Overview

CVE-2023-30586 is a high-severity vulnerability. It was published on July 1, 2023 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

A privilege escalation vulnerability exists in Node.js 20 that allowed loading arbitrary OpenSSL engines when the experimental permission model is enabled, which can bypass and/or disable the permission model. The attack complexity is high. However, the crypto.setEngine() API can be used to bypass the permission model when called with a compatible OpenSSL engine. The OpenSSL engine can, for example, disable the permission model in the host process by manipulating the process's stack memory to locate the permission model Permission::enabled_ in the host process's heap memory. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
