"The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the
FEDORA-2023-6b866fbe84 advisory.

  - The use of __proto__ in process.mainModule.__proto__.require() can bypass the policy mechanism and require
    modules outside of the policy.json definition. This vulnerability affects all users using the experimental
    policy mechanism in all active release lines: v16, v18 and, v20. Please note that at the time this CVE was
    issued, the policy is an experimental feature of Node.js (CVE-2023-30581)

  - A vulnerability has been identified in the Node.js (.msi version) installation process, specifically
    affecting Windows users who install Node.js using the .msi installer. This vulnerability emerges during
    the repair operation, where the msiexec.exe process, running under the NT AUTHORITY\SYSTEM context,
    attempts to read the %USERPROFILE% environment variable from the current user's registry. The issue arises
    when the path referenced by the %USERPROFILE% environment variable does not exist. In such cases, the
    msiexec.exe process attempts to create the specified path in an unsafe manner, potentially leading to
    the creation of arbitrary folders in arbitrary locations. The severity of this vulnerability is heightened
    by the fact that the %USERPROFILE% environment variable in the Windows registry can be modified by
    standard (or non-privileged) users. Consequently, unprivileged actors, including malicious entities or
    trojans, can manipulate the environment variable key to deceive the privileged msiexec.exe process. This
    manipulation can result in the creation of folders in unintended and potentially malicious locations. It
    is important to note that this vulnerability is specific to Windows users who install Node.js using the
    .msi installer. Users who opt for other installation methods are not affected by this particular issue.
    (CVE-2023-30585)

  - When an invalid public key is used to create an x509 certificate using the crypto.X509Certificate() API a
    non-expect termination occurs making it susceptible to DoS attacks when the attacker could force
    interruptions of application processing, as the process terminates when accessing public key info of
    provided certificates from user code. The current context of the users will be gone, and that will cause a
    DoS scenario. This vulnerability affects all active Node.js versions v16, v18, and, v20. (CVE-2023-30588)

  - The llhttp parser in the http module in Node v20.2.0 does not strictly use the CRLF sequence to delimit
    HTTP requests. This can lead to HTTP Request Smuggling (HRS). The CR character (without LF) is sufficient
    to delimit HTTP header fields in the llhttp parser. According to RFC7230 section 3, only the CRLF sequence
    should delimit each header-field. This impacts all Node.js active versions: v16, v18, and, v20
    (CVE-2023-30589)

  - The generateKeys() API function returned from crypto.createDiffieHellman() only generates missing (or
    outdated) keys, that is, it only generates a private key if none has been set yet, but the function is
    also needed to compute the corresponding public key after calling setPrivateKey(). However, the
    documentation says this API call: Generates private and public Diffie-Hellman key values. The documented
    behavior is very different from the actual behavior, and this difference could easily lead to security
    issues in applications that use these APIs as the DiffieHellman may be used as the basis for application-
    level security, implications are consequently broad. (CVE-2023-30590)

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