Summary

  • Three critical vulnerabilities have been found in virtual-machine products from VMware that give potential hackers unusually broad access to internal networks.
  • The attack method, known as hyperjacking, hypervisor attack or virtual machine escape, involves breaking out of a customer’s virtual machine (VM) in order to take control of the hypervisor that apportions each VM.
  • From there, an attacker can access the VMs of other customers, environments that are typically used to host internal networks.
  • Security researcher Kevin Beaumont said on Mastodon: “If you can escape to the hypervisor you can access every system.
  • All bets are off as a boundary is broken.”
  • VMware has said it has evidence the vulnerabilities are already being exploited.
