Moxa has developed appropriate solutions to address the vulnerabilities. The solutions for affected products are shown below.
Moxa recommends users follow CISA recommendations. Users should:
Reduce network exposure by ensuring that all control system devices and systems are not accessible from the Internet.
Place control system networks and remote devices behind firewalls, isolating them from business networks.
When remote access is necessary, employ secure methods such as Virtual Private Networks (VPNs). It is important to note that VPNs may have vulnerabilities and should be kept up to date with the latest available version. Remember that the security of a VPN depends on the security of its connected devices.
