进程提权

</pre><pre>

HANDLE tokenHandle;
//获得令牌句柄
BOOL bRet = OpenProcessToken(GetCurrentProcess(), TOKEN_ALL_ACCESS, &tokenHandle);
if (bRet){
	TOKEN_PRIVILEGES tokenPri;tokenPri.PrivilegeCount = 1;//tokenPri.Privileges数组的大小
	tokenPri.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;//开启权限Luid所标识的权限
	bRet = LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &tokenPri.Privileges[0].Luid);//获取权限的标识Luid
	if (bRet){
		bRet = AdjustTokenPrivileges(tokenHandle, FALSE, &tokenPri, sizeof(tokenPri), NULL, NULL);//修改权限}CloseHandle(tokenHandle);
	}
}
return bRet;//提权是否成功

OpenProcessToken原型：

BOOL WINAPI OpenProcessToken(
  _In_   HANDLE ProcessHandle,<span style="white-space:pre">	</span>// 进程句柄
  _In_   DWORD DesiredAccess,<span style="white-space:pre">	</span>// 想要获得的访问权限
  _Out_  PHANDLE TokenHandle<span style="white-space:pre">	</span>// 返回的令牌句柄
);

DesiredAccess的取值及其含义（不太清楚的话直接用TOKEN_ALL_ACCESS就行了）

AdjustTokenPrivileges原型：

BOOL WINAPI AdjustTokenPrivileges(
  _In_       HANDLE TokenHandle,<span style="white-space:pre">	</span>//令牌句柄
  _In_       BOOL DisableAllPrivileges,<span style="white-space:pre">	</span>//为FALSE时表示禁用所有权限，为TRUE时表示用NewState所指向的结构体来修改权限
  _In_opt_   PTOKEN_PRIVILEGES NewState,//指向TOKEN_PRIVILEGES结构体的指针
  _In_       DWORD BufferLength,<span style="white-space:pre">	</span>//sizeof（NewState）
  _Out_opt_  PTOKEN_PRIVILEGES PreviousState,<span style="white-space:pre">	</span>// 指向用来保存修改前的TOKEN_PRIVILIGES的结构体，若不想保存修改前的权限，可以为NULL
  _Out_opt_  PDWORD ReturnLength<span style="white-space:pre">	</span>// 指向用来保存<span style="font-family: Arial;">PreviousState大小的DWORD的指针</span>
);

_TOKEN_PRIVILEGES 定义：

typedef struct _TOKEN_PRIVILEGES {
  ULONG               PrivilegeCount; //Privileges数组的大小，一般为1
  LUID_AND_ATTRIBUTES Privileges[ANYSIZE_ARRAY];
} TOKEN_PRIVILEGES, *PTOKEN_PRIVILEGES;

_LUID_AND_ATTRIBUTES 定义：

typedef struct _LUID_AND_ATTRIBUTES {
  LUID  Luid;<span style="white-space:pre">	</span>//权限的唯一标识

属性	描述
SE_PRIVILEGE_ENABLED_BY_DEFAULT	特权默认启用
SE_PRIVILEGE_ENABLED	特权启用.
SE_PRIVILEGE_USED_FOR_ACCESS	特权被用来访问一个对象或服务。 这个标志 被用于 标识有关特权，因为 通过一组客户端应用程序，可能包含不必要的特权

LookupPrivilegeValue原型：

BOOL WINAPI LookupPrivilegeValue(
  _In_opt_  LPCTSTR lpSystemName,//指向系统名称的字符串的指针，一般为NULL，表示从本地系统获取查找权限的名称，
  _In_      LPCTSTR lpName,	 //权限的名称
  _Out_     PLUID lpLuid	 //返回的LUID的指针
