Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU9096
Risk: Low
CVSSv3.1: 5.3 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-12281
CWE-ID:
CWE-287 - Improper Authentication
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to bypass authentication and connect on the target system.
The weakness exists in the implementation of Protected Extensible Authentication Protocol (PEAP) functionality for standalone configurations of Cisco Aironet 1800, 2800, and 3800 Series Access Points due to incorrect default configuration setting of fail open when running in standalone mode. An adjacent attacker can bypass authentication and cause denial of service.
Install update from vendor's website.

EUVDB-ID: #VU9097
Risk: Low
CVSSv3.1: 5.3 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-12273
CWE-ID:
CWE-287 - Improper Authentication
Exploit availability: No
DescriptionThe vulnerability allows a Layer 2 radio frequency (RF) adjacent attacker to bypass authentication and connect on the target system.
The weakness exists in 802.11 association request frame processing for the Cisco Aironet 1560, 2800, and 3800 Series Access Points due to insufficient frame validation of the 802.11 association request. An adjacent attacker can bypass authentication and cause the AP to reload.
Successful exploitation of the vulnerability results in denial of service.
Install update from vendor's website (8.0.152.0, 8.2.164.0, 8.3.132.0, 8.4.100.0).

CVE-ID: CVE-2017-12274
CWE-ID:
CWE-287 - Improper Authentication
Exploit availability: No
DescriptionThe vulnerability allows a Layer 2 radio frequency (RF) adjacent attacker to cause DoS condition on the target system.
The weakness exists in Extensible Authentication Protocol (EAP) ingress frame processing for the Cisco Aironet 1560, 2800, and 3800 Series Access Points due to insufficient validation of the EAP frame. A remote attacker can send a malformed EAP frame and cause the AP to reload.
Successful exploitation of the vulnerability results in denial of service.
