Remediations
Mitigation
Delta Electronics is aware of the vulnerability and is currently working on a fix.
Mitigation
Delta Electronics recommends users apply the following workarounds:
Mitigation
Do not open unsolicited project files: Do not open or import unsolicited project files, untrusted Internet links, or unexpected attachments from emails, network shares, or USB drives. Always verify the source of the file before opening it.
Mitigation
Avoid running as administrator: Do not use the “Run as Administrator” option when launching the software. Running the software with standard user privileges effectively limits the damage of potential malicious code.

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability.
Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
