## EoP - Privileged File Delete
During an MSI installation, the Windows Installer service maintains a record of every changes in case it needs to be rolled back, to do that it will create:
* a folder at `C:\Config.Msi` containing
* a rollback script (`.rbs`)
* a rollback file (`.rbf`)
To convert a privileged file delete to a local privilege escalation, you need to abuse the Windows Installer service.
* delete the protected `C:\Config.Msi` folder immediately after it's created by the Windows Installer
* recreate the `C:\Config.Msi` folder with weak DACL permissions since ordinary users are allowed to create folders at the root of `C:\`.
* drop malicious `.rbs` and `.rbf` files into it to be executed by the MSI rollback
* then upon rollback, Windows Installer will make arbitrary changes to the system
The easiest way to trigger this chain is using [thezdi/FilesystemEoPs/FolderOrFileDeleteToSystem](https://github.com/thezdi/PoC/tree/master/FilesystemEoPs/FolderOrFileDeleteToSystem).
The exploit contains a .msi file with 2 actions, the first one produces a delay and the second throws an error to make it rollback. This rollback will "restore" a malicious HID.dll in `C:\Program Files\Common Files\microsoft shared\ink\HID.dll`.
Then switch to the secure desktop using `[CTRL]+[ALT]+[DELETE]` and open the On-Screen Keyboard (`osk.exe`).
The `osk.exe` process first looks for the `C:\Program Files\Common Files\microsoft shared\ink\HID.dll` library instead of `C:\Windows\System32\HID.dll`
