I first saw this a few days ago. The port should be firewalled off, yes, but
also they should have it bound to localhost and not a public facing port.

Don’t have time to test this out but thought I’d pass this along ….
My first thought is why anyone would have their ports exposed across the
internet to allow this to happen, if it’s possibly true….
