This updated advisory is a follow-up to the original advisory titled ICSA-20-170-03 Baxter Phoenix Hemodialysis Delivery System that was published June 18, 2020, on the ICS webpage on us-cert.gov.
Successful exploitation of this vulnerability could allow an attacker with unauthorized network access to view sensitive data.
The following versions of the Phoenix Hemodialysis Delivery System are affected:
The Phoenix Hemodialysis device does not support data-in-transit encryption (e.g., TLS/SSL) when transmitting treatment and prescription data on the network between the Phoenix system and the Exalis dialysis data management tool. An attacker with access to the network could observe sensitive treatment and prescription data sent between the Phoenix system and the Exalis tool.
CVE-2020-12048 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
Baxter reported this vulnerability to CISA.
Baxter recommends users apply the following implementation guidance:
Users should also identify, analyze, evaluate, and control all risks associated with integration of medical devices in an enterprise network. Subsequent changes to the enterprise network could introduce new risks and require new analysis.
