CVE-2021-44768
6.1 (Medium)
CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:L
CWE-125 - Out-of-bounds Read
Mitigation Delta Electronics recommends users upgrade to the latest available patch. https://downloadcenter.deltaww.com/en-US/Download…
Mitigation Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.
Mitigation Locate control system networks and remote devices behind firewalls and isolate them from the business network.
Mitigation When remote access is required, use 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 its connected devices.
