SNMP community string to exploit this vulnerability.
Note: Only traffic directed to the affected system can be used to exploit this vulnerability.
This vulnerability affects systems configured in routed and transparent firewall mode only and in
single or multiple context mode. This vulnerability can be triggered by IPv4 traffic only. The
attacker requires knowledge of the configured SNMP community string in SNMP version 1 and SNMP
version 2c or a valid username and password for SNMP version 3.");
