Opened: May 13, 2019

Severity: 3-Major


The validation of SNMPv3 user names is not strict, and allows users of both the GUI and TMSH to enter badly formed user names. When the SNMP daemon reads these user names from the snmpd.conf file, validation rejects the names.


The user names are not accepted by the SNMP daemon when it reads the configuration from the snmpd.conf file.


Poorly formed SNMPv3 user names can be entered into configuration, for example, names with embedded spaces.


Use alphanumeric characters for SNMPv3 user names, and do not include embedded spaces in the names.
