Last Modified

Products (1)

  • Cisco Nexus 7000 Series Switches

Known Affected Releases

7.0(0)ZD(0.99)

Description (partial)

Symptom:
Cisco Nexus devices enable the SNMP interface by default.  This is a violation of the Cisco Product Security Baseline, non-critical protocols and ports 
should be disabled by default and require explicit configuration before listening on a network interface.

Currently on the switch there will be admin user configured which is mandate while booting the system image. And when there is a user configured on the switch then SecurityD will push that user to snmp. Once we have a user in our snmp userList, users can poll snmp with that username and passwd(snmpv3).

Conditions:
Devices running an affected version of Cisco NX-OS Software

So currently if we disable the snmp port bind then there being a admin usera aslo no body can poll snmp. So that becomes a problem.
