Vulnerability

Philips Engage Software 6.2.1 and prior let authenticated users view business contact data

MedDevice Cyber Staff · Jan 6 · 2 min read · Via CISA ICSMA-22-006-01

CISA published advisory ICSMA-22-006-01 on January 6, 2022, covering Philips Engage Software versions 6.2.1 and prior. Parnassia and S-Unit are credited.

CVE-2021-23173 (CWE-284) is improper access control that may let an authenticated user gain unauthorized access to sensitive data. CISA's risk evaluation narrows that to improper read-only viewing of business contact information. The CVSS v3 score is 2.6, with high attack complexity, low privileges and user interaction all required.

Engage is a hosted application, so the fix shipped server side. Philips released and deployed Version 6.2.2 in September 2021, months before the advisory went out, and users do not need to take any action. Hosted delivery means the vendor patches once for everyone, and advisories like this one arrive as a record of work already done.

For ProvidersOperators, hospitals, and clinical engineering

No action is required from users: Philips deployed Engage Software Version 6.2.2 to its hosted service in September 2021, fixing CVE-2021-23173. Confirm with Philips service that your tenant runs 6.2.2 or later and review which accounts can reach business contact records.

Confirm the hosted version. Check with Philips service support that your Engage instance runs Version 6.2.2 or later.
Review user access. Remove Engage accounts that no longer need access, since the flaw required an authenticated user.
Test object-level authorization. For your own hosted products, verify every record request checks the caller's rights to that specific record.

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.
