## Affected

- EfficientLab, LLC Controlio: fixed in 1.3.95

## Description

EfficientLab Controlio before v1.3.95 contains a DLL hijacking vulnerability caused by weak folder permissions in the installation directory. A local attacker can place a specially crafted DLL in this directory and achieve arbitrary code execution with highest privileges, because the affected service runs as NT AUTHORITY\SYSTEM.
