"The version of Apache Tomcat installed on the remote host is 8.5.x
prior to 8.5.16. It is, therefore, affected by multiple
vulnerabilities :

  - A flaw exists in the CORS filter because the HTTP Vary header was
    not properly added. This allows a remote attacker to conduct
    client-side and server-side cache poisoning attacks.
    (CVE-2017-7674)

  - A flaw exists in the HTTP/2 implementation that bypasses a number
    of security checks that prevented directory traversal attacks. A
    remote attacker can exploit this to bypass security constraints.
    (CVE-2017-7675)

Note that Nessus has not attempted to exploit this issue but has
instead relied only on the application's self-reported version number.");
