CVE-2023-24930

SYSTEM privilege escalation via improper link resolution

Published Mar 14, 2023 · Updated Feb 28, 2025

Improper link resolution in Microsoft OneDrive for Mac before 23.020.0125.0002 allows local users to gain SYSTEM privileges. The macOS installer follows a filesystem link before accessing its target, allowing an attacker-controlled link to redirect a privileged file operation. Exploitation requires local authentication and low privileges; Microsoft has not published the affected operation or the precise files exposed to replacement.
