Baxter SIGMA Spectrum Infusion System version 6.05 (model 35700BAX) with wireless battery module (WBM) version 16 is remotely accessible via Port 22/SSH without authentication. A remote attacker may be able to make unauthorized configuration changes to the WBM, as well as issue commands to access account credentials and shared keys. Baxter asserts that this vulnerability only allows access to features and functionality on the WBM and that the SIGMA Spectrum infusion pump cannot be controlled from the WBM. Baxter has released a new version of the SIGMA Spectrum Infusion System, Version 8, which incorporates hardware and software changes.
