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
An origin validation vulnerability exists in BIG-IP APM browser network access VPN client for Windows, macOS and Linux which may allow an attacker to bypass F5 endpoint inspection. 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 · moderate confidence

An origin validation vulnerability in BIG-IP APM's browser-based network access VPN client for Windows, macOS, and Linux allows attackers to bypass F5 endpoint inspection controls by improperly validating the origin of requests or connections.

MitigationApply F5's available security patches or upgrade to a supported version of BIG-IP APM to address the origin validation bypass in the VPN client components.

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 APM server version
    Run 'tmsh show /sys version' or access the web UI under System > Software Management > ISO IMAGES to identify the installed BIG-IP APM version
    Affected if The version falls within 15.1.0 - 15.1.10.2, 16.1.0 - 16.1.4.1, or exactly 17.1.0
  2. Check APM Client version
    On Windows, check the installed version of 'F5 Big IP Access Policy Manager Client' in Programs and Features or via the client software itself if installed
    Affected if The client version is 7.2.3 through 7.2.4.3
  3. Verify browser-based network access VPN is in use
    Check APM access policy configurations via TMSH 'list /apm profile access' or the web UI under Access Policy > Access Profiles to see if browser-based network access resources are assigned
    Affected if Browser-based network access VPN resources are configured and active
  4. Confirm endpoint inspection controls are enabled
    Review the access policy in the web UI under Access Policy > Visual Policy Editor or via TMSH to verify endpoint inspection modules such as endpoint checks, antivirus, or device certificates are configured
    Affected if Endpoint inspection controls are defined in the access policy for the VPN session

You are affected if you run a vulnerable BIG-IP APM version (15.1.x before 15.1.10.3, 16.1.x before 16.1.4.2, or 17.1.0) OR a vulnerable APM Client version (7.2.3 - 7.2.4.3) AND have browser-based network access VPN configured with endpoint inspection controls enabled.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Fixed in 7.2.4.415.1.10.316.1.4.2
Interim mitigation

Apply F5's available security patches or upgrade to a supported version of BIG-IP APM to address the origin validation bypass in the VPN client components.

Recommended fix High confidence

BIG-IP APM: 15.1.10.3, 16.1.4.2, or 17.1.1+ | APM Client: 7.2.4.4

  1. 1. Identify the current version of BIG-IP APM and BIG-IP APM Client in your environment
  2. 2. Download the fixed version from F5 downloads: upgrade to 15.1.10.3 (or 16.1.4.2, or 17.1.1+) for the BIG-IP APM system
  3. 3. Download and deploy BIG-IP APM Client version 7.2.4.4 or later for all affected endpoints (Windows, macOS, Linux)
  4. 4. Schedule a maintenance window for the upgrade following F5 upgrade procedures
  5. 5. Apply the upgrade to the BIG-IP APM system
  6. 6. Distribute the updated APM Client to all VPN users
  7. 7. Verify the origin validation fix is working by testing the endpoint inspection functionality
Caveat Review F5 upgrade documentation for any compatibility notes between your current and target version; ensure client-side requirements are met for 7.2.4.4
