The affected BD medical devices utilize a method of software application implementation called βkiosk mode.β This kiosk mode is vulnerable to local breakouts, which could allow an attacker with physical access to bypass kiosk mode and view and/or modify sensitive data.
The following versions of Pyxis MedStation and Anesthesia (PAS) ES Systems, are affected:
A restricted desktop environment escape vulnerability exists in the kiosk mode functionality of affected devices. Specially crafted inputs could allow the user to escape the restricted environment, resulting in access to sensitive data.
CVE-2020-10598 has been assigned to this vulnerability. A CVSS v3 base score of 6.8 has been calculated; the CVSS vector string is (AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
BD reported this vulnerability to CISA.
BD recommends the following mitigations and compensating controls in order to reduce risk associated with this vulnerability:
Additionally, BD is in the process of deploying a security update that strengthens kiosk mode to limit currently known methods of kiosk escape in Pyxis MedStation and Pyxis Anesthesia (PAS) ES System Version 1.6.1. Access to tools for viewing or manipulating local resources will be restricted.
For more information on this issue, please see the associated BD product security bulletin on the BD website.
