要實現權限提升,可以使用OpenProcessToken函數來獲取當前進程的訪問令牌,然后使用AdjustTokenPrivileges函數來更改該令牌的權限。
具體步驟如下:
以下是一個簡單的示例代碼:
#include <windows.h>
#include <iostream>
int main()
{
HANDLE hToken;
if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
{
std::cout << "OpenProcessToken failed: " << GetLastError() << std::endl;
return 1;
}
LUID luid;
if (!LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &luid))
{
std::cout << "LookupPrivilegeValue failed: " << GetLastError() << std::endl;
return 1;
}
TOKEN_PRIVILEGES tp;
tp.PrivilegeCount = 1;
tp.Privileges[0].Luid = luid;
tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
if (!AdjustTokenPrivileges(hToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), NULL, NULL))
{
std::cout << "AdjustTokenPrivileges failed: " << GetLastError() << std::endl;
return 1;
}
if (GetLastError() == ERROR_NOT_ALL_ASSIGNED)
{
std::cout << "The specified privilege is not held by the client." << std::endl;
return 1;
}
std::cout << "Privilege escalated successfully!" << std::endl;
CloseHandle(hToken);
return 0;
}
在這個示例中,我們將當前進程的權限提升為調試權限(SE_DEBUG_NAME),你可以根據需要修改要提升的權限。記得在程序結束時關閉訪問令牌的句柄。
