我调用CreateProcessWithTokenW,但是访问被拒绝失败。有任何想法如何调试这个?
对CreateProcessWithTokenW的调用在这里:https://github.com/fschwiet/PShochu/blob/master/PShochu/PInvoke/NetWrappers/ProcessUtil.cs
现在我正在为当前进程使用访问令牌,最终我将使用来自其他用户的令牌。现在,我正在使用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

后期更新:我在某些文档中看到需要其他权限(http://msdn.microsoft.com/en-us/library/aa374905%28v=vs.85%29.aspx)。我无法通过测试来验证我有这些个人证券(它们是在重启前的secpol.msc中设置的)
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"
这些测试一直告诉我,我没有在UI中设置的权限,https://github.com/fschwiet/PShochu/blob/master/PShochu.Tests/verify_privileges.cs
答案 0 :(得分:13)
通过反复试验,我发现传递给CreateProcessWithTokenW()的令牌需要以下访问标志(至少在Windows 7 SP1 64位上):
在CreateProcessWithTokenW()的文档中完全没有提到粗体的最后两个。
编辑:以下代码适用于我(在提升时运行):
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;
}
