Official description
Specific BD Pyxis™ products were installed with default credentials and may presently 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. If exploited, threat actors may be able to gain privileged access to the underlying file system and could potentially exploit or gain access to ePHI or other sensitive information.

The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
