CVE-2024-14036: Dräger Core 1.0.5 Denial of Service via Malformed SDC Message

Dräger Core 1.0.5 and Dräger M540 Converter Service 1.0.9 contain a denial of service vulnerability that allows network-adjacent attackers to trigger high CPU load by sending specially crafted, unencrypted SDC messages during the discovery process. Attackers with access to the hospital network can send malformed SDC packets to exhaust CPU resources in the affected process, causing further SDC messages to no longer be processed.

Security readout for executives and security teams

Plain-English summary

CVE-2024-14036 can let an attacker on a hospital network disrupt Dräger communication components by causing excessive CPU load. The reported impact is denial of service: affected processes may stop processing further SDC messages. No public source in the bundle states active exploitation.

Executive priority

Treat as a high-priority healthcare availability issue if affected Dräger components are deployed. Prioritize network containment and vendor-guided remediation because disruption could affect device communication workflows.

Technical view

Dräger Core 1.0.5 and Dräger M540 Converter Service 1.0.9 are affected. Malformed, unencrypted SDC messages during discovery can trigger resource exhaustion in the affected process. The CVSS 4.0 score is 8.7 with high availability impact and no stated confidentiality or integrity impact.

Likely exposure

Exposure is most likely in healthcare environments running the affected Dräger versions where hospital network access can reach SDC discovery traffic. Internet exposure is not stated in the provided sources.

Exploitation context

The attacker needs network access to the hospital environment and can send crafted SDC discovery traffic. Sources do not indicate authentication, user interaction, or special privileges are required. No KEV listing or cited source confirms exploitation in the wild.

Researcher notes

The source bundle identifies CWE-400 resource exhaustion and CVSS 4.0 AV:N/AC:L/PR:N/UI:N with VA:H only. Remediation specifics are not included in the provided text, so validation should be tied to Dräger’s advisory rather than assumed fixes.

Mitigation direction

  • Check Dräger PSA-24-110-1 for official remediation guidance.
  • Identify and prioritize affected Dräger Core and M540 Converter Service deployments.
  • Restrict SDC discovery traffic to trusted medical-device network segments.
  • Limit access from guest, user, and unmanaged device networks.
  • Monitor affected systems for abnormal CPU load or SDC processing failures.

Validation and detection

  • Inventory Dräger Core and M540 Converter Service versions in clinical networks.
  • Confirm whether Core 1.0.5 or M540 Converter Service 1.0.9 is present.
  • Review network paths that can reach SDC discovery services.
  • Check logs and monitoring for high CPU events in affected processes.
  • Verify remediation status against the Dräger advisory.
