Vulnerability

Boston Scientific rates BootHole risk low across devices that use Secure Boot

MedDevice Cyber Staff · Sep 16 · 2 min read · Via Boston Scientific BootHole statement

Boston Scientific published a statement, Revision 1, on September 16, 2020, on the BootHole vulnerability, CVE-2020-10713. The company assessed its devices that use Linux or Windows Secure Boot and rated the risk as low.

BootHole is a buffer overflow in how the GRUB2 bootloader parses its configuration file, letting code run before the operating system loads and undercutting Secure Boot. An attacker needs elevated access first, which drives a low rating.

Patches can be applied at the next scheduled software update, and Boston Scientific says no urgent patching is required. That is a reasonable call for a pre-boot flaw, provided the scheduled update actually ships.

For ProvidersOperators, hospitals, and clinical engineering

Boston Scientific rates BootHole as low risk and will ship fixes with the next scheduled software update. Take that update when offered and keep administrative access to affected devices limited in the meantime.

Take the scheduled update. Install the next Boston Scientific software update that carries the BootHole fix.
Limit administrative access. Restrict who can reach the boot configuration on Secure Boot devices.
Confirm revocation handling. Ask Boston Scientific how bootloader revocation lists are updated on affected devices.

For Device ManufacturersFix the class in the product

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.
