Vulnerability

Baxter PrisMax 2.1 carries three Ripple20 flaws through its modified Treck stack

MedDevice Cyber Staff · Jul 30 · 2 min read · Via Baxter PrisMax Ripple20 bulletin

Baxter published a bulletin on July 30, 2020, under ICS advisory ICSA-20-168-01. PrisMax software version 2.1, when connected to an EMR/PDMS via Ethernet, uses GHnet v2, a modified Treck TCP/IP stack, and is affected by 3 of the 19 Ripple20 vulnerabilities: CVE-2020-11907, CVE-2020-11911 and CVE-2020-11914.

Baxter states the impact is limited to network connectivity. Limited still means charting gaps, so check how each unit behaves when its EMR link drops.

For ProvidersOperators, hospitals, and clinical engineering

The three Ripple20 flaws reach PrisMax 2.1 only through its Ethernet connection to an EMR/PDMS, and Baxter limits the impact to connectivity. Restrict that link to the EMR interface host and follow Baxter's bulletin for software updates.

Identify connected units. List PrisMax 2.1 units with an Ethernet link to the EMR/PDMS.
Restrict the link. Allow traffic to those units only from the EMR interface host.
Test link loss. Confirm documentation workflows hold when a unit loses its EMR connection.

For Device ManufacturersAm I affected, and how to fix the class

Am I affected?

This class applies to devices with the signals and properties below. Check them against your product to gauge exposure. The named product rows list what the sources state about the affected product.

Fix the class in your product

The advisory is not for a bug you wrote; it is in a component you embed. As the maker, pin dependencies to fixed versions, generate an SBOM on every build including transitive components, and gate the pipeline on known-vulnerable components so an advisory maps to your products automatically.

Pin and inventory. Exact versions, and a CycloneDX or SPDX SBOM as a build artifact including transitive deps.
Gate on advisories. A CI scan fails a release carrying a component with a known advisory.
Own the field patch path. Know how you deliver a dependency or platform patch to fielded devices before you need it.
