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

1. Open every .conf file (e.g., ssl.conf) included in $DOMAIN_HOME/config/fmwconfig/components/OHS//httpd.conf with an editor that requires an SSL-enabled "" directive. 2. Search for the "SSLVerifyClient" directive at the OHS server, virtual host, and/or directory configuration scopes. 3. If this directive is omitted or set improperly, this is a finding.

Fix text

1. Open every .conf file (e.g., ssl.conf) included in $DOMAIN_HOME/config/fmwconfig/components/OHS//httpd.conf with an editor that requires an SSL-enabled "" directive. 2. Search for the "SSLVerifyClient" directive at the OHS server, virtual host, and/or directory configuration scope. 3. Set the "SSLVerifyClient" directive to "require", add the directive if it does not exist.

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.
