Der Fehler besteht aufgrund eines Logikfehlers, wenn verschiedene Protokolle behandelt werden, aber kompatible Zertifikate verwendet werden, wie z. B. Multi-Domain- oder Wildcard-Zertifikate. Ein entfernter anonymer Angreifer, der in der Lage ist, einen MitM-Angriff auf der TCP/IP-Schicht durchzuf\u00fchren, kann den Datenverkehr von einer Subdomain auf eine andere bzw. von einem Dienst auf einen anderen umleiten, was zu einer g\u00fcltigen TLS-Sitzung f\u00fchrt. Der Angreifer kann dies ausnutzen, um Sicherheitsma\u00dfnahmen zu umgehen und um andere unbekannte Auswirkungen hervorzurufen."
