Life2000 Ventilation System: Insufficient Logging

CVE-2024-48967 is a critical-severity insufficient logging vulnerability in Life2000 Ventilation System from Baxter, with a CVSS 3.1 base score of 10.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Life2000 Ventilation System versions: 06.08.00.00 and prior. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.63% chance of exploitation within 30 days, higher than 51% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update life2000_ventilator_firmware to 6.08.00.00 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

The ventilator and the Service PC lack sufficient audit logging capabilities to allow for detection of malicious activity and subsequent forensic examination. An attacker with access to the ventilator and/or the Service PC could, without detection, make unauthorized changes to ventilator settings that result in unauthorized disclosure of information and/or have unintended impacts on device performance.

The underlying weakness: Insufficient Logging

When a security-critical event occurs, the product either does not record the event or omits important details about the event when logging it.

How developers prevent this class of flaw

  • Use a centralized logging mechanism that supports multiple levels of detail.
  • Ensure that all security-related successes and failures can be logged. When storing data in the cloud (e.g., AWS S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to enable and capture detailed logging information.
  • Be sure to set the level of logging appropriately in a production environment. Sufficient data should be logged to enable system administrators to detect attacks, diagnose errors, and recover from attacks. At the same time, logging too much data (CWE-779) can cause the same problems, including unexpected costs when using a cloud environment.
