CVE-2025-30406Gladinet CentreStack — hardcoded key forges the view state

CentreStack up to 16.1.10296.56315 ships a fixed framework key, so anyone who knows it signs a crafted view state that the portal then deserializes into running code. Exploited in the wild from March 2025.

YOUR NEXT MOVE

Upgrade CentreStack to 16.4.10315.56368 or later and rotate the framework key now; assume an exposed portal was already reached.
