为什么 CreateProcessWithTokenW 因 ERROR_ACCESS_DENIED 而失败

Question

我对 CreateProcessWithTokenW 的调用因访问被拒绝而失败。有什么想法可以调试吗？

此处调用 CreateProcessWithTokenW：https://github.com/fschwiet/PShochu/blob/master/PShochu/PInvoke/NetWrappers/ProcessUtil.cs

目前我正在为当前进程使用访问令牌，最终我将使用来自另一个用户的令牌。现在我使用https://github.com/fschwiet/PShochu/blob/master/PShochu/PInvoke/NetWrappers/AccessToken.cs 来获取访问令牌。

如果要调试，请下拉源代码并运行 build_and_test.ps1。错误堆栈是：

1) Test Error : PShochu.Tests.can_run_remote_interactive_tasks, given a psake script which writes the current process id to output, when that script is invoked interactively, then the script succeeds
   System.ComponentModel.Win32Exception : Access is denied

后来的更新：我在一些文档中看到需要额外的权限 (http://msdn.microsoft.com/en-us/library/aa374905%28v=vs.85%29.aspx)。我无法通过测试来验证我是否拥有这些单独的证券（它们在 secpol.msc 重启前设置）

SE_ASSIGNPRIMARYTOKEN_NAME  "Replace a process level token"
SE_TCB_NAME "Act as part of the operatin system"
SE_INCREASE_QUOTA_NAME  "Adjust memory quotas for a process"

这些测试不断告诉我我没有在 UI 中设置的权限，https://github.com/fschwiet/PShochu/blob/master/PShochu.Tests/verify_privileges.cs

Answer 1

通过反复试验，我发现您传递给 CreateProcessWithTokenW() 的令牌需要以下访问标志（至少在 Windows 7 SP1 64 位上）：

• TOKEN_ASSIGN_PRIMARY
• TOKEN_DUPLICATE
• TOKEN_QUERY
• TOKEN_ADJUST_DEFAULT
• TOKEN_ADJUST_SESSIONID

最后两个粗体字在 CreateProcessWithTokenW() 的文档中根本没有提及。

编辑：以下代码对我来说很好（运行提升时）：

HANDLE hToken = NULL;
if(OpenProcessToken(GetCurrentProcess(), TOKEN_DUPLICATE, &hToken))
{
    HANDLE hDuplicate = NULL;
    if(DuplicateTokenEx(hToken, TOKEN_ASSIGN_PRIMARY | TOKEN_DUPLICATE | TOKEN_QUERY | TOKEN_ADJUST_DEFAULT | TOKEN_ADJUST_SESSIONID, NULL, SecurityImpersonation, TokenPrimary, &hDuplicate))
    {
        TCHAR szCommandLine[MAX_PATH];
        _tcscpy_s(szCommandLine, MAX_PATH, _T("C:\\Windows\\system32\\notepad.exe"));
        STARTUPINFO StartupInfo;
        ZeroMemory(&StartupInfo, sizeof(STARTUPINFO));
        StartupInfo.cb = sizeof(STARTUPINFO);
        PROCESS_INFORMATION ProcessInformation;
        ZeroMemory(&ProcessInformation, sizeof(PROCESS_INFORMATION));
        if(CreateProcessWithTokenW(hDuplicate, LOGON_WITH_PROFILE, NULL, szCommandLine, 0, NULL, NULL, &StartupInfo, &ProcessInformation))
        {
            WaitForSingleObject(ProcessInformation.hProcess, INFINITE);
            CloseHandle(ProcessInformation.hThread);
            ProcessInformation.hThread = NULL;
            CloseHandle(ProcessInformation.hProcess);
            ProcessInformation.hProcess = NULL;
        }
        CloseHandle(hDuplicate);
        hToken = hDuplicate;
    }
    CloseHandle(hToken);
    hToken = NULL;
}
