Lab: SSRF via flawed request parsing


This lab is vulnerable to routing-based SSRF due to its flawed parsing of the request's intended host. You can exploit this to access an insecure intranet admin panel located at an internal IP address.

To solve the lab, access the internal admin panel located in the range, then delete Carlos.


To prevent the Academy platform being used to attack third parties, our firewall blocks interactions between the labs and arbitrary external systems. To solve the lab, you must use Burp Collaborator's default public server (burpcollaborator.net).
