Techniques & Countermeasures

  • CWE-441•Unintended Proxy or Intermediary ('Confused Deputy')

    The product receives a request, message, or directive from an upstream component, but the product does not sufficiently preserve the original source of the request before forwarding the request to an external actor that is outside of the product's control sphere. This causes the product to appear to be the source of the request, leading it to act as a proxy or other intermediary between the upstream component and the external actor.

  • CWE-918•Server-Side Request Forgery (SSRF)

    The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
