Local privilege escalation via unsafe file operations
Published Mar 12, 2020 · Updated Aug 4, 2024
Improper privilege management in Microsoft Windows allows local users to run elevated processes via a crafted application. The Windows Language Pack Installer mishandles file operations while processing attacker-controlled files, enabling execution in an elevated context. Exploitation requires unprivileged local execution; the documented consequence is privilege elevation with no network attack path.
