Vulnerabilities within the Philips Brilliance CT kiosk environment (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) could enable a limited-access kiosk user or an unauthorized attacker to break-out from the containment of the kiosk environment, attain elevated privileges from the underlying Windows OS, and access unauthorized resources from the operating system.

Weakness

The product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource.

Affected Software

Name Vendor Start Version End Version
Brilliance_firmware_64 Philips * 2.6.2 (including)

Extended Description

Resources such as files and directories may be inadvertently exposed through mechanisms such as insecure permissions, or when a program accidentally operates on the wrong object. For example, a program may intend that private files can only be provided to a specific user. This effectively defines a control sphere that is intended to prevent attackers from accessing these private files. If the file permissions are insecure, then parties other than the user will be able to access those files. A separate control sphere might effectively require that the user can only access the private files, but not any other files on the system. If the program does not ensure that the user is only requesting private files, then the user might be able to access other files on the system. In either case, the end result is that a resource has been exposed to the wrong party.
