An authenticated administrator on a node with an optional, separately licensed gateway role enabled could supply a connector URL that the server retrieved without sufficient validation of its scheme or destination, causing the server to issue requests to internal network services. Exploitation requires the licensed gateway role to be active.
Weakness
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.
