3.2 VULNERABILITY OVERVIEW

3.2.1    USE OF HARD-CODED CREDENTIALS CWE-798

The affected product is vulnerable due to the use of hard-coded credentials, which may allow threat actors to gain access to the underlying file system and exploit application files for information that could be used to decrypt application credentials or gain access to electronic protected health information (ePHI) or other sensitive information. Credentials are BD managed and are not visible to or used by customers to access or use BD Pyxis devices.

CVE-2022-22766 has been assigned to this vulnerability. A CVSS v3 base score of 7.0 has been calculated; the CVSS vector string is (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H).

3.3 BACKGROUND

  • CRITICAL INFRASTRUCTURE SECTORS: Healthcare and Public Health
  • COUNTRIES/AREAS DEPLOYED: Worldwide

3.4 RESEARCHER

BD voluntarily reported this vulnerability to CISA.

4. MITIGATIONS

BD is in the process of strengthening credential management capabilities in BD Pyxis devices.

Additionally, BD recommends the following compensating controls for users of BD Pyxis products that utilize the hard-coded credentials:

  • Limit physical access to the device to only authorized personnel.
  • Tightly control management of BD Pyxis system credentials provided to authorized users.
  • 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.
  • Monitor and log all network traffic attempting to reach the affected products for suspicious activity.
  • Work with a BD support team to ensure all patching and virus definitions are up to date. The Pyxis Security Module for automated patching and virus definition management is provided to all accounts.
