CVE-2020-12048Network attack vector

Treatment data disclosure via unencrypted Exalis traffic

Published Jun 29, 2020 · Updated Aug 4, 2024

Cleartext transmission in Baxter PHOENIX X36 software 3.36 and 3.40 allows remote attackers to read treatment and prescription data. The device sends this sensitive data to the Exalis dialysis data management tool without TLS or other data-in-transit encryption. Exploitation requires access to the Phoenix-Exalis network path and exposes confidentiality without altering treatment data or interrupting dialysis.
