Elad Luz of CyberMDX discovered this vulnerability, and BD reported this
vulnerability to NCICC.
BD reports that this vulnerability cannot be performed if the device is
connected to an Alaris Gateway Workstation docking station. Also, an attacker
cannot switch the device on remotely, and no PHI or PII can be accessed by
exploiting this vulnerability.
BD recommends the following mitigations and compensating controls in order to
reduce risk associated with this vulnerability:
o This attack utilizes a known vulnerability in terminal servers. Users who
utilize terminal servers should understand that terminal server use is not
o Users should ensure they are operating these devices in a segmented
network environment or as a stand-alone device.
o Users should utilize connections via the Alaris Gateway Workstation
docking station, which would inactivate the remote control feature.

NCCIC recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability. Specifically, users should:
o Minimize network exposure for all control system devices and/or systems,
and ensure that they are not accessible from the Internet.
o Locate control system networks and remote devices behind firewalls, and
isolate them from the business network.
o When remote access is required, use secure methods, such as Virtual
Private Networks (VPNs), recognizing that VPNs may have vulnerabilities
and should be updated to the most current version available. Also
recognize that VPN is only as secure as the connected devices.
NCCIC reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
NCCIC also provides a section for control systems security recommended
practices on the ICS-CERT web page. Several recommended practices are
available for reading and download, including Improving Industrial Control
Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly
available on the ICS-CERT website in the Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to NCCIC for
tracking and correlation against other incidents.
No known public exploits specifically target this vulnerability.
