MEDIUM 5.3 Microsoft

CVE-2021-44533

Node.js < 12.22.9 < 14.18.3 < 16.13.2 and < 17.3.1 did not handle multi-value Relative Distinguished Names correctly. Attackers could craft certificate subjects containing a single-value Relative Distinguished Name that would be interpreted as a multi-value Relative Distinguished Name for example in order to inject a Common Name that would allow bypassing the certificate subject verification.Affected versions of Node.js that do not accept multi-value Relative Distinguished Names and are thus not vulnerable to such attacks themselves. However third-party code that uses node's ambiguous presentation of certificate subjects may be vulnerable.
