The endpoint appears to be vulnerable to Server Side Request Forgery attack. The original request was replayed by replacing the URI parameter with metadata endpoint provided by AWS. The application responded with 2XX success code and also gave out sensitive AWS information in response.

Server Side Request Forgery (SSRF)

How this template works

APIs Selection

The template uses API selection filters to specify the criteria for selecting APIs to test. In this case, the filters are based on the response code, where the code should be between 200 and 204 (inclusive), and the request payload or query parameter should contain the string "http".

Execute request

The template defines a single request to be executed. It modifies the query parameter and body parameter of the request by replacing the URL key with the metadata endpoint provided by AWS (http://169.254.169.254/latest/meta-data/local-ipv4).

Validation

The template specifies the validation criteria for the response. It checks that the response code is between 200 and 299 (inclusive) and that the response payload contains either "ami-id", "ami-launch-index", "ami-manifest-path", "block-device-mapping", or "instance-action". If the validation criteria are met, the SSRF vulnerability is considered to be present.
