Fixes

Solution

Ruijie reports that the issues have been fixed on the cloud and no action is needed by end users. However, CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as: * Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet https://www.cisa.gov/uscert/ics/alerts/ICS-ALERT-10-301-01 . * 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.
