## What it is
OWASP Mutillidae II is a deliberately vulnerable PHP web application used as a target for web-security training and practice. It includes over 40 vulnerabilities covering the OWASP Top Ten and is designed for labs, classrooms, CTFs, and testing vulnerability assessment tools.

## Use cases
- practice web application penetration testing
- learn about OWASP Top 10 vulnerabilities hands-on
- set up a hacking lab for security training
- run a CTF target for web exploitation challenges
- test vulnerability scanners against a known-vulnerable app
- teach web security in a classroom setting

## When to choose
- you need a realistic, intentionally vulnerable web app for security training or practice
- you want coverage of OWASP Top 10 vulnerability classes in one target
- you need an easy-to-deploy lab target via Docker, XAMPP, LAMP, or WAMP

## When to avoid
- you need a secure production web application
- you want a general-purpose PHP framework or CMS
- you cannot host the app in an isolated environment, since it is intentionally insecure

## Facets
- artifact type: application
- maturity: active
- function: security, penetration-testing, http-server
- domain: security, penetration-testing, web-development, education
- platform: windows, self-hosted, php
