      "value": "A vulnerability in the MACsec Key Agreement (MKA) using Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) functionality of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to bypass authentication and pass traffic through a Layer 3 interface of an affected device. The vulnerability is due to a logic error in the affected software. An attacker could exploit this vulnerability by connecting to and passing traffic through a Layer 3 interface of an affected device, if the interface is configured for MACsec MKA using EAP-TLS and is running in access-session closed mode. A successful exploit could allow the attacker to bypass 802.1x network access controls and gain access to the network."

La vulnerabilidad se debe a un error de l\u00f3gica en el software afectado. Un atacante podr\u00eda explotar esta vulnerabilidad conect\u00e1ndose y pasando tr\u00e1fico mediante una interfaz Layer 3 de un dispositivo afectado, si dicha interfaz est\u00e1 configurada para MKA MACsec utilizando EAP-TLS y se est\u00e1 ejecutando en modo \"access-session closed\". Su explotaci\u00f3n con \u00e9xito podr\u00eda permitir que el atacante omita los controles de acceso de red 802.1x y obtenga acceso a la red."
