The host is installed with Node.js 12.x before 12.22.9, 14.x before 14.18.3, 16.x before 16.13.2, 17.x before 17.3.1 and is prone to an improper certificate validation vulnerability. A flaw is present in the application which fails to handle the URI SAN type when checking a certificate against a hostname. Successful exploitation allows an attacker to bypass name-constrained intermediates, and also Node.js could not match the URI correctly when a protocol allows URI SANs.
