CVE-2021-44531

Disclosure Date: February 24, 2022 •
CVE-2021-44531 CVSS v3 Base Score: 7.4
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

Accepting arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type, can result in bypassing name-constrained intermediates. Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 was accepting URI SAN types, which PKIs are often not defined to use. Additionally, when a protocol allows URI SANs, Node.js did not match the URI correctly.Versions of Node.js with the fix for this disable the URI SAN type when checking a certificate against a hostname. This behavior can be reverted through the —security-revert command-line option.
