The patch can be downloaded from the CoDeSys Download Center http://www.codesys.com/download.html . CoDeSys Version 3.X is not affected by these vulnerabilities.
Workaround: 3S also recommends the usage of standard security methods like firewalls or virtual private network (VPN) access to prevent unauthorized access to the controller.
