An elevation of privilege vulnerability exists when reparse points are created by sandboxed processes allowing sandbox escape. An attacker who successfully exploited the vulnerability could use the sandbox escape to elevate privileges on an affected system. To exploit the vulnerability, an attacker would first have to log on to the system, and then run a specially crafted application to take control over the affected system. The security update addresses the vulnerability by preventing sandboxed processes from creating reparse points targeting inaccessible files.

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.
