"The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-6380-1 advisory.

  - Improper Certificate Validation in Node.js 10, 12, and 13 causes the process to abort when sending a
    crafted X.509 certificate (CVE-2019-15604)

  - HTTP request smuggling in Node.js 10, 12, and 13 causes malicious payload delivery when transfer-encoding
    is malformed (CVE-2019-15605)

  - Including trailing white space in HTTP header values in Nodejs 10, 12, and 13 causes bypass of
    authorization based on header value comparisons (CVE-2019-15606)

  - napi_get_value_string_*() allows various kinds of memory corruption in node < 10.21.0, 12.18.0, and <
    14.4.0. (CVE-2020-8174)

  - Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 are vulnerable to a use-after-free bug in its
    TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls
    node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method
    does not return an error, this object is passed back to the caller as part of a StreamWriteResult
    structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other
    exploits. (CVE-2020-8265)

  - Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 allow two copies of a header field in an HTTP
    request (for example, two Transfer-Encoding header fields). In this case, Node.js identifies the first
    header field and ignores the second. This can lead to HTTP Request Smuggling. (CVE-2020-8287)

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