This particular vulnerability allows an attacker to excape from the sandbox of the VM guest to potentntially obtain a code-execution level access to the Guest operating system. If there is no blocking mechanism in place, an attack that takes place via this vulnerability would access the host operating system and any subsequent VMs running on this particular host. Successful exploitation of VM vulnerability could potentially expose unauthenticated access to IP or Intellectual Property of the Corporate and additionally reveal personally identifiable and sensitive information that affects the lives of millions of users worldwide. These users are those that make use of VM or use VPS services involving shared computer resources, storage, and connectivity and security services. Technical DescriptionVulnerability DescriptionVENOM stands for Virtualized Environtment Neglected Operation Manipulation and is a zero day flow that takes full advantage of the ‘Virtual Floppy Disk Drive Controller’. This vulnerability potentially allows the attacker to exit the boundaries of the VM environment and spill over to the host operating system including other VMs on that host. Crowdstrike, a renowned security intelligence corporation has discovered this vulnerability and explains thatthe attacker has first to gain root level privileges of the system in order to make use of this vulnerability. This is a major barrier to this particular exploitation, however it is not
