CVE-2017-12281
HighSummary
A vulnerability in the implementation of PEAP functionality for standalone configurations of Cisco Aironet 1800, 2800, and 3800 Series Access Points could allow an unauthenticated, adjacent attacker to bypass authentication and connect to an affected device. The issue arises from an incorrect default configuration setting that allows fail open in standalone mode.
Risk Assessment
The organization may be exposed to unauthorized access to the network, potentially leading to data theft or other malicious activities. Attackers could gain access to network resources, posing a serious security threat.
Recommendation
It is recommended to update the access points' software to the latest version that addresses this vulnerability. Additionally, WLAN configuration settings should be reviewed and adjusted to prevent unauthorized access.

Original NVD description (English source)
A vulnerability in the implementation of Protected Extensible Authentication Protocol (PEAP) functionality for standalone configurations of Cisco Aironet 1800, 2800, and 3800 Series Access Points could allow an unauthenticated, adjacent attacker to bypass authentication and connect to an affected device. The vulnerability exists because the affected device uses an incorrect default configuration setting of fail open when running in standalone mode. An attacker could exploit this vulnerability by attempting to connect to an affected device. A successful exploit could allow the attacker to bypass authentication and connect to the affected device. This vulnerability affects Cisco Aironet 1800, 2800, and 3800 Series Access Points that are running a vulnerable software release and use WLAN configuration settings that include FlexConnect local switching and central authentication with MAC filtering. Cisco Bug IDs: CSCvd46314.
