CVE-2024-9832 Baxter CVE debrief

CVE-2024-9832 is a critical authentication vulnerability in the Baxter Life2000 Ventilation System, published by CISA on November 14, 2024. The device fails to implement rate limiting on failed login attempts for both the Clinician Password and Serial Number Clinician Password, enabling brute-force attacks that could grant unauthorized access to device settings. Successful exploitation could result in disruption of ventilator function or unauthorized information disclosure. The CVSS 3.1 score of 9.3 reflects severe impact across confidentiality, integrity, and availability with local attack vector but no privileges required. Baxter has not yet released a patch; the vendor plans a follow-up announcement in Q2 2025. Current mitigations rely entirely on physical security controls—users must maintain possession of devices and avoid leaving them unattended in unsecured areas. No exploitation has been reported to date.

Who should care

Healthcare delivery organizations, biomedical engineering teams, respiratory therapy departments, clinical engineering, hospital security operations, and medical device risk management personnel responsible for ventilator fleet security and patient safety.

Technical summary

The Baxter Life2000 Ventilation System (versions <=06.08.00.00) contains an authentication weakness where no limit exists on failed login attempts for clinician passwords. This absence of rate limiting enables offline or online brute-force attacks against the Clinician Password or Serial Number Clinician Password. Successful authentication bypass grants attackers the ability to modify ventilator settings, potentially causing device malfunction or exposing sensitive patient data. The vulnerability requires local physical access but no privileges, with scope change indicating impact beyond the vulnerable component.

Defensive priority

critical

Recommended defensive actions

  • Implement strict physical access controls for all Life2000 Ventilation System devices; never leave devices unattended in public or unsecured areas
  • Monitor for unauthorized physical access attempts to ventilator units in clinical and transport environments
  • Await Baxter's Q2 2025 security update and apply promptly upon release
  • Review and reinforce clinical workflows to ensure continuous physical custody of ventilators during patient transport or temporary storage
  • Consider network segmentation and access logging for any connected monitoring infrastructure supporting Life2000 devices
