Description
An elevation of privilege vulnerability exists when the Windows Diagnostics Hub Standard Collector Service fails to properly sanitize input, leading to an unsecure library-loading behavior. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application.
The security update addresses the vulnerability by correcting how the Windows Diagnostics Hub Standard Collector Service sanitizes input, to help preclude unintended elevated system privileges.
