Port scanning with SSRF

Port scanning with SSRF

The endpoint appears to be vulnerable to Server Side Request Forgery attack. The original request was replayed by replacing the URI parameter with some of the popular ports. The application responded with 2XX success code indicating that the port is open.

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 some of the popular ports. The application responded with 2XX success code indicating that the port is open. 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 API selection filters in this template are used to filter requests based on specific criteria. In this case, the filters are checking if the request payload or query parameter contains the string "http". If the condition is met, the request will be selected for further processing.

Execute request

The execute section of the template specifies the actions to be performed on the selected requests. In this case, the template modifies the query parameter and body parameter of the selected requests by replacing the "url_key" with the values specified in the "filePaths" word list.

Validation

The validation section defines the criteria for validating the response of the executed requests. It checks if the response code is between 200 and 299 (indicating a successful response) and if the response payload matches any of the provided regular expressions. If the validation criteria are met, the request is considered successful.
