CVE-2015-8534Public exploit

SYSTEM code execution via writable installer directory

Published Mar 27, 2020 · Updated Aug 6, 2024

Local privilege escalation in Lenovo Solution Center before 3.3.002 allows local users to execute arbitrary code with SYSTEM privileges. LSCTaskService runs as SYSTEM and exposes LSCController.dll methods through a local HTTP daemon; RunInstaller executes code from a per-user writable directory. A standard local account can exploit the writable execution path after Solution Center has been launched and while the backend service is running.
