Open redirect subdomain whitelist

Open redirect subdomain whitelist

An attacker can construct a URL within the application that causes a redirection to an arbitrary external domain by leveraging subdomain whitelisting.

Security Misconfiguration (SM)

"Open redirection vulnerabilities arise when an application incorporates user-controllable data into the target of a redirection in an unsafe way. The ability to use an authentic application URL, targeting the correct domain and with a valid SSL certificate (if SSL is used), lends credibility to the phishing attack because many users, even if they verify these features, will not notice the subsequent redirection to a different domain"

How this template works

APIs Selection

The API selection filters in this template are used to filter the responses based on specific criteria. In this case, the filters check for a response code of 302 (redirect) and extract the value of the "location" header from the response.

Execute request

The execute section of the template defines the actions to be performed on the request. It modifies the query parameter, body parameter, and header of the request by replacing the value of the "location" key with a malicious URL constructed using the extracted value from the response. It also disables following redirects.

Validation

The validation section checks the response code and response headers of the modified request. It ensures that the response code is still 302 (redirect) and that the "location" header contains either "evil.com". This validates that the modification was successful and the redirection is happening as intended.
