CVE-2020-16938 is a vulnerability that allows you to get unrestricted file read capabilities on the entire disk as unprivileged user. The bug was originally found and reported by my friend Jonas. His PoC can be found here.
My version of the exploit consists of a bunch of Windows API calls to get the handle directly without using 7zip, the PoC can be found in the poc folder which mirrors the tweet I created a while ago.
In short, this exploit allows you to dump the entire disk. The dump in itself can be opened using 7zip or any other parser that supports NTFS.
