CVE-2018-19010 in Infinity Delta
Summary
by MITRE
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.

This vulnerability affects multiple medical device models including Drager Infinity Delta, Delta XL, Kappa, and Infinity Explorer C700 across all versions. The flaw resides in the network protocol handling mechanism where the devices fail to properly validate incoming network packets. When a malformed packet is received, the affected monitors experience unexpected system behavior leading to automatic reboot cycles. This represents a critical security weakness that directly impacts patient safety and medical device reliability in healthcare environments.
The technical implementation of this vulnerability demonstrates poor input validation practices within the network stack of these medical devices. The devices lack proper packet sanitization and error handling mechanisms that would normally prevent malformed data from causing system instability. According to CWE-20, this vulnerability falls under improper input validation, where the system fails to properly validate or sanitize input received from external sources. The absence of robust network packet filtering and validation creates an attack surface that can be exploited through network-based malicious activity.
The operational impact of this vulnerability extends beyond simple service disruption to potentially life-threatening situations in clinical environments. Repeated network packet injection can cause continuous reboot cycles that force devices into default configurations, effectively removing all network connectivity and patient monitoring capabilities. This disruption directly violates the availability requirements established by healthcare security standards and can compromise patient care delivery. The ATT&CK framework categorizes this as a denial of service attack using network protocols, where the adversary leverages device-specific vulnerabilities to create sustained disruption of critical medical services.
Security implications of this vulnerability are particularly severe in healthcare settings where continuous patient monitoring is essential. The repeated reboot cycles can result in loss of critical patient data, interruption of life-support systems, and potential harm to patients who depend on these devices for their care. Healthcare organizations must consider the broader implications of device availability and reliability when addressing this vulnerability. The remediation approach should include network segmentation, proper firewall rules to filter malicious packets, and firmware updates from the vendor to address the underlying protocol handling flaws. Additionally, monitoring systems should be implemented to detect and alert on unusual reboot patterns that may indicate exploitation attempts.
