## Description
On vulnerable versions of Windows the alpc endpoint method SchRpcSetSecurity implemented by the task scheduler service can be used to write arbitrary DACLs to `.job` files located in `c:\windows\tasks` since the scheduler does not use impersonation when checking this location. Since users can create files in the `c:\windows\tasks` folder, a hardlink can be created to a file the user has read access to. After creating a hardlink, the vulnerability can be triggered to set the DACL on the linked file. This module has been tested against Windows 10 Pro x64.
