A vulnerability in Web Authentication (WebAuth) clients for the Cisco Wireless LAN Controller (WLC) and Aironet Access Points running Cisco IOS Software could allow an unauthenticated, adjacent attacker to bypass authentication and pass traffic. The vulnerability is due to incorrect implementation of authentication for WebAuth clients in a specific configuration. An attacker could exploit this vulnerability by sending traffic to local network resources without having gone through authentication. A successful exploit could allow the attacker to bypass authentication and pass traffic. This affects Cisco Aironet Access Points running Cisco IOS Software and Cisco Wireless LAN Controller (WLC) releases prior to 8.5.110.0 for the following specific WLC configuration only: (1) The Access Point (AP) is configured in FlexConnect Mode with NAT. (2) The WLAN is configured for central switching, meaning the client is being assigned a unique IP address. (3) The AP is configured with a Split Tunnel access control list (ACL) for access to local network resources, meaning the AP is doing the NAT on the connection. (4) The client is using WebAuth. • http://www.securityfocus.com/bid/104087 http://www.securitytracker.com/id/1040814 http://www.securitytracker.com/id/1040815 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180502-aironet-auth • CWE-287: Improper Authentication •

A vulnerability in the 802.11 frame validation functionality of the Cisco Wireless LAN Controller (WLC) could allow an unauthenticated, adjacent attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to incomplete input validation of certain 802.11 management information element frames that an affected device receives from wireless clients. An attacker could exploit this vulnerability by sending a malformed 802.11 management frame to an affected device. A successful exploit could allow the attacker to cause the affected device to reload unexpectedly, resulting in a DoS condition. This vulnerability affects only Cisco Wireless LAN Controllers that are running Cisco Mobility Express Release 8.5.103.0. • http://www.securityfocus.com/bid/104080 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180502-wlc-mfdos • CWE-20: Improper Input Validation •

A vulnerability in the Access Network Query Protocol (ANQP) ingress frame processing functionality of Cisco Wireless LAN Controllers could allow an unauthenticated, Layer 2 RF-adjacent attacker to cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to incomplete input validation of ANQP query frames by the affected device. An attacker could exploit this vulnerability by sending a malformed ANQP query frame to an affected device that is on an RF-adjacent network. A successful exploit could allow the attacker to cause the affected device to restart unexpectedly, resulting in a DoS condition. This vulnerability affects Cisco Wireless LAN Controllers that are running a vulnerable release of Cisco WLC Software and are configured to support Hotspot 2.0. • http://www.securityfocus.com/bid/101650 http://www.securitytracker.com/id/1039724 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171101-wlc4 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

A vulnerability in the implementation of 802.11v Basic Service Set (BSS) Transition Management functionality in Cisco Wireless LAN Controllers could allow an unauthenticated, adjacent attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient input validation of 802.11v BSS Transition Management Response packets that an affected device receives from wireless clients. An attacker could exploit this vulnerability by sending a malformed 802.11v BSS Transition Management Response packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload unexpectedly, resulting in a DoS condition.

A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco Wireless LAN Controllers could allow an authenticated, remote attacker to cause an affected device to restart, resulting in a denial of service (DoS) condition. The vulnerability is due to a memory leak that occurs on an affected device after the device fails to deallocate a buffer that is used when certain MIBs are polled. An attacker who knows the SNMP Version 2 SNMP Read string or has valid SNMP Version 3 credentials for an affected device could repeatedly poll the affected MIB object IDs (OIDs) and consume available memory on the device. When memory is sufficiently depleted on the device, the device will restart, resulting in a DoS condition.
