"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2020:0579 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)

  - Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It is possible for
    packages to create symlinks to files outside of thenode_modules folder through the bin field upon
    installation. A properly constructed entry in the package.json bin field would allow a package publisher
    to create a symlink pointing to arbitrary files on a user's system when the package is installed. This
    behavior is still possible through install scripts. This vulnerability bypasses a user using the --ignore-
    scripts install option. (CVE-2019-16775)

  - Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It fails to prevent
    access to folders outside of the intended node_modules folder through the bin field. A properly
    constructed entry in the package.json bin field would allow a package publisher to modify and/or gain
    access to arbitrary files on a user's system when the package is installed. This behavior is still
    possible through install scripts. This vulnerability bypasses a user using the --ignore-scripts install
    option. (CVE-2019-16776)

  - Versions of the npm CLI prior to 6.13.4 are vulnerable to an Arbitrary File Overwrite. It fails to prevent
    existing globally-installed binaries to be overwritten by other package installations. For example, if a
    package was installed globally and created a serve binary, any subsequent installs of packages that also
    create a serve binary would overwrite the previous serve binary. This behavior is still allowed in local
    installations and also through install scripts. This vulnerability bypasses a user using the --ignore-
    scripts install option. (CVE-2019-16777)

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