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 ;)
