Vulnerability

Philips lists the HeartStart Intrepid monitor/defibrillator under the Ripple20 Treck TCP/IP flaws

MedDevice Cyber Staff · Jun 18 · 2 min read · Via Philips security advisory

Philips published a Ripple20 advisory on June 18, 2020. JSOF researchers disclosed 19 zero-day vulnerabilities in the Treck TCP/IP stack that could lead to remote code execution or exposure of sensitive information.

Philips lists the HeartStart Intrepid Monitor/Defibrillator (867172) as affected, a model not sold in the US. A TCP/IP stack is buried deep in firmware and shared across vendors, which is why Ripple20 reached so many device makers at once.

A defibrillator with a network stack has a network attack surface. Know which embedded stacks ship in your products before the next Ripple20 lands.

For ProvidersOperators, hospitals, and clinical engineering

Philips lists the HeartStart Intrepid (867172) as affected by Ripple20. Get the firmware fix from Philips service and keep the device off untrusted networks until it is applied. Review SBOMs for other Treck stack users.

Identify Intrepid units. Find HeartStart Intrepid (867172) devices in the fleet.
Obtain the firmware fix. Ask Philips service for the update that addresses the Treck stack flaws.
Limit network exposure. Keep the monitor/defibrillator on an isolated segment until patched.
Check the SBOM. Search component inventories for the Treck TCP/IP stack in other products.

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.
