@alwayscurious @BleepingComputer, even with an unpatched ESXi, having a webserver hosted on a VM exposed to the internet should be fine. Exposing unnecessary services to the internet, like the SLP protocol used by ESXi, or historically problematic services like RDP, is another matter. If you need remote access, at a minimum, put them behind a VPN. Reduce your risk by limiting what is publicly accessible.
