RunPE: Arguments do not get passed

When running a base64 encoded file via command line, arguments are not appropriately passed to the execution of the command of some binaries.

I have used net.exe just fine, however Mimikatz and CheekyBlinders both do not get arguments passed appropriately.

RunPE Version: Latest
OS: Windows 10
Build: OS Version: 10.0.19045 N/A Build 19045

Example running Mimikatz (latest):

As you can see, the execution of the PE works, however the arguments passed are not passed on to the PE.

I am using our C2 to wrap this functionality and passing the arguments, however they do not get executed.

I have also tried the CheekyBlinders (https://github.com/br-sn/CheekyBlinder) PE file, which results in the same issue of arguments not being passed to the PE binary.

You can see executing directly from the file works in both cases

Notice the highlighted area, where Mimikatz is being passed the Argument 0 instead of just coffee and exit

CheekyBlinders:

Note CheekyBlinders doesn’t even execute correctly, however this may because again of the argv[0] being passed instead of argv[1]
