Vulnerable Laravel App

This application was used in my Laracon EU 2019 Amsterdam presentation to demonstrate the following vulnerabilities that are usually caused by poor development practises or mistakes in your code.

This application contains critical security vulnerabilities, DO NOT deploy or run this application outside of your localhost (or expose your localhost while running this)

Requirements

• Docker
• Docker Compose
• PHP (>v7.1 preferably) & Composer

Installation

• composer install
• docker-compose up -d
• docker exec laracon-app php artisan migrate --seed

Vulnerabilities & tips

SQL Injection

• There's a vulnerable API endpoint at http://localhost:1234/api/events?sort=id (assuming you're running this in docker)
• There are many ways to exploit this, if you attended the talk you'll know one very specific tool for this

Object Injection

• The tool used in the presentation is PHPGGC (https://github.com/ambionics/phpggc)
• API endpoints used can be found at /api/uploads & /api/file-details?fileName=xxx

Privilege Escalation

• This project's docker compose setup intentionally configures Laravel scheduler to run as root, that's all you need to know ;)
