Description
An elevation of privilege vulnerability exists in Windows Setup in the way it handles permissions. A locally authenticated attacker could run arbitrary code with elevated system privileges. After successfully exploiting the vulnerability, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by ensuring Windows Setup properly handles permissions.
