Local privilege escalation via writable update script

Published Jun 5, 2023 · Updated Jan 8, 2025

Local privilege escalation in ThinkPad Hybrid USB-C with USB-A Dock Firmware Update Tool before 1.0.35_v2 allows local users to execute elevated code. During an update, the privileged Lenovo service executes DriverInstallerScript.bat from a directory that local users can modify. Exploitation requires local low-privileged access and the affected dock, and successful exploitation grants administrative control over the host.
