Local privilege escalation via incorrect directory permissions
Published May 1, 2023 · Updated Jan 30, 2025
Incorrect directory permissions in Lenovo System Update before 5.08.01.0005 allow local users to obtain elevated privileges. Lenovo identifies directory-permission management as the fault but has not disclosed the affected directory or the incorrect operation applied to it. Exploitation requires existing low-privileged local access, no user interaction, and high attack complexity; success grants elevated access to protected system resources.
