3.2 VULNERABILITY OVERVIEW

3.2.1    NOT USING PASSWORD AGING CWE-262

Specific BD Pyxis products were installed with default credentials and may still operate with these credentials. There may be scenarios where BD Pyxis products are installed with the same default local operating system credentials or domain-joined server(s) credentials that may be shared across product types. Threat actors could exploit this vulnerability to gain privileged access to the underlying file system and exploit or gain access to ePHI or other sensitive information.

CVE-2022-22767 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been assigned; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

3.3 BACKGROUND

• CRITICAL INFRASTRUCTURE SECTORS: Healthcare and Public Health
• COUNTRIES/AREAS DEPLOYED: Worldwide
• COMPANY HEADQUARTERS LOCATION: United States

3.4 RESEARCHER

BD voluntarily reported this vulnerability through the CISA coordinated vulnerability disclosure program.

4. MITIGATIONS

BD is currently strengthening credential management capabilities in BD Pyxis products. Service personnel are working with users whose domain-joined server(s) credentials require updates.

BD is piloting a credential management solution initially targeted for specific BD Pyxis product versions and will allow for improved authentication management practices with specific local operating system credentials. Changes needed for installation, upgrade, or to applications are being evaluated as remediations.

Additionally, BD recommends the following compensating controls for users of BD Pyxis products utilizing default credentials:

• Limit physical access to only authorized personnel.
• Tightly control management of system passwords provided to authorized users.
• Monitor and log network traffic attempting to reach the affected products for suspicious activity.
• Isolate affected products in a secure VLAN or behind firewalls with restricted access that only permits communication with trusted hosts in other networks, when needed.

For more information on this issue, please see the associated BD product security bulletin on the BD website.
