A vulnerability has been discovered in the fdtCONTAINER component and application by M&M Software GmbH.
As this software is part of the Weidmüller FDT/DTM Software with WI Manager, this Weidmueller software is affected by the above vulnerability as well.

The fdtCONTAINER component exchanges binary data blobs with the WI Manager. The WI Manager saves these binary data blobs into a project file.

If an attacker gets write access to the project file, the project file can be manipulated to contain malicious code.



A critical vulnerability has been discovered in the fdtCONTAINER component by M&M Software GmbH used by PACTware.
While de-serializing PACTware 5 project files (loading PW5 files) the vulnerability can be exploited to execute arbitrary code.



The fdtCONTAINER component is integrated into an application (host application). The fdtCONTAINER application is a specific host application which integrates the fdtCONTAINER component.

The fdtCONTAINER component exchanges binary data blobs with such a host application. Typically, the host application saves these binary data blobs into a project storage (project file or a project database).

To manipulate the data inside the project storage, the attacker needs write access to this project storage. Additionally, the manipulated project needs to be opened by the host application. It depends on the host application whether opening the project requires a user action or not. In
fdtCONTAINER applications, the user has to open the manipulated project file manually.

In the case of opening a stored project, the deserialization of the manipulated data can be exploited.
