An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. 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 security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation.

Ein Angreifer kann diese Schwachstellen in Microsoft Windows Server in den Versionen 2012, 2012 R2, 2016, 2019 und 2022, sowie in Microsoft Windows in den Versionen 10 und 11, im Microsoft Windows Admin Center und im Microsoft Configuration Manager ausnutzen, um erweiterte Berechtigungen – einschließlich Administratorrechte – zu erlangen, beliebigen Code auszuführen – sogar mit SYSTEM-Rechten –, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren und offenzulegen, Spoofing-Angriffe durchzuführen und einen Denial-of-Service-Zustand auszulösen.
