Thank you very much for your continuous use of Pro-face products.

As you are aware, cyber security is changing the business climate for control systems. Digital Electronics has become aware of cyber security vulnerabilities in Pro-Server EX and WinGP on PC for HMI GP series. The vulnerabilities can be exposed in the event of a targeted cyber-attack. An attacker would use a masqueraded node that would use a specially crafted packet sent to Pro-Server EX.

We take these issues seriously and have created the following workaround and solution.

We recommend customers take defensive measures to minimize the exploitation risk. Specifically, customers should do the following:
  1. Review all network configurations for control system devices.
    - Remove unnecessary PC(s) from control system networks
    - Remove unnecessary applications from control system networks
  2. Minimize network exposure for all control system devices. Control system devices should not have a direct connection to the Internet
  3. Locate control system networks and devices behind firewalls.  Isolate the control system from the business network.
  4. When remote access to a control system is required, employ secure methods, such as Virtual Private Networks (VPNs). However, our customers must recognize that a VPN is only as secure as the connected devices.
