Easergy Builder

Notes

General Security Recommendations
We strongly recommend the following industry cybersecurity best practices. https://www.se.com/us/en/download/document/7EN52-0390/ * Locate control and safety system networks and remote devices behind firewalls and isolate 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 for that device. * Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, 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 the intended network to connect to the safety or control networks without proper sanitation. * Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet. * 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 the most current version available. Also, understand that VPNs are only as secure as the connected devices. For more information refer to the Schneider Electric Recommended Cybersecurity Best Practices document.
For More Information

Overview
Researchers from Rostelecom-Solar have made Schneider Electric aware of multiple vulnerabilities affecting the company’s Easergy Builder configuration tool. Schneider Electric has worked closely with Ilya Karpov and Evgeniy Druzhinin of Rostelecom-Solar to remediate the vulnerabilities and appreciates their collaboration and commitment to transparency. The vulnerabilities have been remediated via a free software update, which is available immediately by contacting Schneider Electric’s Customer Care Center. Access to the customer’s network is required for the majority of the disclosed vulnerabilities to be exploited. Therefore, if the customer’s network is well protected and monitored for intrusion, and care is taken to obtain software updates from a trusted source, the general risk of exploitation can be substantially minimized. Schneider Electric encourages customers to upgrade to the new software as soon as possible. The company further encourages customers to ensure any firmware files used to update the device are acquired from trusted sources; to operate the products on properly segmented control networks; to adequately secure any workstation that has been configured to have access to the product; and to follow the remediation and general security recommendations below.
