Ewon Cosy+ VPN Vulnerability: When Convenience Meets Catastrophe!
The Ewon Cosy+ makes industrial remote access easy, but unfortunately, it also makes it easy for authenticated attackers to inject and execute OS commands. By uploading a custom OpenVPN configuration, attackers can turn this secure VPN gateway into a command execution playground. Remember, with great power comes great vulnerability!
