According to Baxter, software updates to disable Telnet and FTP (CVE-2022-26392) are in process. Software updates addressing the format string attack (CVE-2022-26393) are included in WBM version 20D30 and all other WBM versions authentication is already available in Spectrum IQ (CVE-2022-26394). Instructions to erase all data and settings on WBMs and pumps before decommissioning and transferring to other facilities (CVE-2022-26390) are in process for incorporation into the Spectrum Operator's Manual.
