Vulnerability

Philips lists Capsule Neuron under Windows PEAP denial of service CVE-2023-21701

MedDevice Cyber Staff · Mar 29 · 2 min read · Via Philips product security advisories, 2023 archive

Philips listed Capsule Neuron on March 29, 2023, as related to CVE-2023-21701, a vulnerability in the Protected Extensible Authentication Protocol (PEAP) used in wireless networks and point-to-point connections. Successful exploitation could allow a remote attacker to cause a denial of service condition.

Capsule Neuron collects data from bedside devices, so a crash interrupts the flow of that data downstream. Check how each Neuron authenticates to the network before deciding whether PEAP is even in its path.

The flaw is in the OS inside the controller, or a system past end of service still in the field. As the maker, own the embedded OS and server lifecycle as a safety obligation, design controllers to update in the field, and make every fault degrade to a defined safe state.

Own the OS lifecycle. Patch the OS and server components on a schedule with a tested delivery path.
Design for field update. And for planned replacement, so an unpatchable unit has a path off the network.
Degrade to safe. A fault drives a defined safe state, never an unexpected stop on a life-sustaining device.
