BD tests Microsoft fix for CryptoAPI spoofing flaw CVE-2020-0601

MedDevice Cyber Staff · Jan 31 · 3 min read · Via BD bulletin: BD Product Security Bulletin for Third-Party CryptoAPI Vulnerability

BD published a third-party bulletin on January 31, 2020 for CVE-2020-0601, a spoofing flaw in Windows CryptoAPI ECC certificate validation that Microsoft disclosed. BD lists products that use affected Windows versions, reports no exploitation, and is testing Microsoft's patch.

Certificate validation is what lets a device trust a signed update, a TLS server or a signed executable. A flaw that lets a forged ECC certificate pass breaks all three at once.

Devices that verify code signatures through the OS inherit the OS's mistakes. Patch the validation layer first.

For ProvidersOperators, hospitals, and clinical engineering

BD was testing Microsoft's patch for CVE-2020-0601 as of January 31, 2020. Apply it on BD systems running affected Windows versions once BD validates it. Until then, do not rely on OS certificate checks alone for code from outside the hospital.

Apply the validated patch. Install Microsoft's CVE-2020-0601 update on BD systems after BD clears it.
Control software sources. Load updates onto BD systems only from BD-supplied media or channels.
Pin update certificates. Manufacturers should pin the expected signing certificate rather than trust any chain the OS accepts.

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.
