Discussion

It is possible that a disabled port that is assigned to a user or management VLAN becomes enabled by accident or by an attacker and as a result gains access to that VLAN as a member.

Check Content

Review the HP FlexFabric Switch configurations and examine all access switch ports.  Each access switch port not in use should have membership to an inactive VLAN that is not used for any purpose and is not allowed on any trunk links.

If there are any access switch ports not in use and not in an inactive VLAN, this is a finding.
