CVE-2024-33578

Elevated code execution via uncontrolled DLL search

Published Oct 11, 2024 · Updated Oct 11, 2024

Uncontrolled DLL search in Lenovo Leyun before 2.501.25.0 allows local users to execute code with elevated privileges. Lenovo identifies the weakness as an uncontrolled search-path element but does not disclose the executable, DLL name, or directory involved. Low-privilege local access is required, and successful exploitation runs attacker-controlled code with the application's elevated rights.
