This updated advisory is a follow-up to the original advisory titled ICSMA-20-196-01 Capsule Technologies SmartLinx Neuron 2 that was published July 14, 2020, on the ICS webpage on us-cert.cisa.gov.
Successful exploitation of this vulnerability could provide an attacker with full control of a trusted device on a hospital’s internal network.
The following versions of Capsule Technologies SmartLinx Neuron 2, a medical device platform, are affected:
--------- Begin Update A Part 1 of 2 ---------
--------- End Update A Part 1 of 2 ---------
A restricted environment escape vulnerability exists in the “kiosk mode” function of Capsule Technologies SmartLinx Neuron 2 medical information collection devices running
Version 6.9.1. A specific series of keyboard inputs can allow an escape from the restricted environment, resulting in full administrator access to the underlying operating system. An attacker can connect to the device via USB port with a keyboard or other HID device to trigger this vulnerability.
CVE-2019-5024 has been assigned to this vulnerability. A CVSS v3 base score of 7.6 has been calculated; the CVSS vector string is (AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
Patrick DeSantis of Cisco Talos reported this vulnerability to Capsule Technologies.
Capsule Technologies recommends the following mitigations:
--------- Begin Update A Part 2 of 2 ---------
--------- End Update A Part 2 of 2 ---------
* Connect the Neuron 2 to the Capsule SmartLinx application server.
