Description Preview
A vulnerability in Philips IntelliVue patient monitoring systems allows attackers to cause a denial-of-service condition through improper input validation. When the affected devices receive certain malformed inputs, they fail to properly validate the data, which can trigger system restarts and potentially disrupt patient monitoring capabilities.
Overview
This vulnerability (CVE-2020-16216) affects multiple Philips IntelliVue patient monitoring systems, including models MX100, MX400-550, MX600, MX700, MX750, MX800, MX850, MP2-MP90, and IntelliVue X2 and X3 Versions N and prior. The issue stems from insufficient input validation, where the devices do not properly validate received data before processing it. When exploited, this vulnerability can cause the monitoring system to restart, resulting in a denial-of-service condition that could temporarily interrupt patient monitoring functions in healthcare environments. This vulnerability is particularly concerning in critical care settings where continuous patient monitoring is essential.
Remediation
Healthcare facilities using affected Philips IntelliVue patient monitors should:
- Contact Philips Healthcare to determine if patches or firmware updates are available for their specific device models
- Implement network segmentation to isolate medical devices from untrusted networks
- Restrict physical and network access to authorized personnel only
- Monitor systems for unusual behavior or unexpected restarts
- Develop and maintain contingency plans for monitoring patients in case of system failures
- Follow Philips' security advisories and implement recommended mitigations
- Consider implementing compensating controls such as additional monitoring systems in critical care areas
