Brute Force against VMware Horizon

In this report, the researcher discovered a VMWare Horizon admin remote access login portal that was publicly accessible and not sufficiently protected against credential stuffing/brute force attacks. No user accounts were breached; all employees are required to use MFA to login through such portals, but out of an abundance of caution the portal is in the process of being decommissioned. We thank the researcher for their efforts in identifying this potential weakness.
