## Affected

- Dräger Infinity Acute Care System: through VG4.1.1; through VG4.0.3
- Dräger Standalone Infinity M540 patient monitor: through VG4.1.1

## Description

Dräger Infinity Acute Care System and Standalone Infinity M540 patient monitors running software versions VG4.1.1, VG4.0.3, and lower contain network message handling vulnerabilities that allow network-adjacent attackers to spoof or tamper with data and cause denial-of-service conditions. Attackers with access to an enabled Infinity network port or physical proximity to a wireless access point can modify device settings such as alarm states or alarm limits, and overwhelm the system with incoming data causing the device to reboot and lose network functionality.
