What it is

⚠️ A long GET request is all it takes to trigger a buffer overflow in Cmail 2.4.7! This sneaky vulnerability lets attackers execute arbitrary commands on your server. 🔥 Think of it as a crowded restaurant where one customer's overly long order completely overwhelms the kitchen, causing chaos while they try to fulfill it. With Cmail, that chaos means attackers could commandeer your server and run their own orders instead! If exploited, an attacker could take full control of your server, leading to data breaches or malicious activities that can devastate your operations. Imagine unwanted guests throwing a wild party in your space while you’re none the wiser!
