Vulnerability discussion

Authentication for administrative (privileged level) access to the device is required at all times. An account can be created on the device's local database for use in an emergency, such as when the authentication server is down or connectivity between the device and the authentication server is not operable. This account is also referred to as the account of last resort since the emergency administration account is strictly intended to be used only as a last resort and immediate administrative access is absolutely necessary.The number of emergency administration accounts is restricted to at least one, but no more than operationally required as determined by the ISSO. The emergency administration account logon credentials must be stored in a sealed envelope and kept in a safe.

Check content

Verify that there is one local account configured on the Cisco ISR 4000 Series router. The configuration should look similar to the example below: username privilege 15 password If there is not a local account configured, this is a finding. If there is more than one local account configured, this is a finding.

Fix text

If there is more than one local account, delete the additional account by using the NO form of the username command. If there is no local account, create one using the following username command: privilege 15 password

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.
