Checking if the device is configured to accept Telnet connections is required for devices running either Cisco IOS or Cisco IOS XE Software.

In order to determine if the device is configured to accept incoming Telnet connections, execute the command show running-config | include ^line vty|transport input from a privileged CLI prompt. The command output may indicate one of multiple possible configurations, such as the following:

    The absence of a transport input configuration line after the line vty configuration line indicates the device is using the default set of protocols for incoming connections through a virtual terminal (VTY). The default set of protocols includes the Telnet protocol; hence, this device will accept Telnet connections on all VTYs. This is a vulnerable configuration.

    Switch#show running-config | include ^line vty|transport input
    line vty 0 4
    line vty 5 15
    Switch#

    The device has been explicitly configured to only accept the Secure Shell (SSH) protocol for incoming connections to a subset of the available VTYs, but VTYs numbered 6 to 15 are still using the default set of protocols. Hence, this device will accept Telnet connections to those VTYs. This is a vulnerable configuration.

    Switch#show running-config | include ^line vty|transport input
    line vty 0 4
     transport input ssh
    line vty 5
     transport input ssh
    line vty 6 15
    Switch#

    All available transport protocols have been enabled for incoming connections to all VTYs. Enabling all protocols also enables the Telnet protocol, and will allow Telnet connections to the device. This is a vulnerable configuration.

    Switch#show running-config | include ^line vty|transport input
    line vty 0 4
     transport input all
    line vty 5 15
     transport input all
    Switch#

    The SSH protocol is the only protocol enabled for incoming connections on all VTYs. No Telnet connections are possible to any VTY on the device while using this configuration. This configuration is not vulnerable.

    Switch#show running-config | include ^line vty|transport input
    line vty 0 4
     transport input ssh
    line vty 5 15
     transport input ssh
    Switch#

    Both the Telnet and the SSH protocols have been explicitly enabled as allowed protocols for incoming connections on all VTYs. Telnet connections to the device will be successful under this configuration. This is a vulnerable configuration.

    Switch#show running-config | include ^line vty|transport input
    line vty 0 4
     transport input telnet ssh
    line vty 5 15
     transport input telnet ssh

So, basically, the announcement is saying, "IT IS 2018! TURN OFF YOUR TELNET *NOW*!!!"
