An attacker could exploit this vulnerability by sending crafted Modbus traffic through an affected device. A successful exploit could allow the attacker to cause the Snort process to hang, causing traffic inspection to stop.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability."}, {"lang": "es", "value": "Una vulnerabilidad en el preprocesador Modbus del motor de detecci\u00f3n Snort podr\u00eda permitir que un atacante remoto no autenticado provoque una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe a un desbordamiento de enteros durante el procesamiento del tr\u00e1fico Modbus. Un atacante podr\u00eda aprovechar esta vulnerabilidad enviando tr\u00e1fico Modbus manipulado a trav\u00e9s de un dispositivo afectado.
