Description
A security feature bypass vulnerability exists in Microsoft Windows when the Task Scheduler service fails to properly verify client connections over RPC. An attacker who successfully exploited this vulnerability could run arbitrary code as an administrator. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, a man-in-the-middle attacker would need to send a specially crafted request to a vulnerable system.
The security update addresses the vulnerability by correcting how the Task Scheduler service validates connections.
