"The version of Node.js installed on the remote host is prior to 10.22.1 or 12.18.4 or 14.11.0. It is, therefore,
affected by multiple vulnerabilities as referenced in the september-2020-security-releases advisory.

  - Affected Node.js versions converted carriage returns in HTTP request headers to a hyphen before parsing.
    This can lead to HTTP Request Smuggling as it is a non-standard interpretation of the header.
    (CVE-2020-8201)

  - Node.js is vulnerable to HTTP denial of service (DOS) attacks based on delayed requests submission which
    can make the server unable to accept new connections. The fix a new http.Server option called requestTimeout
    with a default value of 0 which means it is disabled by default. This should be set when Node.js is used
    as an edge server. (CVE-2020-8251)

  - libuv's realpath implementation incorrectly determined the buffer size which can result in a buffer overflow
    if the resolved path is longer than 256 bytes. (CVE-2020-8252)

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