Successful exploitation of this vulnerability could allow an attacker to access credentials to the hospitalβs clinical information systems (EMR).
The following versions of IntelliBridge Enterprise (IBE), an interface, are affected:
The IntelliBridge Enterprise (IBE) provides HL7 interface interoperability between Philips products and a hospitalβs clinical information system or electronic medical records by providing a single integration point to the enterprise. The IBE software and connection licenses serve as the main messaging service that implements communications, mapping, message delivery, data transformation, and routing of data to and from the Philips products to external systems. IntelliBridge Enterprise has no clinical user interface, nor does it interpret, inspect, or provide additional analytical functionality for medical device data.
Workflows affected:
IntelliBridge Enterprise system integration with,
Unencrypted user credentials received in the IntelliBridge Enterprise (IBE) are logged within the transaction logs, which are secured behind the login based administrative web portal.
The unencrypted user credentials sent from the affected products listed above, for the purpose of handshake or authentication with the
Enterprise Systems, are logged as the payload in IntelliBridge Enterprise (IBE) within the transaction logs. An attacker with administrative privileges could exploit this vulnerability to read plain text credentials from log files.
CVE-2020-12023 has been assigned to this vulnerability. A CVSS v3 base score of 2.0 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N).
Customer Indiana University Health reported this vulnerability to Philips.
Philips plans a new release (IBE B.13) by the end of Q4 2020 that remediates the security risk by not logging the plain text user credentials in the log file.
As an interim mitigation to this vulnerability, Philips recommends the following:
