ErrorReportValve showServerInfo must be set to false.
An XCCDF Rule
Description
The Error Report Valve is a simple error handler for HTTP status codes that will generate and return HTML error pages. It can also be configured to return pre-defined static HTML pages for specific status codes and/or exception types. Disabling showServerInfo will only return the HTTP status code and remove all CSS from the default non-error related HTTP responses.
