Vulnerability Information
Windows Diagnostics Hub Elevation of Privilege- CVE-2016-7188
An elevation of privilege vulnerability exists in the Windows Diagnostics Hub Standard Collector Service when the Windows Diagnostics Hub Standard Collector Service fails to properly sanitize input that could lead to unsecure library loading behavior.
To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. 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. The update addresses the vulnerability by correcting an input sanitization error to preclude unintended elevation of privilege.
