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 Brocade Fabric OS versions before 9.2.1c2 could allow an administrator-level user to execute the bind command, to escalate privileges and bypass security controls allowing the execution of arbitrary commands.

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

This is a privilege escalation vulnerability in Brocade Fabric OS where an authenticated administrator-level user can abuse the bind command to bypass existing security controls and execute arbitrary commands on the system. The vulnerability allows a user with admin privileges to gain unauthorized elevated access beyond their intended authorization level.

MitigationUpgrade Brocade Fabric OS to version 9.2.1c2 or later to patch this vulnerability. Apply the update during a planned maintenance window after backing up the current configuration.

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. Determine the Fabric OS version
    Execute the 'version' or 'firmwareShow' command on the Fabric OS CLI to retrieve the installed firmware version
    Affected if The version number is less than 9.2.1c2, or greater than or equal to 9.2.2 but less than 9.2.2b
  2. Verify admin user access to the bind command
    Log in as an authenticated administrator and attempt to access the 'bind' command usage or help by typing 'bind' or 'help bind' in the Fabric OS CLI
    Affected if The bind command is accessible to admin-level users and returns command syntax or usage information
  3. Confirm authentication context
    Verify that the environment uses local Fabric OS authentication (not external AAA like RADIUS or TACACS+) by checking the 'aaaconfig --show' or 'licenseshow' output
    Affected if Local authentication is in use and the bind command is available to authenticated admin users

You are affected if your Fabric OS version falls within the range below 9.2.1c2 or between 9.2.2 and 9.2.2b, and admin users have access to the bind command.

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

Upgrade Brocade Fabric OS to version 9.2.1c2 or later to patch this vulnerability. Apply the update during a planned maintenance window after backing up the current configuration.

Recommended fix High confidence

Upgrade to Fabric OS 9.2.1c2 or later (for versions < 9.2.1c2); or upgrade to 9.2.2b or later (for versions >= 9.2.2)

  1. 1. Identify the current Fabric OS version using the 'version' or 'firmwareShow' command
  2. 2. If running a version < 9.2.1c2, plan upgrade to version 9.2.1c2 or later
  3. 3. If running version >= 9.2.2 but < 9.2.2b, plan upgrade to version 9.2.2b or later
  4. 4. Review upgrade prerequisites and compatibility in Broadcom support documentation before proceeding
  5. 5. Perform the firmware upgrade following standard Brocade Fabric OS upgrade procedures
  6. 6. After upgrade, verify the new version is running using 'version' command
  7. 7. Confirm the vulnerability is resolved by ensuring the bind command no longer allows privilege escalation
