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 all versions of 16.1.x, 15.1.x, 14.1.x, 13.1.x, 12.1.x, and 11.6.x of F5 BIG-IP APM, and F5 BIG-IP Guided Configuration (GC) all versions prior to 9.0, a reflected cross-site scripting (XSS) vulnerability exists in an undisclosed page of F5 BIG-IP Guided Configuration 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 reflected cross-site scripting (XSS) vulnerability exists in F5 BIG-IP Guided Configuration (all versions prior to 9.0) and BIG-IP APM (versions 11.6.x through 16.1.x). The flaw allows injection of malicious JavaScript through an undisclosed page, executing in the context of the victim's browser session when they interact with the crafted link.

MitigationUpgrade F5 BIG-IP Guided Configuration to version 9.0 or later, and apply the appropriate BIG-IP APM hotfix for your major version line (11.6.x, 12.1.x, 13.1.x, 14.1.x, 15.1.x, or 16.1.x) to address this vulnerability.

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 BIG-IP Guided Configuration is installed
    Check the Guided Configuration version by accessing the F5 management interface or using tmsh command 'show /sys software' to list installed software components
    Affected if Guided Configuration version is present and less than 9.0
  2. Identify if BIG-IP APM is installed
    Verify APM module is loaded by running 'tmsh show /apm' or checking the modules section in the F5 web management console under System > Software Management > Bare Metal Installer
    Affected if APM module is installed and the version falls within 11.6.x through 16.1.x (specifically 13.1.0-13.1.5, 14.1.0-14.1.4, or 15.1.0-15.1.2)
  3. Confirm the specific BIG-IP APM version
    Run 'tmsh show /sys version' or check the F5 management console Dashboard for the exact APM version number
    Affected if Version matches any of these: 13.1.0, 13.1.1, 13.1.3, 13.1.4, 13.1.5, 14.1.0, 14.1.2, 14.1.3, 14.1.4, 15.1.0, 15.1.1, or 15.1.2
  4. Check if the vulnerable Guided Configuration component is accessible
    Verify Guided Configuration is accessible by attempting to reach the configuration interface through the F5 management URL or by checking if the /gc/ endpoint responds
    Affected if Guided Configuration is exposed and accessible without updated to version 9.0 or later

Your environment is affected if BIG-IP Guided Configuration is present at any version below 9.0, OR if BIG-IP APM is installed at versions 13.1.0-15.1.2 (or falls within the 11.6.x-16.1.x range) and the undisclosed vulnerable page is accessible to users.
