How it was found

Summary

A link on https://about.gitlab.com/resellers/ was broken and could've allowed a user to impersonate a reseller and attack / scam your customers.

Proof of Concept

1.) Visit https://about.gitlab.com/resellers/ 2.) Hit Ctrl+F and find "intenso" {F219301} 3.) Now click the Facebook link and you'll see the Facebook page I've "hijacked" (https://www.facebook.com/InTENSO.IT.Enterprise.Solutions)

This happened because this reseller either deleted their Facebook page or changed their username. Not much you could do about that, but I thought I'd report it because it could be used to attack / scam your customers.
