What was the issue?
Zoom offered a feature to its customers known as vanity URL, where companies could have created their own custom invitation URL for sharing or could add a dedicated and customized website for this service. But due to this nature and a bug in it, any attacker could have just impersonated an organization’s vanity URL link and would have sent illegitimate invitations which looked authentic to the victims. Such an attack could be used to create a phishing campaign where attackers could impersonate the link redirect the victims to a fake website where they could collect the information entered by the target.
