Sicherheitsforscher haben kritische Schwachstellen in mehreren Tunneling-Protokollen gefunden, die weltweit 4,2 Millionen Systeme betreffen. Zu den betroffenen Protokollen geh\u00f6ren IP6IP6, GRE6, 4in6 und 6in4, die zur sicheren Daten\u00fcbertragung zwischen Netzwerken genutzt werden.<\/p>\n

Diese Protokolle versagen jedoch in der Identit\u00e4tspr\u00fcfung und Verschl\u00fcsselung, was Angreifern erm\u00f6glicht, die Systeme als Einweg-Proxies zu nutzen oder Denial-of-Service-Angriffe (DoS) zu starten. Au\u00dferdem k\u00f6nnen private Netzwerke von Organisationen potenziell gef\u00e4hrdet werden. Empfohlene Schutzma\u00dfnahmen sind IPsec, WireGuard sowie Paketfilterung und Deep Packet Inspection.<\/p>\n
