Vulnerability discussion

Whether active or not, default SNMP passwords, users, and passphrases must be changed to maintain security. If the service is running with the default authenticators, then anyone can gather data about the system and the network and use the information to potentially compromise the integrity of the system or network(s).

Check content

Check the SNMP configuration for default passwords. Locate and examine the SNMP configuration. Procedure: # more /etc/sma/snmp/snmpd.conf /var/sma_snmp/snmpd.conf /etc/snmp/conf/snmpd.conf /usr/sfw/lib/sma_snmp/snmpd.conf Identify any community names or user password configuration. If any community name or password is set to a default value, such as public, private, snmp-trap, password, or any value which does not meet DISA password requirements, this is a finding.

Fix text

Change the default passwords. To change them, locate the snmpd.conf file and edit it. Locate the line system-group-read-community which has a default password of public and make the password something more random (less guessable). Make the same changes for the lines that read system-group-write-community, read-community, write-community, trap, and trap-community. Read the information in the file carefully. The trap is defining who to send traps to, for instance, by default. It is not a password, but the name of a host.

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.
