Philips Brilliance Computed Tomography (CT) System (Update A)
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. Also, attackers may gain access to unauthorized resources from the underlying Windows operating system.CVE-2018-8853 has been assigned to this vulnerability. A CVSS v3 base score of 6.1 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:L). Vulnerabilities within the Brilliance CT kiosk environment 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.CVE-2018-8861 has been assigned to this vulnerability. A CVSS v3 base score of 6.1 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:L). The software contains fixed credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. An attacker could compromise these credentials and gain access to the system.CVE-2018-8857 has been assigned to this vulnerability. A CVSS v3 base score of 8.4 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
