Summary

OpenVPN Connect version 3.1.0.361 for Windows contains a vulnerability due to insecure permissions in the directory %PROGRAMDATA%\OpenVPN Connect\drivers\tap\amd64\win10. This misconfiguration allows local users to manipulate the system by placing a malicious 'drvstore.dll' file into the directory, potentially leading to escalated privileges and further exploitation of the system.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
