This updated advisory is a follow-up to the original advisory titled ICSMA-19-318-01 Philips IntelliBridge EC40/80 that was published November 14, 2019, on the ICS webpage on us-cert.gov.
Successful exploitation of this vulnerability may allow an attacker unauthorized access to the IntelliBridge EC40/80 hub and may allow access to execute software, modify system configuration, or view/update files, including unidentifiable patient data.
The following versions of IntelliBridge are affected:
The IntelliBridge EC40/80 is intended to transfer medical device data from one format to another according to preset specifications. It performs data transfer without controlling or altering the function or parameters of any connected medical devices. The EC40/80 is not intended for use in connection with active patient monitoring. If data is not received from the hub a notification is generated on the PIC iX Central Station and customers are advised to refer to the source medical device.
The SSH server running on the affected products is configured to allow weak ciphers. This could enable an unauthorized attacker with access to the network to capture and replay the session and gain unauthorized access to the EC40/80 hub.
CVE-2019-18241 has been assigned to this vulnerability. A CVSS v3 base score of 6.3 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).
The Medical Technology Solutions team of NewYork-Presbyterian Hospital reported this vulnerability to Philips.
Philips plans a new release to remediate this vulnerability by the end of Q3 2020.
