| A vulnerability in 802.11 Wireless Multimedia Extensions (WME) action frame processing in Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. The vulnerability is due to incomplete input validation of the 802.11 WME packet header. An attacker could exploit this vulnerability by sending malformed 802.11 WME frames to a targeted device. A successful exploit could allow the attacker to cause the WLC to reload unexpectedly. The fixed versions are 8.0.140.0, 8.2.130.0, and 8.3.111.0. Cisco Bug IDs: CSCva86353. |
| 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. |
| 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. Cisco Bug IDs: CSCve05779. |
| A vulnerability in the web management interface 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 a missing internal handler for the specific request. An attacker could exploit this vulnerability by accessing a specific hidden URL on the GUI web management interface. A successful exploit could allow the attacker to cause a reload of the device, resulting in a DoS condition. This vulnerability affects only the Cisco Wireless LAN Controller 8.3.102.0 release. Cisco Bug IDs: CSCvb48198. |
| Cisco Wireless LAN Controller (WLC) devices 7.2 before 7.2.115.2, 7.3, and 7.4 before 7.4.110.0 allow remote attackers to cause a denial of service (device restart) via a crafted 802.11 Ethernet frame, aka Bug ID CSCue87929. |
| The RADIUS functionality on Cisco Wireless LAN Controller (WLC) devices with software 7.0(250.0) and 7.0(252.0) allows remote attackers to disconnect arbitrary sessions via crafted Disconnect-Request UDP packets, aka Bug ID CSCuw29419. |
| The Internet Access Point Protocol (IAPP) module on Cisco Wireless LAN Controller (WLC) devices with software 8.1(104.37) allows remote attackers to trigger incorrect traffic forwarding via crafted IPv6 packets, aka Bug ID CSCuv40033. |
| The multicast listener discovery (MLD) service on Cisco Wireless LAN Controller (WLC) devices 7.2, 7.3, 7.4 before 7.4.121.0, and 7.5, when MLDv2 Snooping is enabled, allows remote attackers to cause a denial of service (device restart) via a malformed IPv6 MLDv2 packet, aka Bug ID CSCuh74233. |
| Cisco Wireless LAN Controller (WLC) devices with software 7.0(240.0), 7.3(101.0), and 7.4(1.19) allow remote attackers to cause a denial of service (device outage) by sending malformed 802.11i management data to a managed access point, aka Bug ID CSCub65236. |
| The Web Management GUI on Cisco Wireless LAN Controller (WLC) devices with software 7.4(140.0) and 8.0(120.0) allows remote attackers to cause a denial of service (client disconnection) via unspecified vectors, aka Bug ID CSCuw10610. |
| The IGMP implementation on Cisco Wireless LAN Controller (WLC) devices 4.x, 5.x, 6.x, 7.0 before 7.0.250.0, 7.1, 7.2, and 7.3, when IGMPv3 Snooping is enabled, allows remote attackers to cause a denial of service (memory over-read and device restart) via a crafted field in an IGMPv3 message, aka Bug ID CSCuh33240. |
| Cisco Wireless LAN Controller (WLC) devices with software 7.0(240.0) allow local users to execute arbitrary OS commands in a privileged context via crafted CLI commands, aka Bug ID CSCuj39474. |
| Cisco Wireless LAN Controller (WLC) devices with software 7.5(102.0) and 7.6(1.62) allow remote attackers to cause a denial of service (device crash) by triggering an exception during attempted forwarding of unspecified IPv6 packets to a non-IPv6 device, aka Bug ID CSCuj01046. |
| Cisco Wireless LAN Controller (WLC) devices 7.0 before 7.0.250.0, 7.2, 7.3, and 7.4 before 7.4.110.0 do not properly deallocate memory, which allows remote attackers to cause a denial of service (reboot) by sending WebAuth login requests at a high rate, aka Bug ID CSCuf52361. |
| Cisco Wireless LAN Controller (WLC) devices 7.4 before 7.4.110.0 distribute Aironet IOS software with a race condition in the status of the administrative HTTP server, which allows remote attackers to bypass intended access restrictions by connecting to an Aironet access point on which this server had been disabled ineffectively, aka Bug ID CSCuf66202. |
| The web administration interface on Cisco Wireless LAN Controller (WLC) devices before 7.0.241, 7.1.x through 7.4.x before 7.4.122, and 7.5.x and 7.6.x before 7.6.120 allows remote authenticated users to cause a denial of service (device crash) via unspecified parameters, aka Bug IDs CSCum65159 and CSCum65252. |
| The wireless web-authentication subsystem on Cisco Wireless LAN Controller (WLC) devices 7.5.x and 7.6.x before 7.6.120 allows remote attackers to cause a denial of service (process crash and device restart) via a crafted value, aka Bug ID CSCum03269. |
| Cross-site scripting (XSS) vulnerability in the HTML help system on Cisco Wireless LAN Controller (WLC) devices before 8.0 allows remote attackers to inject arbitrary web script or HTML via a crafted URL, aka Bug ID CSCun95178. |
| The Wireless Intrusion Detection (aka WIDS) functionality on Cisco Wireless LAN Controller (WLC) devices allows remote attackers to cause a denial of service (device outage) via crafted packets that are improperly handled during rendering of the Signature Events Summary page, aka Bug ID CSCus46861. |
| Cisco Wireless LAN Controller (WLC) devices 7.4(121.0) and 8.0(0.30220.385) allow remote attackers to cause a denial of service via crafted wireless management frames, aka Bug ID CSCun92979. |
