Every check ยท Headers

End-of-life software

headers/end-of-life

What it checks

The versions in the Server and X-Powered-By headers and the generator tag: PHP, Apache, nginx, IIS, OpenSSL and Drupal.

Why it matters

Software past its end of life gets no fixes, so every flaw found in it since stays open. Versions a long-term Linux distribution still patches are left alone.

How to fix it

  1. Upgrade to a supported version, or move to a host that keeps it up to date.
  2. Then turn the version numbers off, so they aren't announced.
