⚡ An authenticated server can send shell commands straight into OpenVPN, like a sneaky chef adding secret ingredients without you knowing! Think of it like a restaurant where the head chef suddenly decides to swap out all the dish ingredients without consulting the menu first. If the chef can decide what goes in, you might end up with something you didn’t order — or worse, something harmful! This vulnerability could allow an attacker to execute arbitrary commands on the host running OpenVPN. Imagine someone hijacking your entire kitchen operation, altering recipes, and sabotaging your business—this is no mere inconvenience; it's a full-blown disaster for your system security!
