Wildcard-Policy für URL-Adressen schützt Clientless SSL VPN

(PresseBox) (München, )
Das amerikanische Computer Emergency Readyness Team (US-CERT) meldete am 30.11.2009, dass einige Produkte für Clientless SSL VPN einen Sicherheitsmechanismus von Webbrowsern aushebeln. Angreifer können damit beispielsweise Authentifizierungsprozesse umgehen, sensible Daten stehlen oder andere Web-Attacken starten.

Der Sicherheitsmechanismus "Same Origin Policy" für Browser und Webanwendungen dient dazu, dass Objekte einer Website oder Webbasierenden Anwendung wie beispielsweise Cookies nicht von einer anderen Quelle ausgelesen werden können. JavaScript oder ActionSkript dürfen nur dann auf Objekte zugreifen, falls sie aus derselben Quelle stammen. Wenn für eine VPN-Verbindung vor den Domain-Namen der Name des VPN-Servers gesetzt ist, greift die Same Origin Policy nicht mehr, da nlvz Pknolbt obo mkagerbzm nuw tbofw Tzqvqd cxukasl, wbek kgbs fijcba kokhazsrmzctponc Mqvlnwl vlypxo.
