Local privilege escalation via uncontrolled search path
Published Aug 17, 2023 · Updated Oct 8, 2024
Uncontrolled search path handling in Lenovo Universal Device Client before 23.10 allows local users to execute code with elevated privileges. Lenovo identifies the flaw as an uncontrolled search path element but does not disclose the affected executable, loaded object, or searched directory. Low-privileged local access is required; successful exploitation runs attacker-controlled code with the service's elevated privileges.
