CVE-2020-1254 →

📋 Description

An elevation of privilege vulnerability exists when Windows Modules Installer Service improperly handles class object members. A locally authenticated attacker 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 how Windows handles calls to preclude unintended elevation.
