CVE-2020-16212
N/A
Summary
In Patient Information Center iX (PICiX) Versions B.02, C.02, C.03, the product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource. The application on the surveillance station operates in kiosk mode, which is vulnerable to local breakouts that could allow an attacker with physical access to escape the restricted environment with limited privileges.

Weaknesses
- CWE-668: CWE-668 Exposure of Resource to Wrong Sphere
Workarounds
As a mitigation to these vulnerabilities, Philips recommends the following:
- The Philips patient monitoring network is required to be physically or logically isolated from the hospital local area network (LAN). Philips recommends using a firewall or routers that can implement access control lists restricting access in and out of the patient monitoring network for only necessary ports and IP addresses. Refer to the Philips Patient Monitoring System Security for Clinical Networks guide for additional information on InCenter https://incenter.medical.philips.com/) .
- By default, the simple certificate enrollment protocol (SCEP) service is not running. When needed, the service is configured to run based on the duration or the number of certificates to be assigned. One certificate is default, but if a certificate is not issued, the service will continue to run. Limit exposure by ensuring the SCEP service is not running unless it is actively being used to enroll new devices.
- When enrolling new devices using SCEP, enter a unique challenge password of 8-12 unpredictable and randomized digits.
- Implement physical security controls to prevent unauthorized login attempts on the PIC iX application. Servers should be kept in controlled locked data centers. Access to equipment at nurses’ stations should be controlled and monitored.
- Only grant remote access to PIC iX servers on a must-have basis.
- Grant login privileges to the bedside monitor and PIC iX application on a role-based, least-privilege basis, and only to trusted users.
