“Remote Code Execution (RCE) occurs when an attacker is able to upload code to your website and execute it.

A bug in a PHP application may accept user input and evaluate it as PHP code. This could, for example, allow an attacker to tell the website to create a new file containing code that grants the attacker full access to your website.

When an attacker sends code to your web application and it is executed, granting the attacker access, they have exploited an RCE vulnerability. This is a very serious vulnerability because it is usually easy to exploit and grants full access to an attacker immediately after being exploited.”
