• EPSS: 1.3% probability of exploitation in the next 30 days

• Weakness: CWE-862

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.

Affected products

• Node.js: from 20.0.0 before 20.3.1 — fixed in 20.3.1

How to fix

Upgrade to a fixed version: Node.js 20.3.1. Check the vendor advisory for mitigations.
