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 privilege escalation vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, 8.2.0cbn5, could allow a local authenticated user to escalate its privilege to root using switch commands “supportlink”, “firmwaredownload”, “portcfgupload, license, and “fosexec”.

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

A local privilege escalation vulnerability in Brocade Fabric OS CLI allows authenticated users to gain root privileges by abusing specific privileged commands (supportlink, firmwaredownload, portcfgupload, license, and fosexec). The vulnerability affects versions prior to v9.1.0, 9.0.1e, 8.2.3c, and 8.2.0cbn5.

MitigationUpgrade Brocade Fabric OS to version 9.1.0 or later (or the appropriate patched version for your branch: 9.0.1e, 8.2.3c, or 8.2.0cbn5). Restrict CLI access to trusted personnel and follow least-privilege principles until patching is complete.

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 the Fabric OS version
    Access the Fabric OS CLI and run the appropriate command to display the system version (such as 'version' or a similar version-displaying command). Record the exact version number shown.
    Affected if The installed version is 8.0.0 or higher but lower than 8.2.3c, or 9.0.0 or higher but lower than 9.0.1e
  2. Confirm user access to privileged commands
    Query the system to determine if your user account has permission to execute the following privileged commands: supportlink, firmwaredownload, portcfgupload, license, and fosexec. This may be visible in role definitions, permission lists, or by attempting to access help for these commands.
    Affected if Your user account has access to one or more of these five privileged commands (supportlink, firmwaredownload, portcfgupload, license, or fosexec)
  3. Verify user role and privilege level
    Check the current user session role or privilege level using CLI commands that display user permissions or role assignments.
    Affected if Your account holds any administrative, root, or elevated privileges within the Fabric OS CLI

You are affected if the Fabric OS version is within the vulnerable ranges (8.0.0 to below 8.2.3c, or 9.0.0 to below 9.0.1e) AND your user account has access to the vulnerable privileged commands.

Generated from the published advisory. Verify against your own configuration.

Upgrade available Upgrade to 8.2.3c / 9.0.1e or later
Fixed in 8.2.3c9.0.1e
Interim mitigation

Upgrade Brocade Fabric OS to version 9.1.0 or later (or the appropriate patched version for your branch: 9.0.1e, 8.2.3c, or 8.2.0cbn5). Restrict CLI access to trusted personnel and follow least-privilege principles until patching is complete.

Recommended fix High confidence

Fabric OS 9.1.0 or later (or 8.2.3c/8.2.0cbn5 for respective 8.x branches)

  1. 1. Identify the current Fabric OS version by running 'firmwareShow' or 'version' command in the CLI
  2. 2. For Fabric OS 8.x versions (>=8.0.0, <8.2.3c): Plan upgrade to version 8.2.3c or later
  3. 3. For Fabric OS 9.0.x versions (>=9.0.0, <9.0.1e): Plan upgrade to version 9.0.1e or later
  4. 4. For all versions: Plan upgrade to version 9.1.0 or later for the most complete fix
  5. 5. Schedule a maintenance window as firmware upgrades require switch downtime
  6. 6. Backup current configuration using 'configupload' command
  7. 7. Download the firmware from Broadcom/NetApp support portal
  8. 8. Run 'firmwaredownload' command to apply the update
