Server-Side Request Forgery, SSRF for short, is a vulnerability class that describes the behavior of a server making a request that’s under the attacker’s control. This is a story about how I (re)discovered an exploitation technique and took a bug with fairly limited impact to a 5 digit bounty by bypassing existing mitigations. The attacker can supply or a modify a URL which the code running on the server will read or submit data to, and by carefully selecting the URLs, the attacker may be able to read server configuration such as AWS metadata, connect to internal services like http.
