Vulnerability discussion

Network devices with no password for administrative access via a management connection provide the opportunity for anyone with network access to the device to make configuration changes enabling them to disrupt network operations resulting in a network outage.

Review the network device configuration to verify all management connections for administrative access require authentication. With the exception of root, all user access privileges to a Juniper router are defined in a class. All users who log in to the router must be in a login class. Hence, user access to the router is via login class. Following is an example: [edit system] authentication-order [ radius password ]; radius-server { 192.168.6.5 { secret "xxxxxxx"; } } login { /* login classes */ class tier1 { idle-timeout 10; permissions all; } class tier2 { idle-timeout 10; permissions [ configure interface network routing snmp system trace view firewall ]; } /* local emgergency account */ user admin { full-name Administrator; uid 2000; class tier1; authentication { encrypted-password "xxxx"; # SECRET-DATA } } /* RADIUS templates */ user tier1 { uid 2001; class tier1; } user tier2 { uid 2002; class tier2; } } Note: When SSH is enabled, all users can use this service to access the router---including the root account. Access to the root account via SSH must be disabled via root-login deny command. Following is an example configuration: [edit system] services { ssh { root-login deny;

Configure authentication for all management connections.

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.
