Technical Analysis
CVE-2020-0863 is an arbitrary file read vulnerability. During the course of execution, the Diagnostic Tracking service in Windows reads a set of configuration files from a user-controlled directory, and copies them to a directory readable to everyone. While it is not possible to change the location of the write, using an oplock and file junctions, an attacker can manipulate the source file, causing the service to copy a file from a privileged area to a location readable by everyone.
