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
In BIG-IP 15.0.0-15.1.0.4, 14.1.0-14.1.2.7, 13.1.0-13.1.3.3, 12.1.0-12.1.5.2, and 11.6.1-11.6.5.2 and BIG-IQ 5.2.0-7.1.0, unauthenticated attackers can cause disruption of service via undisclosed methods.

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

Unauthenticated remote attackers can cause disruption of service on affected F5 BIG-IP and BIG-IQ devices. The vulnerability is rated HIGH (CVSS 7.5) and affects multiple versions across the 11.x, 12.x, 13.x, 14.x, and 15.x product lines, as well as BIG-IQ versions 5.2.0-7.1.0. The specific attack vector and technical details are undisclosed in the advisory.

MitigationApply the vendor-supplied patches/updates to upgrade to a fixed version outside the affected version ranges. For BIG-IP: 15.1.0.5+, 14.1.2.8+, 13.1.3.4+, 12.1.5.3+, 11.6.5.3+. For BIG-IQ: 7.1.0.1+ or later.

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 installed BIG-IP version
    Run `tmsh show /sys version` or check the web UI under System > Software Management > ISO Image. Alternatively, run `bigpipe version` from the command line.
    Affected if The version falls within 11.6.1-11.6.5, 12.1.0-12.1.5, 13.1.0-13.1.3.3, 14.1.0-14.1.2.7, or 15.1.0-15.1.0.4.
  2. Verify if any affected BIG-IP modules are provisioned
    Run `tmsh list /sys provision` to list all provisioned modules. Check the 'level' column - any module with a level other than 'none' is provisioned.
    Affected if Any of these modules are provisioned: APM, AFM, Analytics, AAM, ASM, DNS, Edge Gateway, or Fraud Protection Service, AND the version is in the affected range.
  3. Check BIG-IQ version if applicable
    Log into the BIG-IQ web interface and navigate to the System > Software Management page, or run `tmsh show /sys version` from the CLI.
    Affected if The BIG-IQ version is between 5.2.0 and 7.1.0 inclusive.
  4. Confirm the specific module version (optional)
    For each provisioned affected module, run `tmsh list /sys software` or check the installed hotfixes via `tmsh show /sys hotfix`.
    Affected if The module version matches the affected BIG-IP version ranges listed in step 1.

You are affected if your BIG-IP version falls within the vulnerable ranges AND any of the eight affected modules (APM, AFM, Analytics, AAM, ASM, DNS, Edge Gateway, Fraud Protection Service) are provisioned, or if your BIG-IQ version is between 5.2.0 and 7.1.0.
