"The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by
multiple vulnerabilities as referenced in the K000137090 advisory.

  - Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Denial of Service with large
    HTTP headers: By using a combination of many requests with maximum sized headers (almost 80 KB per
    connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to
    abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other
    proxy layer. (CVE-2018-12121)

  - Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Slowloris HTTP Denial of
    Service: An attacker can cause a Denial of Service (DoS) by sending headers very slowly keeping HTTP or
    HTTPS connections and associated resources alive for a long period of time. (CVE-2018-12122)

  - Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Hostname spoofing in URL parser
    for javascript protocol: If a Node.js application is using url.parse() to determine the URL hostname, that
    hostname can be spoofed by using a mixed case javascript: (e.g. javAscript:) protocol (other protocols
    are not affected). If security decisions are made about the URL based on the hostname, they may be
    incorrect. (CVE-2018-12123)

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