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.
