Summary

A vulnerability in Central Web Authentication (CWA) with FlexConnect Access Points (APs) for Cisco Aironet 1560, 1810, 1810w, 1815, 1830, 1850, 2800, and 3800 Series APs could allow an authenticated, adjacent attacker to bypass a configured FlexConnect access control list (ACL). The vulnerability is due to the AP ignoring the ACL download from the client during authentication. An attacker could exploit this vulnerability by connecting to the targeted device with a vulnerable configuration. A successful exploit could allow the attacker to bypass a configured client FlexConnect ACL.
