3) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU79335

Risk: Medium

CVSSv4.0: 6.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-32559

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to usage of deprecated API process.binding(). A remote attacker 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.

Mitigation

Install updates from vendor's website.
