An attacker could exploit this vulnerability by polling an affected device from a source address that should have been denied. A successful exploit could allow the attacker to perform SNMP operations from a source that should be denied.\r\nNote: The attacker has no control of the SNMPv3 configuration. To exploit this vulnerability, the attacker must have valid SNMPv3 user credentials.\r\nFor more information, see the section of this advisory."}, {"lang": "es", "value": "Una vulnerabilidad en la implementaci\u00f3n del Protocolo Simple de Administraci\u00f3n de Redes Versi\u00f3n 3 (SNMPv3) de Cisco IOS Software y Cisco IOS XE Software podr\u00eda permitir que un atacante remoto autenticado sondee un dispositivo afectado mediante SNMP, incluso si el dispositivo est\u00e1 configurado para denegar el tr\u00e1fico SNMP de una fuente no autorizada o si el nombre de usuario SNMPv3 se ha eliminado de la configuraci\u00f3n.
