Goal: Retrieve the file http://localhost:3000/encryptionkey.txt (or similar secret content).
GET /api/Image?url=http://169.254.169.254/latest/meta-data/
In a real-world scenario, this behavior allows attackers to: owasp juice shop ssrf
const ALLOWED_HOSTS = ['images.trusted.com', 'cdn.example.com']; const urlObj = new URL(userUrl); if (!ALLOWED_HOSTS.includes(urlObj.hostname)) return res.status(403).send('Host not allowed');
The vulnerability is often triggered via the Basket or Address endpoints where the server attempts to process a URL. A common vector in Juice Shop involves the callback_url or similar parameter during checkout or order processing, but specifically, Juice Shop uses a parameter named ImageUrl when adding items or editing them, or manipulating the API calls related to product data.
