 - Denial of Service in NetScaler ADC and NetScaler Gateway when configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server. (CVE-2023-4967)

Please refer to advisory CTX579459 for more information.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
