The Consent User Interface (UI) component of the remote Windows host does not properly process a registry key that has been set to a specific value.
An attacker who can log on locally to the affected system and has the ‘Impersonate a client after authentication’ user right (SeImpersonatePrivilege) can exploit this to run arbitrary code with LocalSystem privileges.
