Descriptions

A vulnerability in the implementation of Protected Extensible Authentication Protocol (PEAP) functionality for standalone configurations of Cisco Aironet 1800, 2800, and 3800 Series Access Points could allow an unauthenticated, adjacent attacker to bypass authentication and connect to an affected device. The vulnerability exists because the affected device uses an incorrect default configuration setting of fail open when running in standalone mode. An attacker could exploit this vulnerability by attempting to connect to an affected device. A successful exploit could allow the attacker to bypass authentication and connect to the affected device. This vulnerability affects Cisco Aironet 1800, 2800, and 3800 Series Access Points that are running a vulnerable software release and use WLAN configuration settings that include FlexConnect local switching and central authentication with MAC filtering. Cisco Bug IDs: CSCvd46314.

Una vulnerabilidad en la implementación de la funcionalidad Protected Extensible Authentication Protocol (PEAP) para las configuraciones independientes de Cisco Aironet 1800, 2800, and 3800 Series Access Points podría permitir que un atacante adyacente sin autenticar omita la autenticación y se conecte a un dispositivo afectado. La vulnerabilidad existe porque el dispositivo afectado utiliza una configuración por defecto incorrecta en la que se queda abierto después de que falle cuando se ejecuta en modo independiente. Un atacante podría explotar esta vulnerabilidad intentando conectarse a un dispositivo afectado. Un exploit exitoso podría permitir que el atacante omita la autenticación y se conecte al dispositivo afectado. Esta vulnerabilidad afecta a Cisco Aironet 1800, 2800, and 3800 Series Access Points que estén ejecutando una distribución de software vulnerable y utilicen la configuración WLAN que incluye la conmutación local FlexConnect y la autenticación central con filtrado MAC. Cisco Bug IDs: CSCvd46314.
