Advisory ID:. First Published:. Version 1. Base 6. Vulnerable Products At the time of publication, this vulnerability affected Cisco devices if they were running a vulnerable release of Cisco IOS XE Software and had the guest shell feature enabled. Determining the Device Configuration To determine whether the guest shell is enabled on a device, an administrator can use the show app-hosting detail appid guestshell command and check the value of State.

The following example shows the output of show app-hosting detail appid guestshell when the feature is enabled: Switch show app-hosting detail appid guestshell App id : guestshell Owner : iox State : RUNNING.

Refer to What controllers can be used to support guest access in the unsecured network area? A maximum of guest usernames and passwords can be stored on each controller's database. Therefore, if the total number of active guest credentials is in excess of this number, more than one controller will be needed. The number of access points in the network does not impact the selection of the guest anchor controller. The controller can terminate up to 15 EoIP tunnels. More than one guest anchor controller can be configured if additional tunnels are required.

One EoIP tunnel is configured between the guest anchor controller and each internal controller that supports access points with guest client associations. In such cases the remote and anchor controller should run the same version of WLC software. However, the recent software versions do allow the remote and anchor controllers to have different versions.

The guest tunnel anchor function, which includes EoIP tunnel termination, Web authentication, and access control of guest clients, is supported in these Cisco Wireless LAN Controller platforms with Version 4.

On any firewall between the guest anchor controller and the remote controllers, these ports need to be open:. In this scenario, authentication is always done by the anchor WLC. Click on the drop-down box near a WLAN and choose Mobility Anchors which contains the status of control and data path.

The error message is seen due to one of these reasons:. Anchor and internal controllers are on different versions of code. Make sure they run same versions of the code. Misconfigurations in the mobility anchor configuration. This would result in guest users unable to pass the traffic. Else, DHCP request from clients are dropped and you see this error message on the internal controller:.

Use the show dhcp proxy command on both controllers in order to verify that both controllers have the same DHCP proxy setting. Guest traffic is transported within the enterprise at Layer 3 via EoIP. Therefore, the first point at which Dynamic Host Configuration Protocol DHCP services can be implemented is locally on the guest anchor controller, or the guest anchor controller can relay client DHCP requests to an external server. For information on how to customize a web portal, refer to Choosing the Web Authentication Login Page.

In WCS or NCS, the person with a lobby ambassador account is able to create, assign, monitor, and delete guest credentials for the controller serving as a guest anchor controller. The lobby ambassador can enter the guest username or user ID and password, or the credentials can be autogenerated. There is also a global configuration parameter that enables the use of one username and password for all guests, or a unique username and password for each guest.
