The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-5532 advisory.

  • The use of Module._load() can bypass the policy mechanism and require modules outside of the policy.json definition for a given module. This vulnerability affects all users using the experimental policy mechanism in all active release lines: 16.x, 18.x and, 20.x. Please note that at the time this CVE was issued, the policy is an experimental feature of Node.js. (CVE-2023-32002)

  • The use of module.constructor.createRequire() can bypass the policy mechanism and require modules outside of the policy.json definition for a given module. This vulnerability affects all users using the experimental policy mechanism in all active release lines: 16.x, 18.x, and, 20.x. Please note that at the time this CVE was issued, the policy is an experimental feature of Node.js. (CVE-2023-32006)

  • A privilege escalation vulnerability exists in the experimental policy mechanism in all active release lines: 16.x, 18.x and, 20.x. The use of the deprecated API process.binding() can bypass the policy mechanism by requiring internal modules and eventually take advantage of process.binding('spawn_sync') run arbitrary code, outside of the limits defined in a policy.json file. Please note that at the time this CVE was issued, the policy is an experimental feature of Node.js. (CVE-2023-32559)

Note that Nessus has not tested for these issues but has instead relied only on the applicationโ€™s self-reported version number.
