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

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)
