Predictable exact value from previous values vulnerability in Citrix NetScaler ADC and Citrix NetScaler Gateway. This issue affects ADC: before 14.1-73.37, before 13.1-64.23, before 14.1-73.37 FIPS, and before 13.1.37.279 FIPS and NDcPP; Gateway: before 14.1-73.37 and before 13.1-64.23.

What it is to other things

affects	citrix/netscaler_application_delivery_controller NVD
affects	citrix/netscaler_gateway NVD
made_by	citrix NVD

In words only, so not counted until a person confirms one:

made_by	`citrix_netscaler` NVD says “Citrix NetScaler”
affects	`citrix_netscaler/adc` NVD says “Citrix NetScaler · ADC”
