Microsoft Windows SMB Server Mount Point Privilege Escalation

Microsoft Windows SMB Server Mount Point Privilege Escalation
Posted Jan 11, 2018
Authored by James Forshaw, Google Security Research

On Microsoft Windows, the SMB server drivers (srv.sys and srv2.sys) do not check the destination of a NTFS mount point when manually handling a reparse operation leading to being able to locally open an arbitrary device via an SMB client which can result in privilege escalation.
