Ensure secure is set to true only for SSL-enabled Connectors

MittelStufe 1Automatisierttomcat

Beschreibung

The secure attribute is used to convey Connector security status to applications operating over the Connector. This is typically achieved by calling request.isSecure(). Ensure the secure attribute is only set to true for Connectors operating with the SSLEnabled attribute set to true. For every Connector: SSLEnabled="true" requires secure="true"; other connectors must have secure unset or "false". Reads $CATALINA_BASE (default /opt/tomcat) and $CATALINA_HOME (default: $CATALINA_BASE); set them for packaged installs (e.g. CATALINA_BASE=/var/lib/tomcat10, CATALINA_HOME=/usr/share/tomcat10). XML comments are ignored.

Erwartete Ausgabe: compliant

So wird behoben

Behebungsmethode: Anleitung oder Infrastruktur-Patch

Set secure="true" on TLS connectors and secure="false" (or none) on the others in server.xml. Restart Tomcat afterwards.
