Vulnerability

Philips MRI 1.5T and 3T software has access control and ownership flaws in versions 5.3 to 5.8.1

MedDevice Cyber Staff · Nov 9 · 2 min read · Via Philips security advisory

Philips issued an advisory on November 9, 2021 on its MRI 1.5T and MRI 3T systems, versions 5.3 through 5.8.1. The company identified three potential vulnerabilities: improper access control, incorrect ownership assignment for resources, and potential exposure of sensitive information to unauthorized actors.

On an MRI console, incorrect ownership means files or processes owned by the wrong account, which lets a lower-privileged user change what a higher-privileged one runs. Sensitive information on a scanner usually means patient studies.

Scanner consoles are shared logins in practice. The access control fix only works if the accounts on top of it are individual.

The login worked; the authorization did not follow through on every object the request names. As the maker, authorize every object reference on the server against the caller, return uniform responses so nothing can be enumerated, and strip internal detail from what the backend returns.

Authorize per object. Check on the server that the caller may see the specific record a request names, on every request.
Answer uniformly. Login and lookup respond identically for present and absent accounts.
Return generic errors. Log detail server-side; never leak internal state to the client.
