What to do
Solution: Moxa has developed an appropriate solution to address the vulnerability. The solution for the affected product is shown below. * MXsecurity: Please Upgrade to the firmware version 2.2.0 or higher via the Moxa Software Licensing Portal https://netsecuritylicense.moxa.com/Account/Login
Workaround: * Minimize network exposure to ensure the device is not accessible from the Internet. * When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). * The starting point of all the above vulnerabilities is from the web service, so it is suggested to disable web service temporarily if you completed configuration to prevent further damages from these vulnerabilities until installed patch or updated firmware.
