      "value": "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. This vulnerability affects the following Cisco products if they are running a vulnerable release of Central Web Authentication with FlexConnect Access Points Software: Aironet 1560 Series Access Points, Aironet 1810 Series OfficeExtend Access Points, Aironet 1810w Series Access Points, Aironet 1815 Series Access Points, Aironet 1830 Series Access Points, Aironet 1850 Series Access Points, Aironet 2800 Series Access Points, Aironet 3800 Series Access Points. Note: Central Web Authentication with FlexConnect Access Points was an unsupported configuration until 8.5.100.0. Cisco Bug IDs: CSCve17756."

      "value": "Una vulnerabilidad en Central Web Authentication (CWA) con FlexConnect Access Points (AP) para los AP Cisco Aironet Series 1560, 1810, 1810w, 1815, 1830, 1850, 2800 y 3800 podría permitir que un atacante adyacente autenticado omita una lista de control de acceso (ACL) configurada de FlexConnect. La vulnerabilidad se debe a que el AP ignora la descarga de ACL del cliente durante la autenticación. Un atacante podría explotar esta vulnerabilidad conectándose al dispositivo objetivo con una configuración vulnerable. Su explotación con éxito podría permitir que el atacante omita una ACL configurada del cliente FlexConnect. Esta vulnerabilidad afecta a los siguientes productos de Cisco que ejecutan una versión vulnerable de Central Web Authentication con software FlexConnect Access Points: Aironet 1560 Series Access Points, Aironet 1810 Series OfficeExtend Access Points, Aironet 1810w Series Access Points, Aironet 1815 Series Access Points, Aironet 1830 Series Access Points, Aironet 1850 Series Access Points, Aironet 2800 Series Access Points y Aironet 3800 Series Access Points. Nota: Central Web Authentication con FlexConnect Access Points era una configuración no soportada hasta la versión 8.5.100.0. Cisco Bug IDs: CSCve17756."
