Header Reflection in Invalid URLs

Header Reflection in Invalid URLs

Adds a random header to a request for a non-existent page and checks if it is reflected in the response.

Security Misconfiguration (SM)

"By adding a random header to a request for a non-existent page, we check if the response is reflecting all headers, including http-only cookies. If (when) an XSS is found on the domain, this page can be used to fetch all cookies for an administrator and take over their session on the site."

How this template works

APIs Selection

The API selection filters in this template specify the criteria for selecting the API requests to be executed. It filters the requests based on the response code (between 200 and 299), extracts the URL into a variable, checks if the response payload contains the HTML doctype, and ensures that the method is GET.

Execute request

The execute section of the template defines the type of execution as "single" and includes a list of requests to be executed. In this case, there is only one request defined. It adds a custom header to the request, modifies the URL by appending a slash and then replacing any trailing slashes with '/random-url'.

Validation

The validation section specifies the criteria for validating the response of the executed request. In this template, it checks if the response payload contains the string "akto'". If the response payload contains this string, the validation is considered successful.
