A security feature bypass vulnerability exists when a Windows Projected Filesystem improperly handles file redirections. An attacker who successfully exploited this vulnerability could delete a targeted file they would not have permissions to.

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.

The security update addresses the vulnerability by correcting how Windows Projected Filesystem handle file redirections.
