CVE-2017-16690
HighSummary
A malicious DLL preload attack is possible on NwSapSetup and the self-extracting installation program for SAP Plant Connectivity 2.3 and 15.0. The program may load system DLLs like DWMAPI.dll from the folder it resides in instead of from system folders.
Risk Assessment
The organization may be at risk of executing malicious code if a DLL with the same name as the system DLL is present in the same folder as the executable. This could lead to serious security breaches.
Recommendation
It is recommended that IT administrators ensure that system DLLs are loaded only from system folders and monitor and control the contents of folders containing executable files.

Original NVD description (English source)
A malicious DLL preload attack possible on NwSapSetup and Installation self-extracting program for SAP Plant Connectivity 2.3 and 15.0. It is possible that SAPSetup / NwSapSetup.exe loads system DLLs like DWMAPI.dll (located in your Syswow64 / System32 folder) from the folder the executable is in and not from the system location. The desired behavior is that system dlls are only loaded from the system folders. If a dll with the same name as the system dll is located in the same folder as the executable, this dll is loaded and code is executed.
