SSL certificate of a subdomain with a wrong host name


The certificate for {Subdomain.Name} belongs to a different hostname. Certificates can authenticate only specific hostnames, stated either in the Common Name (CN) or as an Subject Alternative Name (SAN). Certificates can not guarantee ownership of a subdomain which is not listed in one of those. This means a user could not distinguish access to the correct website and a fake one and opens users of this website to the risk of an MITM attack
