A friend reported a similar vulnerability at our company about 2 days ago.
Basically there was a insecure SMTP server that you could use to send emails from anyone (internal) to anyone (internal or external).
Literally every employee/contractor on the company network had access to exploit the vulnerability. All you had to do was know how to use the Send-MailMessage function in powershell or something similar.
We work at a publicly traded company, so you could imagine how bad this could've been.
I have no idea if they're using mailgun though. But I wonder if this is related or merely a coincidence?
Note: I'm being intentionally vague about the details for obvious reasons.
