Cisco Wireless LAN Controller (WLC) devices with software 4.x, 5.x, 6.0, and 7.0 before 7.0.220.4, when CPU-based ACLs are enabled, allow remote attackers to read or modify the configuration via unspecified vectors, aka Bug ID CSCtu56709.
A vulnerability in the 802.11 Generic Advertisement Service (GAS) frame processing function of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS). The vulnerability is due to incomplete input validation of the 802.11 GAS frames that are processed by an affected device. An attacker could exploit this vulnerability by sending a crafted 802.11 GAS frame over the air to an access point (AP), and that frame would then be relayed to the affected WLC. Also, an attacker with Layer 3 connectivity to the WLC could exploit this vulnerability by sending a malicious 802.11 GAS payload in a Control and Provisioning of Wireless Access Points (CAPWAP) packet to the device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS.
A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol handler of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient validation of CAPWAP packets. An attacker could exploit this vulnerability by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to restart, resulting in a DoS condition.
Cisco Wireless LAN Controller (WLC) devices with software 6.0 and 7.0 before 7.0.220.0, 7.1 before 7.1.91.0, and 7.2 before 7.2.103.0 allow remote attackers to cause a denial of service (device reload) via a sequence of IPv6 packets, aka Bug ID CSCtt07949.
Cisco Wireless LAN Controller (WLC) devices with software 4.x, 5.x, 6.0, and 7.0 before 7.0.220.0 and 7.1 before 7.1.91.0, when WebAuth is enabled, allow remote attackers to cause a denial of service (device reload) via a sequence of (1) HTTP or (2) HTTPS packets, aka Bug ID CSCtt47435.
The administrative management interface on Cisco Wireless LAN Controller (WLC) devices with software 4.x, 5.x, 6.0, and 7.0 before 7.0.220.0, 7.1 before 7.1.91.0, and 7.2 before 7.2.103.0 allows remote attackers to cause a denial of service (device crash) via a malformed URL in an HTTP request, aka Bug ID CSCts81997.
Cisco Unified Wireless Network (UWN) Solution 7.x before 7.0.98.0 on 5508 series controllers allows remote attackers to cause a denial of service (pbuf exhaustion and device crash) via fragmented traffic, aka Bug ID CSCtd26794.
