Summary

Affected Software

Weaknesses

• CWE-134: CWE-134: Use of Externally-Controlled Format String

Workarounds

Moxa recommends users to implement the following mitigations if necessary:

• 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.
