Philips Brilliance CT devices operate user functions from within a contained kiosk in a Microsoft Windows operating system. Windows boots by default with elevated Windows privileges, enabling a kiosk application, user, or an attacker to potentially attain unauthorized elevated privileges in Brilliance 64 version 2.6.2 and prior, Brilliance iCT versions 4.1.6 and prior, Brillance iCT SP versions 3.2.4 and prior, and Brilliance CT Big Bore 2.3.5 and prior. Also, attackers may gain access to unauthorized resources from the underlying Windows operating system.
