capt-meelo / ntcreateuserprocess Goto Github PK

First I'd like to thank you for your great article! It was really interesting and inspiring to read and follow.

Next, I'd like to report kind of an interesting behaviour, maybe helpful for anyone who comes with a same problem.

I've tried to launch different programs and noticed that it's impossible to start any EXE from outside System32 folder. E.g. you can't launch \\??\\C:\\Windows\\notepad.exe, NtCreateUserProcess returns STATUS_OBJECT_PATH_INVALID. Interestingly, on Wine the same executable works and launches notepad successfully, so I think it has to do something with very deep NT internal stuff.

Hello!
CreateProcess don't work, write "invalid parameter". Can you give me .exe for debug?? Windows 10 x64

hello,
sorry if I open an issue for discussion.

I am studying NtCreateUserProcess for practice, work and personal study.Thanks to your contribution I was able to understand a few things and I thank you for your article and code.

After banging my head for two days, however, I was unable to do one thing:
I would like to start a terminal application within the same console but instead it always opens a new window.
An example to try is if I run "powershell", I would like it to run in the same context as the execution console.

With your experience, do you have something in mind where I could look?

This project is very cool,But my attempt to start a process with arguments failed,Even though I didn't succeed after reading your blog posts

int main()
{


	// Path to the image file from which the process will be created
	UNICODE_STRING NtImagePath;
	RtlInitUnicodeString(&NtImagePath, (PWSTR)L"\\??\\C:\\Windows\\System32\\cmd.exe");

	// Create the process parameters
	PRTL_USER_PROCESS_PARAMETERS ProcessParameters = NULL;

	UNICODE_STRING us;
	RtlInitUnicodeString(&ProcessParameters->CommandLine, (PWSTR)L"\C:\\Windows\\System32\\cmd.exe /c calc.exe");

	RtlCreateProcessParametersEx(&ProcessParameters, &NtImagePath, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, RTL_USER_PROCESS_PARAMETERS_NORMALIZED);

	// Initialize the PS_CREATE_INFO structure
	PS_CREATE_INFO CreateInfo = { 0 };
	CreateInfo.Size = sizeof(CreateInfo);
	CreateInfo.State = PsCreateInitialState;

	// Initialize the PS_ATTRIBUTE_LIST structure
	PPS_ATTRIBUTE_LIST AttributeList = (PS_ATTRIBUTE_LIST*)RtlAllocateHeap(RtlProcessHeap(), HEAP_ZERO_MEMORY, sizeof(PS_ATTRIBUTE));
	AttributeList->TotalLength = sizeof(PS_ATTRIBUTE_LIST) - sizeof(PS_ATTRIBUTE);
	AttributeList->Attributes[0].Attribute = PS_ATTRIBUTE_IMAGE_NAME;
	AttributeList->Attributes[0].Size = NtImagePath.Length;
	AttributeList->Attributes[0].Value = (ULONG_PTR)NtImagePath.Buffer;

	// Create the process
	HANDLE hProcess, hThread = NULL;
	NtCreateUserProcess(&hProcess, &hThread, PROCESS_ALL_ACCESS, THREAD_ALL_ACCESS, NULL, NULL, NULL, NULL, ProcessParameters, &CreateInfo, AttributeList);

	// Clean up
	RtlFreeHeap(RtlProcessHeap(), 0, AttributeList);
	RtlDestroyProcessParameters(ProcessParameters);
}

According to the article, you only need to set the CommandLine field of ProcessParameters as a parameter, but I failed. Could you please help me? Thank you very much！
