## Description

Razer Synapse before 3.7.0228.022817 allows privilege escalation because it relies on %PROGRAMDATA%\Razer\Synapse3\Service\bin even if %PROGRAMDATA%\Razer has been created by any unprivileged user before Synapse is installed. The unprivileged user may have placed Trojan horse DLLs there.
