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
A vulnerability in the secure configuration of authentication and management services in Brocade Fabric OS before Fabric OS 9.2.1c2 could allow an authenticated, remote attacker with administrative credentials to execute arbitrary commands as root using “supportsave”, “seccertmgmt”, “configupload” command.

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 · moderate confidence

Command injection vulnerability in Brocade Fabric OS administrative commands (supportsave, seccertmgmt, configupload) allows authenticated remote attackers with admin credentials to execute arbitrary commands as root due to insufficient input validation in these management utilities.

MitigationUpgrade to Fabric OS 9.2.1c2 or later. Restrict administrative access to trusted personnel and monitor for anomalous command execution until the patch is applied.

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. Check Fabric OS version
    Run the 'version' command in the Fabric OS CLI to retrieve the installed firmware version
    Affected if Version is before 9.2.1c2, or is 9.2.2 through any version before 9.2.2b (9.2.2 through 9.2.2a)
  2. Verify admin authentication is enabled
    Confirm that admin accounts exist and admin-level CLI or web management interface is accessible by checking 'admin' account status with 'adminShow' or reviewing authentication configuration
    Affected if Admin credentials are configured and the management interfaces are reachable on the switch
  3. Identify exposure of admin credentials
    Review access controls, user accounts, and whether admin passwords are shared, default, or stored insecurely using 'userConfig --show' or similar user listing commands
    Affected if Any untrusted personnel or systems have admin-level access credentials

Environment is affected if Fabric OS version falls within the vulnerable ranges AND admin credentials can be obtained or are accessible to an attacker.

Upgrade available Upgrade to 9.2.1c2 / 9.2.2b or later
Fixed in 9.2.1c29.2.2b
Interim mitigation

Upgrade to Fabric OS 9.2.1c2 or later. Restrict administrative access to trusted personnel and monitor for anomalous command execution until the patch is applied.

Recommended fix Moderate confidence

Fabric OS 9.2.1c2 or 9.2.2b (or later stable release)

  1. 1. Identify the current Fabric OS version by running 'firmwareshow' or checking the switch boot log.
  2. 2. Schedule a maintenance window for the upgrade process.
  3. 3. Download the fixed Fabric OS release (9.2.1c2 or 9.2.2b or later) from the Broadcom Support Portal at support.broadcom.com.
  4. 4. Verify the firmware integrity using checksums provided on the download page.
  5. 5. Upload the firmware to the Fabric OS switch using 'firmwaredownload' command or Fabric Web Tools.
  6. 6. Confirm the upgrade completes successfully and the switch boots into the fixed version.
  7. 7. Verify the fix by running 'firmwareshow' to confirm the version is >= 9.2.1c2 or >= 9.2.2b.
Caveat Standard Fabric OS upgrade precautions apply - ensure backup of configuration and plan for potential downtime; some older hardware may have limited upgrade path support
