Windows Security Feature Bypass Vulnerability
A security feature bypass vulnerability exists in Windows which could allow an attacker to bypass Device Guard. An attacker who successfully exploited this vulnerability could circumvent a User Mode Code Integrity (UMCI) policy on the machine.
To exploit the vulnerability, an attacker would first have to access the local machine, and then run a malicious program.
The update addresses the vulnerability by correcting how Windows validates User Mode Code Integrity policies.
FAQ
After I installed the updates for this vulnerability, my PowerShell ScheduledJob jobs will no longer run with DeviceGuard or AppLocker. What do I need to do?
Use Windows Task Scheduler or PowerShell ScheduledTasks module as an alternative. For more information, see https://blogs.msdn.microsoft.com/powershell/2017/11/02/powershell-constrained-language-mode/.
