An information disclosure vulnerability exists when Windows Mobile Device Management (MDM) Diagnostics improperly handles junctions. An attacker who successfully exploited this vulnerability could bypass access restrictions to read files.

To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and access files.

The security update addresses the vulnerability by correcting the how Windows MDM Diagnostics handles files.
