According to its self-reported version and configuration, the Cisco IOS software running on the remote device is affected by multiple remote code execution vulnerabilities in the Simple Network Management Protocol (SNMP) subsystem due to multiple buffer overflow conditions.
An unauthenticated, remote attacker can exploit these vulnerabilities, via a specially crafted SNMP packet, to execute arbitrary code.

To exploit these vulnerabilities via SNMP version 2c or earlier, the attacker must know the SNMP read-only community string for the affected system. To exploit these vulnerabilities via SNMP version 3, the attacker must have user credentials for the affected system.
