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
On BIG-IP 14.1.0-14.1.0.5, 14.0.0-14.0.0.5, 13.0.0-13.1.1.4, 12.1.0-12.1.4.1, and 11.5.1-11.6.4, an undisclosed iControl REST worker is vulnerable to command injection by an administrator or resource administrator user. This attack is only exploitable on multi-bladed systems.

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

An authenticated command injection vulnerability exists in the iControl REST API on F5 BIG-IP devices. An administrator or resource administrator user can inject commands through an undisclosed REST worker, leading to arbitrary command execution on the underlying system. The vulnerability is specific to multi-bladed BIG-IP systems.

MitigationUpgrade BIG-IP to a version beyond 14.1.0.5/14.0.0.5/13.1.1.4/12.1.4.1/11.6.4 as specified in F5 advisory K21905555. Limit administrative access to trusted personnel and audit admin account usage as an interim control.

CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

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 if the BIG-IP system is multi-bladed
    Run 'tmsh show sys hardware' or check the output of 'tmsh show sys cluster' to see if multiple blades are present. On single-blade systems or VIPRION chassis, check the 'Chassis Information' section in the web UI under Dashboard or use 'tmsh show sys hardware' and look for multiple blade entries.
    Affected if The system is single-bladed (not affected) - the vulnerability only affects multi-bladed BIG-IP systems
  2. Determine the installed BIG-IP version
    Run 'tmsh show sys version' or access the web UI and check the version displayed on the login page or under System > Software Management > ISO Image. Compare the version number against the affected ranges: 11.5.1-11.6.4, 12.1.0-12.1.4, 13.0.0-13.1.1.4, or 14.0.0-14.1.0.5.
    Affected if The installed version falls within any of the affected version ranges listed
  3. Confirm iControl REST API is exposed
    Verify the iControl REST API service is running by checking the output of 'tmsh show restjavad' or by attempting a local HTTPS request to https://localhost/mgmt/shared/authz/login. Also verify port 443 (or custom management port) is open for REST access.
    Affected if The iControl REST API is accessible and running on the system
  4. Verify administrative user access exists
    Check for existing administrator or resource administrator user accounts using 'tmsh list auth user' or by reviewing user partitions and roles in the web UI under User Management > User List.
    Affected if Any administrator or resource administrator accounts exist on the system (authenticated access is required for exploitation)

You are affected if you have a multi-bladed BIG-IP system running a version within 11.5.1-11.6.4, 12.1.0-12.1.4, 13.0.0-13.1.1.4, or 14.0.0-14.1.0.5, with iControl REST API exposed and any administrator accounts present.

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.
