The HIPAA configuration interface in GE Healthcare Optima MR360 has a password of (1) operator for the root account, (2) adw2.0 for the admin account, and (3) adw2.0 for the sdc account, which has unspecified impact and attack vectors. NOTE: it is not clear whether these passwords are default, hardcoded, or dependent on another system or product that requires a fixed value.
