Warning! Audit Deprecated

Information

If products that use the dvfilter network API are not used, the host should not be configured to send network information to a VM. If the API is enabled, an attacker might attempt to connect a VM to it, thereby potentially providing access to the network of other VMs on the host. If a product uses this API, the host must be verified as being correctly configured.

Solution

From the vSphere client select the host and click 'Configuration >> Advanced Settings >> Net' Set the value of Net.DVFilterBindIpAddress to blank if a dvfilter-based network security appliance is not used or (where used) set the value of Net.DVFilterBindIpAddress to match the dvfilter-based network security appliance.
