"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2020:4272 advisory.

  - Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through
    log files. The CLI supports URLs like
    <protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>. The password value is not redacted
    and is printed to stdout and also to any generated log files. (CVE-2020-15095)

  - Prototype pollution vulnerability in dot-prop npm package versions before 4.2.1 and versions 5.x before
    5.1.1 allows an attacker to add arbitrary properties to JavaScript language constructs such as objects.
    (CVE-2020-8116)

  - Node.js < 12.18.4 and < 14.11 can be exploited to perform HTTP desync attacks and deliver malicious
    payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison
    cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the
    underlying system. The attack was possible due to a bug in processing of carrier-return symbols in the
    HTTP header names. (CVE-2020-8201)

  - The implementation of realpath in libuv < 10.22.1, < 12.18.4, and < 14.9.0 used within Node.js 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.");
