Descriptions

A vulnerability in Extensible Authentication Protocol (EAP) ingress frame processing for the Cisco Aironet 1560, 2800, and 3800 Series Access Points could allow an unauthenticated, Layer 2 radio frequency (RF) adjacent attacker to cause the Access Point (AP) to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of the EAP frame. An attacker could exploit this vulnerability by sending a malformed EAP frame to the targeted device. A successful exploit could allow the attacker to cause the AP to reload, resulting in a DoS condition while the AP is reloading. It may be necessary to manually power cycle the device in order for it to recover. This vulnerability affects the following Cisco products running either the Lightweight AP Software or Mobility Express image: Aironet 1560 Series Access Points, Aironet 2800 Series Access Points, Aironet 3800 Series Access Points. Note: The Cisco Aironet 1560 Series Access Point device is supported as of release 8.3.112.0. Cisco Bug IDs: CSCve18935.

Una vulnerabilidad en el procesamiento de tramas del puerto entrante de EAP (Extensible Authentication Protocol) para Cisco Aironet 1560, 2800 y 3800 Series Access Points podría permitir que un atacante adyacente sin autenticar en la frecuencia de radio de Capa 2 provoque que el punto de acceso se reinicie, resultando en una denegación de servicio (DoS). Esta vulnerabilidad se debe a la validación insuficiente de tramas EAP. Un atacante podría explotar esta vulnerabilidad enviando una trama EAP mal formada al dispositivo objetivo. Si se explota con éxito, podría permitir que el atacante consiga que el punto de acceso se reinicie, provocando una denegación de servicio cuando se reinicie el punto de acceso. Puede que sea necesario desconectar el dispositivo de la corriente y después volver a conectarlo para que se recupere. Esta vulnerabilidad afecta a los siguientes productos de Cisco que ejecuten la imagen Lightweight AP Software o Mobility Express: Aironet 1560 Series Access Points, Aironet 2800 Series Access Points y Aironet 3800 Series Access Points. Nota: El dispositivo Cisco Aironet 1560 Series Access Point cuenta con soporte para la versión 8.3.112.0. Cisco Bug IDs: CSCve18935.
