CVE-2017-16690
A malicious DLL preload attack possible on NwSapSetup and Installation self-extracting program for SAP Plant Connectivity 2.3 and 15.0.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.06%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
