Description Preview

A vulnerability exists 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. This vulnerability could be exploited by an unauthenticated, adjacent attacker to manipulate EAPOL messages during the Wi-Fi handshake process, leading to the downgrade of the encryption algorithm between the access point and Wi-Fi client. By forcing the usage of a less secure WPA-TKIP cipher instead of the more secure AES-CCMP cipher, the attacker could conduct subsequent cryptographic attacks, potentially resulting in the disclosure of confidential information.

Overview

This vulnerability affects Cisco Small Business 100 Series and 300 Series Wireless Access Points, allowing an unauthenticated attacker to downgrade the encryption algorithm used in the Wi-Fi handshake process, potentially leading to the disclosure of confidential information.

Remediation

To mitigate this vulnerability, Cisco has released patches and updates to address the issue. Users of affected devices should apply the necessary updates as soon as possible to ensure the security of their wireless networks. Additionally, network administrators are advised to monitor for any suspicious activity that may indicate exploitation of this vulnerability.
