CVE-2019-25716 in Infinity Delta
Summary
by MITRE • 06/02/2026
Drager Infinity Delta, Infinity Delta, all versions, Delta XL, all versions, Kappa, all version, and Infinity Explorer C700, all versions. A malformed network packet may cause the monitor to reboot. By repeatedly sending the malformed network packet, an attacker may be able to disrupt patient monitoring by causing the monitor to repeatedly reboot until it falls back to default configuration and loses network connectivity.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The Dräger Infinity Delta, Delta XL, and Kappa patient monitors represent critical medical devices in healthcare environments where continuous patient monitoring is essential for patient safety and clinical operations. These devices are designed to provide real-time physiological data monitoring for patients in intensive care units and other critical care settings. The vulnerability under examination affects the network communication protocols implemented within these medical devices, creating a significant risk to patient care continuity and healthcare delivery. The affected models are part of Dräger's advanced patient monitoring portfolio that relies heavily on network connectivity for data transmission and remote access capabilities.
This vulnerability constitutes a remote denial-of-service condition that exploits weaknesses in the network packet processing mechanisms of these medical devices. Attackers can remotely transmit malformed network packets to the affected monitors, which triggers a system-level reboot operation without requiring physical access or authentication credentials. The technical flaw exists in the device's network stack implementation where insufficient input validation and error handling routines fail to properly process malformed packets. This weakness allows attackers to leverage the network interface to repeatedly send crafted packets that cause the device to continuously restart its operating system. The vulnerability is particularly concerning because it can be exploited over the network without any prior authentication or privileged access, making it accessible to any attacker with network connectivity to the device.
The operational impact of this vulnerability extends beyond simple device disruption to potentially compromise patient safety and clinical workflows. When the affected monitors repeatedly reboot, they lose their current network configuration and fall back to default settings, resulting in complete loss of network connectivity. This disruption can occur during critical patient monitoring periods, potentially leading to gaps in patient data collection and transmission to central monitoring systems. Healthcare facilities may experience cascading effects as patient data becomes unavailable in electronic health records, monitoring stations, and clinical information systems. The repeated reboot cycles can also cause data loss from the device's internal memory, potentially resulting in incomplete patient records and compromised clinical decision-making processes. The vulnerability affects the availability and reliability of critical healthcare infrastructure, which can lead to regulatory compliance issues and potential liability concerns for healthcare organizations.
Mitigation strategies for this vulnerability should prioritize immediate network segmentation and access controls to limit exposure to unauthorized network traffic. Healthcare organizations should implement network access control lists that restrict direct network access to these devices from untrusted networks and enforce strict firewall rules that filter malformed network packets. The devices should be configured to operate in isolated network segments with minimal necessary network services enabled. Regular network monitoring should be implemented to detect unusual traffic patterns that may indicate exploitation attempts. Device firmware updates from Dräger should be applied immediately upon availability, as these updates typically include patched network stack implementations that address the input validation issues. Network administrators should also consider implementing intrusion detection systems that can identify and alert on malformed packet patterns targeting medical devices. Organizations should develop incident response procedures specifically for medical device security incidents, including protocols for device restoration and data recovery following exploitation attempts. This vulnerability highlights the importance of maintaining robust security practices for medical devices and aligns with CWE-129, which addresses validation of input boundaries, and ATT&CK technique T1499.004 for network denial of service attacks targeting medical devices.
