"The version of Tomcat installed on the remote host is prior to 8.5.16. It is, therefore, affected by multiple
vulnerabilities as referenced in the fixed_in_apache_tomcat_8.5.16_security-8 advisory.

  - The HTTP/2 implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M21 and 8.5.0 to 8.5.15 bypassed a number of
    security checks that prevented directory traversal attacks. It was therefore possible to bypass security
    constraints using a specially crafted URL. (CVE-2017-7675)

  - The CORS Filter in Apache Tomcat 9.0.0.M1 to 9.0.0.M21, 8.5.0 to 8.5.15, 8.0.0.RC1 to 8.0.44 and 7.0.41 to
    7.0.78 did not add an HTTP Vary header indicating that the response varies depending on Origin. This
    permitted client and server side cache poisoning in some circumstances. (CVE-2017-7674)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
