bioMérieux finds Ripple20 flaws in networked HP printers shipped with its systems

MedDevice Cyber Staff · Oct 14 · 2 min read · Via bioMérieux security advisories

bioMérieux updated its Ripple20 advisory on October 14, 2020. The company found that HP SL-M4020ND printers delivered with some of its commercial systems in the past are affected by the Ripple20 vulnerabilities in the Treck TCP/IP stack when used through network connectivity instead of USB.

Ripple20 is the set of flaws the JSOF research group disclosed in Treck's network library, some confirmed as critical by CERTs because they may allow remote code execution or expose sensitive information. bioMérieux told customers to check whether they use networked HP SL-M4020ND printers with their bioMérieux systems and to update the printer firmware following HP's advisory.

The fix lives in a peripheral, outside the analyzer's own patch cycle. Printers that ship in the box belong in the same asset inventory as the instrument they serve.

For ProvidersOperators, hospitals, and clinical engineering

HP SL-M4020ND printers delivered with some bioMérieux systems are affected by Ripple20 when networked. Update the printer firmware per HP's advisory, or connect the printer over USB, which bioMérieux says is not affected.

Find the printers. Inventory HP SL-M4020ND printers attached to bioMérieux systems and note which use network connectivity.
Update firmware. Apply the HP firmware update named in HP's Ripple20 advisory to each networked unit.
Prefer USB. Where network printing is not needed, connect the printer to the bioMérieux system over USB.

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.
