It's time for another round Citrix Patch Diffing! Earlier this month Citrix released a security bulletin which mentioned "unauthenticated buffer-related vulnerabilities" and two CVEs. These issues affected Citrix NetScaler ADC and NetScaler Gateway.

While most of the attention for vulnerabilities within Citrix has been on their NetScaler VPN product, we noticed that there were several other products offered by Citrix that require an on-premise deployment of a web application, that is sometimes internet facing. This piqued our interest and led us to investigate the security of these self-hosted applications.
