Sensitive localhost details exposed via replacing URI param redirecting to localhost/admin due to SSRF

Sensitive localhost details exposed via replacing URI param redirecting to localhost/admin due to SSRF

The endpoint appears to be vulnerable to Server Side Request Forgery attack. The original request was replayed by replacing the URI parameter with localhost/admin. The make-127-0-0-1-rr.1u.ms/admin which redirects to localhost/admin.

Server Side Request Forgery (SSRF)

"The endpoint appears to be vulnerable to Server Side Request Forgery attack. The original request was replayed by replacing the URI parameter with localhost/admin. The make-127-0-0-1-rr.1u.ms/admin which redirects to localhost/admin. Modern concepts in application development make SSRF more common and more dangerous. More common - the following concepts encourage developers to access an external resource based on user input: Webhooks, file fetching from URLs, custom SSO, and URL previews. More dangerous - Modern technologies like cloud providers, Kubernetes, and Docker expose management and control channels over HTTP on predictable, well-known paths. Those channels are an easy target for an SSRF attack. It is also more challenging to limit outbound traffic from your application, because of the connected nature of modern applications. The SSRF risk can not always be completely eliminated. While choosing a protection mechanism, it is important to consider the business risks and needs."

How this template works

APIs Selection

The template uses API selection filters to specify the criteria for selecting the APIs to be tested. 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 the string "http".

Execute request

The template uses the execute section to define the actions to be performed during the execution phase. It specifies a single request to be made, where the query parameter and body parameter of the request are modified to replace the URL with "http://make-127-0-0-1-rr.1u.ms/admin".

Validation

The template uses the validation section to define the expected validation criteria for the response. It checks that the response code is between 200 and 299, and that the response payload contains the string "admin".
