Produktbeschreibung

Citrix Application Delivery Controller (ADC) ist eine Lösung zur Anwendungsbereitstellung und Lastverteilung. Citrix NetScaler ist eine integrierte Lösung für die Beschleunigung, das Traffic Management und die Sicherheit von Web-Applikationen. Citrix Access Gateway ist ein universell einsetzbares SSL-VPN. Advanced Access Control (AAC) ermöglichen es Administratoren, Zugriffsregeln für das Access Gateway festzulegen.

Angriff

Ein Angreifer aus einem angrenzenden Netzwerk kann mehrere Schwachstellen in Citrix Systems ADC und Citrix Systems NetScaler ausnutzen, um Sicherheitsvorkehrungen zu umgehen, oder um einen Denial-of-Service auszulösen.
