漏洞描述
中文描述:

Cisco Small Business 100 Series Wireless Access Points和Small Business 300 Series Wireless Access Points都是美国思科（Cisco）公司的不同系列的无线接入点产品，它提供高容量的无线局域网和访客接入服务等功能。 Cisco Small Business 100 Series Wireless Access Points和Small Business 300 Series Wireless Access Points中的Extensible Authentication Protocol over LAN (EAPOL)功能的实现存在加密问题漏洞，该漏洞源于在Wi-Fi握手进程中程序没有正确地处理接收到的EAPOL消息。攻击者可通过实施中间人攻击并操纵EAPOL信息的交换利用该漏洞使用户使用WPA-TKIP加密算法，泄露敏感信息。

英文描述:

A vulnerability in the implementation of Extensible Authentication Protocol over LAN (EAPOL) functionality in Cisco Small Business 100 Series Wireless Access Points and Cisco Small Business 300 Series Wireless Access Points could allow an unauthenticated, adjacent attacker to force the downgrade of the encryption algorithm that is used between an authenticator (access point) and a supplicant (Wi-Fi client). 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.
