What it is

⚡ A long EXPN command is all it takes to unleash chaos! With MERCUR SMTP server 3.30, attackers could send a crafted request to execute arbitrary commands remotely. 🚨 Think of it like a restaurant where a customer simply requests a very complex order that the chef can't handle—suddenly, the kitchen is flooded with chaos and every dish goes wrong! This buffer overflow could lead to an attacker running any command they please on the server, potentially compromising the entire system. Imagine unauthorized access to confidential data or complete control over the email server—yikes!

Put simply
