      "value": "A vulnerability in the SNMP implementation of could allow an authenticated, remote attacker to cause a reload of the affected system or to remotely execute code. An attacker could exploit this vulnerability by sending a crafted SNMP packet to the affected device. \r\n\r\n\r\n\r\nThe vulnerability is due to a buffer overflow in the affected code area. The vulnerability affects all versions of SNMP (versions 1, 2c, and 3). The attacker must know the SNMP read only community string (SNMP version 2c or earlier) or the user credentials (SNMPv3). An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or to cause a reload of the affected system.\r\n\r\n\r\n\r\nOnly traffic directed to the affected system can be used to exploit this vulnerability."

      "value": "El subsistema Simple Network Management Protocol (SNMP) de IOS versión 12.0 hasta 12.4 y versión 15.0 hasta 15.6 y IOS XE versión 2.2 hasta 3.17 de Cisco, contiene múltiples vulnerabilidades que podrían permitir a un atacante remoto autenticado ejecutar el código remotamente en un sistema afectado o causar que un sistema afectado se recargué. Un atacante podría explotar estas vulnerabilidades enviando un paquete SNMP creado a un sistema afectado por medio de IPv4 o IPv6. Solo el tráfico dirigido a un sistema afectado puede ser usado para explotar estas vulnerabilidades. Las vulnerabilidades son debido a una condición de desbordamiento del búfer en el subsistema SNMP del software afectado. Las vulnerabilidades afectan a todas las versiones de SNMP: Versiones 1, 2c y 3. Para explotar estas vulnerabilidades por medio de SNMP Versión 2c o anterior, el atacante necesita conocer la cadena community de solo lectura de SNMP para el sistema afectado. Para explotar estas vulnerabilidades por medio de la versión 3 de SNMP, el atacante necesita tener credenciales de usuario para el sistema afectado. Todos los dispositivos que hayan habilitado SNMP y no hayan excluido explícitamente las MIB u OID afectadas deben considerarse vulnerables. Identificación de errores de Cisco: CSCve66540."
