Schneider Electric is establishing a remediation plan for all future versionsof SCADAPack Workbench that will include a fix for this vulnerability. We
will update this document when the remediation is available. Until then,customers should immediately apply the following mitigations to reduce
the risk of exploit:• Run SCADAPack Workbench as a User, not as an Administrator,
to minimize the impact of malicious code on the infected system.
• Do not open untrusted files with SCADAPack Workbench.
• Provide training and awareness programs to educate users on thewarning signs of a phishing or social engineering attack.
• Employ Data Loss Prevention tools to help mitigate risk.
• Restrict communication from workstations running SCADAPack
Workbench to external systems.

General Security Recommendations
We strongly recommend the following industry cybersecurity best practices.
•••
•
•
•
•

Locate control and safety system networks and remote devices behind firewalls andisolate them from the business network.
Install physical controls so no unauthorized personnel can access your industrial control
and safety systems, components, peripheral equipment, and networks.
Place all controllers in locked cabinets and never leave them in the “Program” mode.
Never connect programming software to any network other than the network intended forthat device.
Scan all methods of mobile data exchange with the isolated network such as CDs, USBdrives, etc. before use in the terminals or any node connected to these networks.
Never allow mobile devices that have connected to any other network besides theintended network to connect to the safety or control networks without proper sanitation.
Minimize network exposure for all control system devices and systems and ensure thatthey are not accessible from the Internet.

Schneider Electric Security Notification•When remote access is required, use secure methods, such as Virtual Private Networks(VPNs). Recognize that VPNs may have vulnerabilities and should be updated to themost current version available. Also, understand that VPNs are only as secure as theconnected devices.
