Description

Operating system commands shouldn't be allowed using a web application that resides on a server. Sometimes, web applications are not as safe as they should be, and let users perform disallowed commands in an unexpected way.

In this lab, you will attempt a command execution attack through the DVWA (Damn Vulnerable Web Application) website to force the web server to execute operating system commands to read and display the contents of files and documents that reside outside of the web server's root hosting directory, and which normally should not be accessible from the web.

Learning Objectives

Upon completion of this lab you will be able to:

  • Manage the security level of a DVWA application in order to set it up to your requirements
  • Perform a Command Execution attack from a DVWA application

Intended Audience

This lab is intended for:

  • Individuals who want to learn how to execute command execution attacks
  • Security engineers who want to understand how to better protect their applications from command execution attacks
  • People who want to know how a command execution attack can be performed

Prerequisites

This lab has no prerequisites.
