Since September 27, Citrix has released three security bulletins for NetScaler ADC and Gateway; two of them address actively exploited vulnerabilities. Since then, anyone running an appliance has been asking themselves the same question every morning: Has anything happened to us?

Our solution is a shell script that runs on the appliance, doesn't change anything, and tells you what to do in just a few seconds. It was developed by Jens Miltenberger based on his practical experience with NetScaler environments. Available on GitHub starting today, under the Apache 2.0 license.
