BD recommends the following mitigations and compensating controls in order to reduce risk associated with this vulnerability:
• This attack utilizes a known vulnerability in terminal servers. Users who utilize terminal servers should understand that terminal server use is not supported.
• Users should ensure they are operating these devices in a segmented network environment or as a stand-alone device.
• Users should utilize connections via the Alaris Gateway Workstation docking station, which would inactivate the remote control feature.
