Devices that are configured with Snort 2 are not affected by this vulnerability. \r\n\r This vulnerability is due to a logic error when handling embryonic (half-open) TCP connections. An attacker could exploit this vulnerability by sending a crafted traffic pattern through an affected device. A successful exploit could allow unintended traffic to enter the network protected by the affected device."}, {"lang": "es", "value": "Una vulnerabilidad en la interacci\u00f3n entre la funci\u00f3n TCP Intercept y el motor de detecci\u00f3n Snort 3 en el software Cisco Firepower Threat Defense (FTD) podr\u00eda permitir que un atacante remoto no autenticado eluda las pol\u00edticas configuradas en un sistema afectado. Los dispositivos que est\u00e1n configurados con Snort 2 no se ven afectados por esta vulnerabilidad. Esta vulnerabilidad se debe a un error l\u00f3gico al manejar conexiones TCP embrionarias (semiabiertas). Un atacante podr\u00eda explotar esta vulnerabilidad enviando un patr\u00f3n de tr\u00e1fico manipulado a trav\u00e9s de un dispositivo afectado.
