Wireless keys are stored in plain text on version 5 of the Hospira LifeCare PCA Infusion System. According to Hospira, version 3 of the LifeCare PCA Infusion System is not indicated for wireless use, is not shipped with wireless capabilities, and should not be modified to be used in a wireless capacity in a clinical setting. Hospira has developed a new version of the PCS Infusion System, version 7.0 that addresses the identified vulnerabilities. Version 7.0 has Port 20/FTP and Port 23/TELNET closed by default to prevent unauthorized access.

Because the information is stored in cleartext (i.e., unencrypted), attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information. When organizations adopt cloud services, it can be easier for attackers to access the data from anywhere on the Internet. In some systems/environments such as cloud, the use of “double encryption” (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
