Philips Xper Buffer Overflow Vulnerability

Act NowICS-CERT ICSA-13-277-01Jul 7, 2013
Summary

Philips Xper Information Management systems contain a buffer overflow vulnerability in system components used for Physiomonitoring, Vascular Monitoring, and Flex Cardio product lines. All versions are affected. No vendor fix is available.

What this means
What could happen
An attacker who gains access to vulnerable Xper systems could execute arbitrary code, potentially disrupting critical patient monitoring and cardiology operations in a hospital environment.
Who's at risk
Hospital IT and biomedical teams managing Philips Xper critical care monitoring systems. This affects facilities using Xper Information Management for patient physiomonitoring, vascular monitoring, or cardiology (Flex Cardio) applications where patient data collection and display depend on these servers and workstations.
How it could be exploited
An attacker would need to reach the Xper system components over the network (or via local access) and provide malformed input that overflows a buffer in the application. This would allow the attacker to execute arbitrary code on the affected monitoring or cardiology system.
Prerequisites
  • Network access to Xper Information Management system components
  • Ability to send malformed input to a vulnerable application interface

Remediation & Mitigation
0/4
Do now
0/3
HARDENINGImplement network segmentation to limit access to Xper systems from clinical and administrative networks; restrict only authorized monitoring and cardiology workstations
HARDENINGDisable remote access to Xper systems if not clinically required; use jump hosts or VPN with multi-factor authentication for any remote access
WORKAROUNDContact Philips to inquire about available mitigations, patches, or end-of-life timelines for affected systems
Schedule — requires maintenance window
0/1

Patching may require device reboot — plan for process interruption

HARDENINGMonitor Xper system activity logs for abnormal process execution or unexpected network connections
