Vulnerability discussion

There are three different TCP/IP stacks by default available on ESXi now which are Default, Provisioning, and vMotion. To better protect and isolate sensitive network traffic within ESXi admins must configure each of these stacks. Additional custom TCP/IP stacks can be created if desired.

Check content

From the vSphere Web Client select the ESXi Host and go to Manage >> Networking >> TCP/IP configuration. Review the default system TCP/IP stacks and verify they are configured with the appropriate IP address information. If any system TCP/IP stack is configured and not in use by a VMkernel adapter, this is a finding.

Fix text

From the vSphere Web Client select the ESXi Host and go to Manage >> Networking >> TCP/IP configuration >> Select a TCP/IP stack >> Click Edit >> Enter the appropriate site specific IP address information for the particular TCP/IP stack and click OK.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
