"According to its banner, the version of Apache running on the remote
host is 2.4.x prior to 2.4.38. It is, therefore, affected by multiple
vulnerabilities:

  - A denial of service (DoS) vulnerability exists in HTTP/2 steam
    handling. An unauthenticated, remote attacker can exploit this
    issue, via sending request bodies in a slow loris way to plain
    resources, to occupy a server thread. (CVE-2018-17189)

  - A vulnerability exists in mod_sesion_cookie, as it does not
    properly check the expiry time of cookies. (CVE-2018-17199) 

  - A denial of service (DoS) vulnerability exists in mod_ssl when
    used with OpenSSL 1.1.1 due to an interaction in changes to
    handling of renegotiation attempts. An unauthenticated, remote
    attacker can exploit this issue to cause mod_ssl to stop
    responding. (CVE-2019-0190)

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