    Right in the Security Advisory

    allow an unauthenticated, local attacker to access an affected system using static credentials.

    Edit: NVM, later it says

    The second is using SSH, which is enabled by default on the management interface of the device.

      That could be any user logged into the CLI. Cisco is famously a network appliance company and they make admin available over the network. Anyone who can get to the LAN/VLAN these appliances are on can exploit this. So not specifically physical access.

        You are right:

        The second is using SSH, which is enabled by default on the management interface of the device. SSH can also be enabled on data interfaces.

        Holy fuck.

        Nothing prevents you from putting this on a LAN that can be accessed from over the internet.

          Even if it’s not directly accessible from the internet on its own, if it’s accessible from an host exposed to the internet then anyone that can compromise a single host can immediately compromise the firewall.

          “It’s only exposed to the outdated wordpress server” is effectively the same as being exposed to the internet.

            Yeah that’s my point. Even if the manufacturer actually limits the IP config on the mgmt interface to be configured as not routable over the internet, it could intentionally be on a subnet accessible by some kind of ssh jump server or bastion host. (Or in your example, maybe unintentionally via the Wordpress server.)
