進程提權

</pre><pre>

HANDLE tokenHandle;
//獲得令牌句柄
BOOL bRet = OpenProcessToken(GetCurrentProcess(), TOKEN_ALL_ACCESS, &tokenHandle);
if (bRet){
	TOKEN_PRIVILEGES tokenPri;tokenPri.PrivilegeCount = 1;//tokenPri.Privileges數組的大小
	tokenPri.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;//開啓權限Luid所標識的權限
	bRet = LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &tokenPri.Privileges[0].Luid);//獲取權限的標識Luid
	if (bRet){
		bRet = AdjustTokenPrivileges(tokenHandle, FALSE, &tokenPri, sizeof(tokenPri), NULL, NULL);//修改權限}CloseHandle(tokenHandle);
	}
}
return bRet;//提權是否成功

OpenProcessToken原型：

BOOL WINAPI OpenProcessToken(
  _In_   HANDLE ProcessHandle,<span style="white-space:pre">	</span>// 進程句柄
  _In_   DWORD DesiredAccess,<span style="white-space:pre">	</span>// 想要獲得的訪問權限
  _Out_  PHANDLE TokenHandle<span style="white-space:pre">	</span>// 返回的令牌句柄
);

  _In_opt_   PTOKEN_PRIVILEGES NewState,//指向TOKEN_PRIVILEGES結構體的指針
  _In_       DWORD BufferLength,<span style="white-space:pre">	</span>//sizeof（NewState）
  _Out_opt_  PTOKEN_PRIVILEGES PreviousState,<span style="white-space:pre">	</span>// 指向用來保存修改前的TOKEN_PRIVILIGES的結構體，若不想保存修改前的權限，可以爲NULL
  _Out_opt_  PDWORD ReturnLength<span style="white-space:pre">	</span>// 指向用來保存<span style="font-family: Arial;">PreviousState大小的DWORD的指針</span>
