Risk Evaluation
A security vulnerability was discovered in the PLC Designer V4 in the version 4.0.0 where the programmer of a Controller can set a password for the connected device. Here it is possible in an interface of the PLC Designer V4 for the programmer to enter a password for the Device. There is a special constellation where the password entered appears in plain text. Only the display in the tool is affected and not the management of the password on the device. This vulnerability of PLC Designer V4 only occurs in combination with the devices c430 controller, c520 controller and c550 controller and not in combination with other devices, as this functionality is only used here. It is generally recommended that all users update to 4.0.1, but especially all users who operate PLC Designer V4 in combination with the controllers mentioned.
Zusammenfassung der Gegenmaßnahmen
This vulnerability has been fixed in the new version. All users are strongly recommended to use the new version 4.0.1.
