 9.11.x, earlier releases)
  2. Verify account lockout policy configuration
    Access the OneFS authentication settings through the web UI (Platform API or isi command line) and examine the account lockout parameters that control how many failed attempts trigger a lockout
    Affected if No account lockout policy is defined, or the lockout threshold is set to zero (unlimited attempts allowed) or is missing entirely
  3. Confirm authentication rate limiting is enabled
    Review the authentication rate limiting or throttling configuration in OneFS settings (typically found under Security > Authentication or via the isi auth settings CLI)
    Affected if Rate limiting is disabled, not configured, or set to allow unlimited authentication attempts per time window
  4. Inspect authentication logs for brute force activity
    Examine OneFS audit or authentication logs (via 'isi audit' or the logs directory) for evidence of repeated failed login attempts from the same source without triggering any blocks
    Affected if Logs show many failed authentication attempts from a single source without any account lockout or rate limit intervention occurring

Your environment is affected if the installed OneFS version is below 9.13.0.0 AND no account lockout or rate limiting controls are actively enforced in the authentication configuration.

Upgrade available Upgrade to 9.13.0.0 or later
Fixed in 9.13.0.0
Interim mitigation

Upgrade Dell PowerScale OneFS to version 9.13.0.0 or later to obtain the patch that implements proper authentication attempt restrictions.

Recommended fix High confidence

OneFS 9.13.0.0

  1. Back up the current OneFS configuration and critical data before proceeding with the upgrade
  2. Download the OneFS 9.13.0.0 update package from Dell Technologies support website
  3. Access the PowerScale OneFS web administration interface or use the CLI (isi升级) to initiate the upgrade
  4. Follow the on-screen prompts or use the 'isi升级 -a' command to apply the OneFS 9.13.0.0 update
  5. Allow the system to complete the upgrade process and automatically reboot as needed
  6. After the system restarts, verify the OneFS version is 9.13.0.0 or later using 'isi version' or the web UI
  7. Confirm the authentication mechanism is functioning correctly and the vulnerability is remediated
Caveat Standard OneFS upgrade best practices apply; ensure compatibility with existing integrations and test in non-production environment first
