- Engineer — Plan: NetScaler Gateway and ADC are widely deployed edge appliances with a strong exploitation history; apply Citrix’s patches within your next maintenance window and verify no unpatched instances are internet-facing. No KEV listing or public PoC present to justify emergency patching, but Citrix’s urgency language warrants prioritizing this over routine patching cycles.
