Solution:

  • Delta Electronics has fixed the reported vulnerabilities in Version 1.08.02.004. Users should contact Delta customer service or a Delta representative for this release, as it will not be released publicly. Delta is working on a public release that will include these fixes and other features on June 30, 2022. Delta also suggests users: Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet. Locate control system networks and remote devices behind firewalls and isolate them from the business network. Use an application firewall that can detect attacks against “Path Traversal” and “SQL Injection” weakness. Never connect programming software to any network other than the network intended for that device. When remote access is required, use secure methods, such as virtual private networks (VPNs), recognizing a VPN is only as secure as its connected devices
