The vulnerability is due to the improper processing of certain EAPOL messages that are received during the Wi-Fi handshake process. An attacker could exploit this vulnerability by establishing a man-in-the-middle position between a supplicant and an authenticator and manipulating an EAPOL message exchange to force usage of a WPA-TKIP cipher instead of the more secure AES-CCMP cipher. A successful exploit could allow the attacker to conduct subsequent cryptographic attacks, which could lead to the disclosure of confidential information. Cisco Bug IDs: CSCvj29229."},{"lang":"es","value":"Una vulnerabilidad en la implementación de la funcionalidad Extensible Authentication Protocol over LAN (EAPOL) en Cisco Small Business 100 Series Wireless Access Points y Cisco Small Business 300 Series Wireless Access Points podría permitir que un atacante adyacente sin autenticar fuerce la degradación del algoritmo de cifrado empleado entre el autenticador (punto de acceso) y un suplicante (cliente Wi-Fi). La vulnerabilidad se debe al procesamiento incorrecto de ciertos mensajes EAPOL que se reciben durante el proceso de handshake Wi-Fi. Un atacante podría explotar esta vulnerabilidad estableciendo una posición Man-in-the-Middle (MitM) entre un suplicante y un autenticador y manipulando un intercambio de mensajes EAPOL para forzar el uso de un cifrado WPA-TKIP en lugar del cifrado AES-CCMP, más seguro. Su explotación con éxito podría permitir que el atacante lleve a cabo ataques criptográficos subsecuentes, lo que podría conducir a la divulgación de información confidencial.
