Summary
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.
Exploit prediction
1.06% chance of exploitation in the next 30 days, higher than 64% of all scored CVEs (FIRST EPSS, 2026-11-09).
