cyberstrikeus 6.3 Ensure scheme is set accurately (Automated)
Profile Applicability
• Level 1
Description
The scheme attribute is used to indicate to callers of request.getScheme() which scheme is in use by the Connector. Ensure the scheme attribute is set to http for Connectors operating over HTTP. Ensure the scheme attribute is set to https for Connectors operating over HTTPS.
Rationale
Maintaining parity between the scheme in use by the Connector and advertised by request.getScheme() will ensure applications built on Tomcat have an accurate depiction of the context and security guarantees provided to them.
Audit Procedure
Review the server.xml to ensure the Connector's scheme attribute is set to http for Connectors operating over HTTP. Also ensure the Connector's scheme attribute is set to https for Connectors operating over HTTPS.
Remediation
In server.xml, set the Connector's scheme attribute to http for Connectors operating over HTTP. Set the Connector's scheme attribute to https for Connectors operating over HTTPS.
<Connector
…
scheme="https"
…
/>
Default Value
The scheme attribute is set to http.
