Editorial Analysis
NetScaler appliances sit at the network edge of thousands of European enterprises; actively exploited RCE zero-days there can be the entry point for ransomware or espionage before any internal controls engage.
Immediately apply Citrix security updates or, if patching is delayed, shut down affected NetScaler instances and activate alternative access controls.
Two actively exploited zero-day vulnerabilities in Citrix NetScaler require emergency patching or shutdown to prevent potential network-wide compromise.
