VULNERABILITY CHARACTERIZATION
VULNERABILITY OVERVIEW
INSUFFICIENTLY PROTECTED CREDENTIALS[a]
An unauthorized user with physical access to an Alaris 8000 PC unit may be
able to obtain unencrypted wireless network authentication credentials and
other sensitive technical data by disassembling an Alaris 8000 PC unit and
accessing the devices flash memory. The Alaris 8000 PC unit stores wireless
network authentication credentials and other sensitive technical data on
internal flash memory. Accessing the internal flash memory of the affected
device would require special tools to extract data and carrying out this
attack at a healthcare facility would increase the likelihood of detection.
CVE-2016-8375[b] has been assigned to this vulnerability. A CVSS v3 base score
of 4.9 has been assigned; the CVSS vector string is
(AV:P/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N).[c]
VULNERABILITY DETAILS
EXPLOITABILITY
This vulnerability could not be exploited remotely.
EXISTENCE OF EXPLOIT
No known public exploits specifically target this vulnerability.
DIFFICULTY
An attacker with low skill would be able to exploit this vulnerability.
MITIGATION
BD has not developed a product fix to address the vulnerability, but has
issued compensating controls to reduce the risk of exploitation. BD recommends
that users apply the following compensating controls:
Users are advised to exercise diligence in implementing a physical asset
management program that involves tracking and inventorying equipment.
Users are advised to follow procedures for clearing wireless network
authentication credentials on the Alaris PC unit if the device is to be
removed or transported from the facility. These procedures are outlined in the
Alaris System Maintenance Software User Manual.

management program that involves tracking and inventorying equipment,
particularly for Alaris PC units that store credentials in removable flash
memory.
Users are advised to follow procedures for clearing wireless network
authentication credentials on the Alaris PC unit if the device is to be
removed or transported from the facility. These procedures are outlined in the
Alaris System Maintenance Software User Manual.
Users are advised to change wireless network authentication credentials
regularly and immediately if there is evidence of unauthorized physical access
to an Alaris device at their facility.
Users are strongly encouraged to consider security policy in which wireless
credentials are not configured for the Alaris PC unit if wireless networking
functionality is not being utilized for operation. This will remediate these
vulnerabilities for nonwireless users.
Users may choose to implement Access Control Lists that restrict device access
to specific media access control (MAC) and IP addresses, ports, protocols, and
services.
Users may choose to place Alaris PC units on an isolated network with
dedicated service set identifier (SSID) to reduce the impact of compromised
wireless network credentials. In all cases, security best practice prescribes
frequent changing of SSID and wireless authentication credentials.
