SV-83731r1_rule The NSX Distributed Logical Router must be configured so inactive router interfaces are disabled.

Vulnerability discussion

An inactive interface is rarely monitored or controlled and may expose a network to an undetected attack on that interface. Unauthorized personnel with access to the communication facility could gain access to a router by connecting to a configured interface that is not in use.

Check content

Verify there are no inactive router interfaces enabled. Log onto vSphere Web Client with credentials authorized for administration. Navigate and select Networking and Security >> "NSX Edges" tab on the left-side menu. Double-click the EdgeID. Click on the "Manage" tab on the top of the new screen, then Settings on the far left >> Interfaces >> Check the "Status" column for the associated interface. If any inactive router interfaces are not disabled, this is a finding.

Fix text

Log onto vSphere Web Client with credentials authorized for administration. Navigate and select Networking and Security >> select the "NSX Edges" tab on the left-side menu. Double-click the EdgeID. Click on the "Manage" tab on the top of the new screen then Settings on the far left >> Interfaces. For interfaces that are not in use, highlight the interface and click the pencil icon. Move the radio button next to "Connectivity Status" to "Disconnected".

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.
