A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) Discovery Request parsing functionality of Cisco Wireless LAN Controllers could allow an unauthenticated, remote 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 fields in CAPWAP Discovery Request packets by the affected device. An attacker could exploit this vulnerability by sending crafted CAPWAP Discovery Request packets to an affected device. A successful exploit could allow the attacker to cause the affected device to restart unexpectedly, resulting in a DoS condition. Cisco Bug IDs: CSCvb95842.
CVE-2017-12275 1 Cisco 2 Wireless Lan Controller, Wireless Lan Controller Software 2025-04-20 6.1 MEDIUM 7.4 HIGH
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. Cisco Bug IDs: CSCvb57803.
CVE-2016-9195 1 Cisco 1 Wireless Lan Controller 2025-04-20 5.0 MEDIUM 5.3 MEDIUM

A vulnerability with IPv6 UDP ingress packet processing in Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause an unexpected reload of the device. The vulnerability is due to incomplete IPv6 UDP header validation. An attacker could exploit this vulnerability by sending a crafted IPv6 UDP packet to a specific port on the targeted device. An exploit could allow the attacker to impact the availability of the device as it could unexpectedly reload. This vulnerability affects Cisco Wireless LAN Controller (WLC) running software version 8.2.121.0 or 8.3.102.0. Cisco Bug IDs: CSCva98592.
CVE-2017-12278 1 Cisco 2 Wireless Lan Controller, Wireless Lan Controller Software 2025-04-20 5.2 MEDIUM 6.3 MEDIUM
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. Cisco Bug IDs: CSCvc71674.
