Vulnerability discussion

Only authorized personnel should be aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state. Additionally, sensitive account information must not be revealed through error messages to unauthorized personnel or their designated representatives.

Check content

Determine if the network device is configured to reveal error messages only to authorized individuals. This requirement may be verified by demonstration or configuration review. This requirement can be met by a central audit server if the network device is configured to send audit logs to that audit server. If the network device reveals error messages to any unauthorized individuals, this is a finding. This is a function of SNMP Traps. Verify the SNMP configuration is present in the output of the "show running-config" command and that SNMP is active via the "show snmp" command.

Fix text

Configure the network device or its associated audit server to reveal error messages only to authorized individuals. SNMP is used to fulfill this function. An example SNMP configuration is provided below. To configure SNMP according to site-specific policies and procedures, refer to the Arista Configuration Guide Chapter 37 snmp-server engineID local snmp-server view snmpview system included snmp-server group ROgroup v3 priv read snmpview snmp-server group RWgroup v3 priv write snmpview snmp-server user disa ROgroup v3 snmp-server user disaRW RWgroup v3 snmp-server host 10.1.1.1 version 3 priv disaRW snmp-server host 10.2.2.2 version 3 noauth disaRW snmp-server host 10.3.3.3 version 3 noauth disaRW snmp-server host 127.0.0.1 version 3 noauth auth snmp-server host 172.22.29.82 version 3 noauth disaRW snmp-server enable traps

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.
