Sigma Spectrum Infusion System v's6.x (model 35700BAX) and Baxter Spectrum Infusion System Version(s) 8.x (model 35700BAX2) at the application layer uses an unauthenticated clear-text communication channel to send and receive system status and operational data. This could allow an attacker that has circumvented network security measures to view sensitive non-private data or to perform a man-in-the-middle attack.
