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 versions 16.1.x before 16.1.3.1, 15.1.x before 15.1.6.1, 14.1.x before 14.1.5.1, and 13.1.x before 13.1.5.1, When the Advanced WAF / ASM module is provisioned, an authenticated remote code execution vulnerability exists in the BIG-IP iControl REST interface.

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

An authenticated remote code execution vulnerability exists in the BIG-IP iControl REST interface when the Advanced WAF/ASM module is provisioned. An attacker with valid authentication credentials can execute arbitrary code on the affected system. This affects versions 16.1.x before 16.1.3.1, 15.1.x before 15.1.6.1, 14.1.x before 14.1.5.1, and 13.1.x before 13.1.5.1.

MitigationUpgrade BIG-IP to the fixed versions (16.1.3.1, 15.1.6.1, 14.1.5.1, or 13.1.5.1). As a compensating control, restrict access to the iControl REST interface to trusted administrative IPs only.

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. Check BIG-IP version
    Run 'tmsh show sys version' or query the iControl REST endpoint GET /mgmt/tm/sys/version and compare the version string against the affected ranges: 13.1.0 to <13.1.5.1, 14.1.0 to <14.1.5.1, 15.1.0 to <15.1.6.1, or 16.1.0 to <16.1.3.1
    Affected if The installed version falls within any of the listed vulnerable version ranges
  2. Verify ASM module provisioning
    Run 'tmsh list sys provision asm' or query GET /mgmt/tm/sys/provision/asm to check if the Application Security Manager module is provisioned
    Affected if The output shows 'provision-level' set to 'dedicated' or 'nominal' (not 'none')
  3. Verify Advanced WAF module provisioning
    Run 'tmsh list sys provision av' or query GET /mgmt/tm/sys/provision/av to check if the Advanced WAF module is provisioned
    Affected if The output shows 'provision-level' set to 'dedicated' or 'nominal' (not 'none')

The environment is affected if the BIG-IP version is within the vulnerable ranges AND either ASM or Advanced WAF is provisioned on the system.

Upgrade available Upgrade to 13.1.5.1 / 14.1.5.1 / 15.1.6.1 or later
Fixed in 13.1.5.114.1.5.115.1.6.1
Interim mitigation

Upgrade BIG-IP to the fixed versions (16.1.3.1, 15.1.6.1, 14.1.5.1, or 13.1.5.1). As a compensating control, restrict access to the iControl REST interface to trusted administrative IPs only.

Recommended fix High confidence

Upgrade to version 13.1.5.1, 14.1.5.1, 15.1.6.1, or 16.1.3.1 (or later) depending on your current branch

  1. 1. Identify the current BIG-IP version by running 'tmsh show sys version' or checking the web management console
  2. 2. Determine which version branch your current installation is on (13.1.x, 14.1.x, 15.1.x, or 16.1.x)
  3. 3. Download the appropriate fixed version from the F5 Networks support portal (support.f5.com) - requires valid F5 account and service agreement
  4. 4. Create a full system backup including UCS archive: run 'tmsh save sys ucs /var/local/ucs/backup_name.ucs'
  5. 5. Schedule a maintenance window as upgrades require brief service interruption
  6. 6. Follow F5 BIG-IP upgrade guide: upload the ISO/image via web UI or tmsh, then install using 'tmsh install sys software' command
  7. 7. After upgrade, verify version matches fixed release: 'tmsh show sys version'
  8. 8. Confirm Advanced WAF/ASM module is functioning correctly and test critical functionality
Caveat F5 BIG-IP upgrades may require downtime; ensure backup and test in staging environment first; some configuration adjustments may be needed after major version upgrades
