Summary
NetScaler ADC and NetScaler Gateway products are affected when configured as a Gateway (such as VPN, ICA Proxy, CVPN, or RDP Proxy virtual servers) or as an AAA virtual server, as well as when load balancing virtual servers or CR virtual servers handle IPv6 or HDX traffic. A successful attack could allow an attacker to run code remotely on the device or crash it, causing a denial of service.
