      "value": "A vulnerability in the access control list (ACL) programming of Cisco IOS Software running on Cisco Industrial Ethernet 4000, 4010, and 5000 Series Switches could allow an unauthenticated, remote attacker to bypass a configured ACL.\r\n\r This vulnerability is due to the incorrect handling of IPv4 ACLs on switched virtual interfaces when an administrator enables and disables Resilient Ethernet Protocol (REP). An attacker could exploit this vulnerability by attempting to send traffic through an affected device. A successful exploit could allow the attacker to bypass an ACL on the affected device."

      "value": "Una vulnerabilidad en la programaci\u00f3n de la lista de control de acceso (ACL) del software Cisco IOS que se ejecuta en los switches Cisco Industrial Ethernet de las series 4000, 4010 y 5000 podr\u00eda permitir que un atacante remoto no autenticado omita una ACL configurada. Esta vulnerabilidad se debe al manejo incorrecto de las ACL de IPv4 en las interfaces virtuales conmutadas cuando un administrador habilita y deshabilita el protocolo Resilient Ethernet (REP). Un atacante podr\u00eda aprovechar esta vulnerabilidad al intentar enviar tr\u00e1fico a trav\u00e9s de un dispositivo afectado. Una explotaci\u00f3n exitosa podr\u00eda permitir al atacante omitir una ACL en el dispositivo afectado."
