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 16.1.x versions prior to 16.1.2.2, 15.1.x versions prior to 15.1.5.1, 14.1.x versions prior to 14.1.4.6, 13.1.x versions prior to 13.1.5, and all versions of 12.1.x 11.6.x, a DOM-based cross-site scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP AFM, CGNAT, and PEM Configuration utility that allows an attacker to execute JavaScript in the context of the currently logged-in user. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

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 DOM-based cross-site scripting (XSS) vulnerability in F5 BIG-IP AFM, CGNAT, and PEM Configuration utility allows attackers to execute malicious JavaScript in the context of currently logged-in users through an undisclosed page. The vulnerability stems from improper handling of user-supplied input in the DOM.

MitigationApply the vendor-supplied patches (16.1.2.2+, 15.1.5.1+, 14.1.4.6+, 13.1.5+) to the BIG-IP system. For end-of-life versions (12.1.x, 11.6.x), restrict administrative access to trusted networks or implement additional web application firewall protections.

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 BIG-IP version
    Log into the BIG-IP Configuration utility and navigate to System > Software Management > ISO Image, or run 'tmsh show sys version' via command line to retrieve the exact software version.
    Affected if The installed version falls within any of these ranges: 11.6.1-11.6.5, 12.1.0-12.1.6, 13.1.0-13.1.4, 14.1.0-14.1.4.5, 15.1.0-15.1.5.0, or 16.1.0-16.1.2.1.
  2. Check if AFM module is provisioned
    Run 'tmsh list sys provision module' or navigate to System > Software Management > Provisioning in the web interface to see which modules are provisioned.
    Affected if The Advanced Firewall Manager (AFM) module is provisioned on the system.
  3. Check if CGNAT module is provisioned
    Run 'tmsh list sys provision module' or check System > Software Management > Provisioning to see if Carrier Grade NAT is provisioned.
    Affected if The Carrier Grade NAT (CGNAT) module is provisioned on the system.
  4. Check if PEM module is provisioned
    Run 'tmsh list sys provision module' or check System > Software Management > Provisioning to see if Policy Enforcement Manager is provisioned.
    Affected if The Policy Enforcement Manager (PEM) module is provisioned on the system.
  5. Confirm Configuration utility access
    Verify that the BIG-IP Configuration utility (web-based management interface) is accessible. This is typically on port 443 or 8443.
    Affected if The Configuration utility is accessible and the affected modules (AFM, CGNAT, or PEM) are provisioned on a vulnerable version.

A system is affected if it runs a vulnerable BIG-IP version (11.6.1-11.6.5, 12.1.0-12.1.6, 13.1.0-13.1.4, 14.1.0-14.1.4.5, 15.1.0-15.1.5.0, or 16.1.0-16.1.2.1) AND has AFM, CGNAT, or PEM modules provisioned, with the Configuration utility accessible.

dbcve · scoped
Upgrade available Upgrade to 13.1.5 / 14.1.4.6 / 15.1.5.1 or later
Fixed in 13.1.514.1.4.615.1.5.1
Interim mitigation

Apply the vendor-supplied patches (16.1.2.2+, 15.1.5.1+, 14.1.4.6+, 13.1.5+) to the BIG-IP system. For end-of-life versions (12.1.x, 11.6.x), restrict administrative access to trusted networks or implement additional web application firewall protections.

Recommended fix High confidence

Upgrade to the earliest fixed version in your current major branch: 14.1.4.6 for 14.1.x, 13.1.5 for 13.1.x, 15.1.5.1 for 15.1.x, or 16.1.2.2 for 16.1.x. Versions 11.6.x and 12.1.x have no fix available as they are End of Technical Support.

  1. 1. Identify the current BIG-IP version by navigating to System > Software Management > ISO Image or checking the version displayed on the login page
  2. 2. Determine which major version line (11.6.x, 12.1.x, 13.1.x, 14.1.x, 15.1.x, or 16.1.x) is currently installed
  3. 3. For 14.1.x versions: upgrade to version 14.1.4.6 or later
  4. 4. For 13.1.x versions: upgrade to version 13.1.5 or later
  5. 5. For 15.1.x versions: upgrade to version 15.1.5.1 or later
  6. 6. For 16.1.x versions: upgrade to version 16.1.2.2 or later
  7. 7. Note: 11.6.x and 12.1.x have no fix available; these versions have reached End of Technical Support (EoTS) and require migration to a supported version
  8. 8. After upgrade, verify the fix by logging into the Configuration utility and confirming the undisclosed page no longer executes arbitrary JavaScript
Caveat Upgrading across major versions (e.g., 12.1 to 14.1) may require configuration and compatibility review; consult F5 upgrade guides. Version 11.6.x and 12.1.x have no patch available and require migration to a supported version.
