"The version of Tomcat installed on the remote host is prior to 9.0.0.M21. It is, therefore, affected by a vulnerability
as referenced in the fixed_in_apache_tomcat_9.0.0.m21_security-9 advisory.

  - The error page mechanism of the Java Servlet Specification requires that, when an error occurs and an
    error page is configured for the error that occurred, the original request and response are forwarded to
    the error page. This means that the request is presented to the error page with the original HTTP method.
    If the error page is a static file, expected behaviour is to serve content of the file as if processing a
    GET request, regardless of the actual HTTP method. The Default Servlet in Apache Tomcat 9.0.0.M1 to
    9.0.0.M20, 8.5.0 to 8.5.14, 8.0.0.RC1 to 8.0.43 and 7.0.0 to 7.0.77 did not do this. Depending on the
    original request this could lead to unexpected and undesirable results for static error pages including,
    if the DefaultServlet is configured to permit writes, the replacement or removal of the custom error page.
    Notes for other user provided error pages: (1) Unless explicitly coded otherwise, JSPs ignore the HTTP
    method. JSPs used as error pages must must ensure that they handle any error dispatch as a GET request,
    regardless of the actual method. (2) By default, the response generated by a Servlet does depend on the
    HTTP method. Custom Servlets used as error pages must ensure that they handle any error dispatch as a GET
    request, regardless of the actual method. (CVE-2017-5664)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
