CVE-2023-32559
Description
A vulnerability was found in NodeJS. This security issue occurs as 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') to run arbitrary code outside of the limits defined in a policy.json file.
Statement
When this CVE was reported, the policy.json file was still experimental in nature and not deployed and widely in environments,which is why at the time when this CVE was submitted,Redhat chose to classify this as moderare.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Red Hat CVSS v3 Score Explanation
The attack complexity is high because it required some knowledge and effort to exploit, primarily due to the use of a deprecated API, the experimental nature of the feature, and the need to bypass a policy mechanism. It wasn't a straightforward or easy attack but still posed a significant risk to specific Node.js versions. The attacker requires privileges that provide basic user capabilities that could normally affect only settings and files owned by a user.
