"The version of nodejs18 / nodejs installed on the remote CBL Mariner 2.0 host is prior to tested version. It is,
therefore, affected by a vulnerability as referenced in the CVE-2024-22025 advisory.

  - A vulnerability in Node.js has been identified, allowing for a Denial of Service (DoS) attack through
    resource exhaustion when using the fetch() function to retrieve content from an untrusted URL. The
    vulnerability stems from the fact that the fetch() function in Node.js always decodes Brotli, making it
    possible for an attacker to cause resource exhaustion when fetching content from an untrusted URL. An
    attacker controlling the URL passed into fetch() can exploit this vulnerability to exhaust memory,
    potentially leading to process termination, depending on the system configuration. (CVE-2024-22025)

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