[英]How to get the handle of a registry key without even read permission
I'm trying to call this function to take owner for a key. 我正在尝试调用此函数以获取所有者作为密钥。
[DllImport("Advapi32.dll", CharSet = CharSet.Auto)]
public extern static int SetSecurityInfo(IntPtr hKeySrc, SE_OBJECT_TYPE lpSubKey, SECURITY_INFORMATION securityInfo, IntPtr psidOwner, IntPtr psidGroup, IntPtr pDacl, IntPtr pSacl);
However, to call this function, I first need a handle to the key (IntPtr hKeysrc). 但是,要调用此函数,我首先需要键的句柄(IntPtr hKeysrc)。 Before I use these function to get the handle.
在使用这些功能获取句柄之前。
RegistryKey key = root.OpenSubKey(keyName);
private static IntPtr GetRegistryKeyHandle(RegistryKey registryKey)
{
IntPtr ret = IntPtr.Zero;
try
{
Type registryKeyType = typeof(RegistryKey);
System.Reflection.FieldInfo fieldInfo =
registryKeyType.GetField("hkey", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
SafeHandle handle = (SafeHandle) fieldInfo.GetValue(registryKey);
ret = handle.DangerousGetHandle();
}
catch (Exception ex)
{
LogError("GetRegistryKeyHandle ERROR:" + ex.ToString());
}
return ret;
}
But now the key that I'm targeting only has permission to System account! 但是现在,我定位的密钥仅具有系统帐户的权限!
When I try to open permissions in regedit for the key, I get the error You do not have permission to view the current permission settings, but you can make permission changes. 当我尝试在注册表编辑器中打开密钥的权限时,收到错误消息您没有权限查看当前的权限设置,但是可以进行权限更改。
I don't even have read permission to the key. 我什至没有对该密钥的读取权限。 Then the method I used to get handle will failed with unauthorized error.
然后,我用来获取方法的方法将因未授权错误而失败。
How can I get a handle to the key in this case? 在这种情况下,如何获得钥匙的手柄? Actually, regedit can do it.
实际上,regedit可以做到。 So I think there may an API can do it.
所以我认为可能有一个API可以做到。 But I don't know which API to call.
但是我不知道要调用哪个API。
