What this means for your business

  • It affects Vmware Cloud Foundation. It matters if your company, or a supplier that handles your data, runs it.
  • Code showing how to exploit it has been published, but real attacks have not been confirmed.
  • An attacker can use it remotely, over a network, with an administrator login, and without anyone at your company clicking anything.
