Cisco Business Wireless Access Points Social Login Guest User Authentication Bypass Vulnerability

A vulnerability in the social login configuration option for the guest users of Cisco Business Wireless Access Points (APs) could allow an unauthenticated, adjacent attacker to bypass social login authentication. This vulnerability is due to a logic error with the social login implementation. An attacker could exploit this vulnerability by attempting to authenticate to an affected device. A successful exploit could allow the attacker to access the Guest Portal without authentication.
