Description

An elevation of privilege vulnerability exists when Windows CloudStore improperly handles file Discretionary Access Control List (DACL). An attacker who successfully exploited this vulnerability could overwrite a targeted file leading to an elevated status. 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 take control of an affected system. The security update addresses the vulnerability by correcting how Windows CloudStore handles DACLs.
