Sensitive AWS details exposed via replacing image param due to SSRF
The endpoint appears to be vulnerable to Server Side Request Forgery attack. The original request was replayed by replacing image upload parameter with url that redirects to AWS IMDS endpoint. 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 the APIs to test. In this case, the filters include checking the response code to be between 200 and 204, and checking if the request payload or query parameter contains a ".jpg" extension.
Execute request
The template uses a single request execution type, which means it will execute a single request. The request is modified to replace the "image_key" query parameter and body parameter with a URL that redirects to an AWS IMDS endpoint.
Validation
The template specifies the validation criteria for the response. It checks if the response code is between 200 and 299, indicating a successful request. It also checks if the response payload contains sensitive AWS information such as "ami-id", "ami-launch-index", "ami-manifest-path", "block-device-mapping", or "instance-action".
