CVE-2019-25717: Dräger Patient Monitor Info Disclosure

CVE-2019-25717 Overview

CVE-2019-25717 is an information disclosure vulnerability affecting Dräger Infinity Delta, Delta XL, and Kappa patient monitors. Unauthenticated attackers on an adjacent network can retrieve log files directly from affected devices over the network. The exposed logs reveal device internals, physical location information, and wired network configuration details. The flaw is categorized under [CWE-538], which covers insertion of sensitive information into externally accessible files or directories. Exposed data enables attackers to map clinical environments, fingerprint device firmware, and prepare follow-on attacks against hospital networks. Patient monitors operate in sensitive clinical settings, so disclosure of network topology and device metadata raises operational risk for healthcare providers.

Critical Impact

Unauthenticated network access to log files containing device internals, location data, and wired network configuration of affected Dräger patient monitors.

Technical Details for CVE-2019-25717

Vulnerability Analysis

The affected Dräger Infinity Delta, Delta XL, and Kappa patient monitors expose log files through a network-accessible interface that does not require authentication. An attacker positioned on an adjacent network segment can request and retrieve these log files directly. The logs contain operational and diagnostic data generated by the monitor during normal use. This includes device internals such as firmware behavior indicators, physical location identifiers configured by clinical staff, and wired network configuration parameters. The CWE-538 classification identifies the underlying weakness as sensitive information placed in a file accessible to unauthorized parties. The vulnerability does not affect integrity or availability of the patient monitor itself, but it leaks reconnaissance data useful to attackers targeting hospital infrastructure.

Root Cause

The root cause is the absence of access control on log file retrieval. The patient monitors store diagnostic and configuration data in log files and serve them over a network service without authenticating the requester. Sensitive operational data is co-located with general diagnostic information, so any unauthenticated retrieval exposes the full contents.

Attack Vector

Exploitation requires network adjacency to the targeted patient monitor. The attacker connects to the network service hosting log file access and issues a retrieval request. No credentials, user interaction, or elevated privileges are required. The attacker then parses the returned logs for device internals, location metadata, and wired network configuration details. This data supports lateral movement planning and targeted attacks against clinical network segments. Refer to the VulnCheck Advisory for Patient Monitors for technical specifics on the exposed interface.

Detection Methods for CVE-2019-25717

Indicators of Compromise

• Unauthenticated network connections to Dräger Infinity Delta, Delta XL, or Kappa monitors originating from non-clinical hosts
• Outbound transfers of log file content from patient monitor IP addresses to unexpected destinations
• Repeated probing of patient monitor network services from a single source on the local segment

Detection Strategies

• Inventory all Dräger Infinity Delta, Delta XL, and Kappa monitors and confirm their network segment isolation
• Monitor network traffic to and from biomedical device VLANs for connections that do not match approved clinical workflows
• Deploy intrusion detection signatures that flag log file retrieval requests against patient monitor IP ranges

Monitoring Recommendations

• Capture full packet metadata at the boundary of biomedical device VLANs for forensic review
• Alert on any host outside the biomedical management subnet that initiates a session with a patient monitor
• Review patient monitor access logs, where supported, and correlate with authorized clinical engineering activity

How to Mitigate CVE-2019-25717

Immediate Actions Required

• Isolate affected Dräger Infinity Delta, Delta XL, and Kappa monitors on dedicated VLANs with strict access control lists
• Restrict network reachability of patient monitors to authorized clinical engineering workstations only
• Contact Dräger support to confirm patch availability and obtain vendor remediation guidance

Patch Information

Consult the Dräger Security Resources portal for vendor advisories, firmware updates, and remediation instructions specific to Infinity Delta, Delta XL, and Kappa patient monitors. Apply vendor-supplied updates through approved clinical engineering change control processes.

Workarounds

• Segment patient monitor networks from general hospital networks and guest Wi-Fi using firewall rules
• Block inbound connections to patient monitor log file services at the network layer where clinical operations permit
• Enforce 802.1X or MAC-based network access control on switch ports connected to biomedical devices

# Example ACL restricting access to a patient monitor VLAN
# Permit only the clinical engineering management subnet
access-list 110 permit ip 10.20.30.0 0.0.0.255 10.50.60.0 0.0.0.255
access-list 110 deny   ip any 10.50.60.0 0.0.0.255 log
