An attacker could exploit this vulnerability by continuously sending SNMP queries to a specific MIB of an affected device. A successful exploit could allow the attacker to cause a kernel panic on the device, resulting in a reload and a DoS condition.\r\nNote: This vulnerability affects SNMP versions 1, 2c, and 3. To exploit this vulnerability through SNMPv1 or SNMPv2c, the attacker must have a valid read-only SNMP community string for the affected system. To exploit this vulnerability through SNMPv3, the attacker must have valid SNMP user credentials for the affected system."},{"lang":"es","value":"Una vulnerabilidad en el subsistema del Protocolo Simple de Gestión de Red (SNMP) de los switches de tejido Cisco Nexus serie 9000 en modo ACI podría permitir a un atacante remoto autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado.\n\nEsta vulnerabilidad se debe a un procesamiento incorrecto al analizar solicitudes SNMP. Un atacante podría explotar esta vulnerabilidad enviando continuamente consultas SNMP a una MIB específica de un dispositivo afectado. Un exploit exitoso podría permitir al atacante causar un pánico del kernel en el dispositivo, lo que resultaría en una recarga y una condición de DoS.\nNota: Esta vulnerabilidad afecta las versiones 1, 2c y 3 de SNMP. Para explotar esta vulnerabilidad a través de SNMPv1 o SNMPv2c, el atacante debe tener una cadena de comunidad SNMP de solo lectura válida para el sistema afectado.
