# What is Remote Code Execution?

> Remote Code Execution

It is a critical vulnerability that allows an attacker to run his own code on a remote computer.

## Overview

This occurs as a result of an open software not sufficiently checking external commands. An attacker can use this loophole to take control of the computer or steal data. It is one of the most feared security vulnerabilities in the software world.

***Analogy:** It's like giving permission to move all the items in the house with a note under the door, instead of keeping your house key locked.*

## How it works

Systems should never directly run external data and should always undergo strict security auditing.

## Where it is used

It occurs in servers, web applications, and operating system level software.

## Commonly confused with

It grants permission to directly execute code, as opposed to simply reading a file or unauthorized access.

## Questions and answers

**Why is RCE so dangerous?**

Because it allows the attacker to do whatever he wants on your computer.

**How can I prevent this?**

You can prevent it by keeping your software up to date and verifying every data entering the system.
