Tests for open redirect vulnerability by injecting evil.com into host headers, ensuring secure redirection and protection against malicious redirects.

Security Misconfiguration (SM)

Impact of the vulnerability

This behavior can be leveraged to facilitate phishing attacks against users of the application.

How this template works

APIs Selection

The API selection filters in this template are used to filter the requests based on the response code. In this case, the filter is set to only select requests with a response code equal to 302 (redirect).

Execute request

The execute section of the template specifies the type of execution (single) and the requests to be executed. In this case, the requests include adding various headers with the value "evil.com" to test for open redirect vulnerability. The follow_redirect parameter is set to false to prevent automatic redirection.

Validation

The validation section defines the criteria for validating the response. It checks if the response code is equal to 302 and if the response headers contain the key "location" with a value that contains either "evil.com". This ensures that the response indicates a redirect to a potentially malicious website.
