CBL Mariner 2.0 Security Update: nodejs (CVE-2023-23918)

The version of 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-2023-23918 advisory.

  • A privilege escalation vulnerability exists in Node.js <19.6.1, <18.14.1, <16.19.1 and <14.21.3 that made it possible to bypass the experimental Permissions (https://nodejs.org/api/permissions.html) feature in Node.js and access non authorized modules by using process.mainModule.require(). This only affects users who had enabled the experimental permissions option with --experimental-policy. (CVE-2023-23918)

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