      "value": "A vulnerability in the Simple Network Management Protocol (SNMP) punt handling function of Cisco cBR-8 Converged Broadband Routers could allow an authenticated, remote attacker to overload a device punt path, resulting in a denial of service (DoS) condition. This vulnerability is due to the punt path being overwhelmed by large quantities of SNMP requests. An attacker could exploit this vulnerability by sending a large number of SNMP requests to an affected device. A successful exploit could allow the attacker to overload the device punt path, resulting in a DoS condition."

Esta vulnerabilidad es debido a que la ruta de b\u00fasqueda est\u00e1 sobrecargada por grandes cantidades de peticiones SNMP. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de un gran n\u00famero de peticiones SNMP a un dispositivo afectado.
