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
When an SSL profile is configured on a Virtual Server, undisclosed traffic can cause an increase in CPU or SSL accelerator resource utilization.   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

This is a denial-of-service vulnerability in F5 BIG-IP where certain undisclosed traffic patterns sent to a Virtual Server with an SSL profile configured can cause excessive CPU or SSL accelerator resource utilization, potentially degrading or disrupting services.

MitigationApply the vendor-supplied patch or upgrade to a F5 BIG-IP version that addresses CVE-2023-24594, and verify SSL profile functionality post-update.

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 system version
    Run command 'tmsh show sys version' or view the version in the web UI under System > Platform
    Affected if The installed version is exactly 14.1.5, 15.1.4.1, or 16.1.2
  2. Identify Virtual Servers configured
    Run command 'tmsh list ltm virtual one-line' to list all virtual servers, or view them in the web UI under Local Traffic > Virtual Servers
    Affected if Any Virtual Servers exist on the system
  3. Verify SSL profile attachment
    Examine the virtual server output for 'profile clientssl' or 'profile serverssl' entries, or run 'tmsh list ltm virtual <name> profiles' for each virtual server
    Affected if Any Virtual Server has an SSL client or server profile assigned

The environment is affected if running exactly version 14.1.5, 15.1.4.1, or 16.1.2 AND has at least one Virtual Server configured with an SSL profile.
