Vulnerability discussion

A certificate's certification path is the path from the end entity certificate to a trusted root certification authority (CA). Certification path validation is necessary for a relying party to make an informed decision regarding acceptance of an end entity certificate. Certification path validation includes checks such as certificate issuer trust, time validity and revocation status for each certificate in the certification path. Revocation status information for CA and subject certificates in a certification path is commonly provided via certificate revocation lists (CRLs) or online certificate status protocol (OCSP) responses.

Check content

Review the web server documentation and deployed configuration to determine whether the web server provides PKI functionality that validates certification paths in accordance with RFC 5280. If PKI is not being used, this is NA. If the web server is using PKI, but it does not perform this requirement, this is a finding.

Fix text

Configure the web server to validate certificates in accordance with RFC 5280.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
