The vulnerability CVE-2020-1113

CVE-2020-1113 is a Windows Task Scheduler security feature bypass vulnerability.  The vulnerability allows security features in Microsoft Windows to be bypassed. The vulnerability exists because the Task Scheduler service (task scheduling) does not properly verify client connections via RPC. An attacker who successfully exploited this vulnerability could execute arbitrary code as administrator. An attacker could then install programs, view, modify, or delete data, or create new accounts with full user rights.

Microsoft describes the vulnerability in this document and released security updates for Windows 7 through Windows 10 on May 12, 2020. However, users of Windows 7 SP1 and Windows Server 2008 R2 who do not have an ESU license will no longer receive the security updates that Microsoft has released.
