Unquoted Service Path Check Result: Vulnerable service path found: c:\program files (x86)\grasssoft\macro expert\MacroService.exe

Simply load the cna file and type "privcheck" If you want to compile by yourself you can use: make all or x86_64-w64-mingw32-gcc -c cfile.c -o ofile.o

If you want to look for just one misconf you can use object file with "inline-execute" for example inline-execute /path/tokenprivileges.o
