CVSS v3.1 |
| 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. |
| A vulnerability in RADIUS Change of Authorization (CoA) request processing in the Cisco Wireless LAN Controller (WLC) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition by disconnecting a single connection. This vulnerability affects Cisco Wireless LAN Controller running software release 8.3.102.0. More Information: CSCvb01835. Known Fixed Releases: 8.4(1.49) 8.3(111.0) 8.3(108.0) 8.3(104.24) 8.3(102.3). |
| 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 mesh code of Cisco Wireless LAN Controller (WLC) software could allow an unauthenticated, remote attacker to impersonate a WLC in a meshed topology. The vulnerability is due to insufficient authentication of the parent access point in a mesh configuration. An attacker could exploit this vulnerability by forcing the target system to disconnect from the correct parent access point and reconnect to a rogue access point owned by the attacker. An exploit could allow the attacker to control the traffic flowing through the impacted access point or take full control of the target system. This vulnerability affects the following products running a vulnerable version of Wireless LAN Controller software and configured for meshed mode: Cisco 8500 Series Wireless Controller, Cisco 5500 Series Wireless Controller, Cisco 2500 Series Wireless Controller, Cisco Flex 7500 Series Wireless Controller, Cisco Virtual Wireless Controller, Wireless Services Module 2 (WiSM2). Note that additional configuration is needed in addition to upgrading to a fixed release. Cisco Bug IDs: CSCuc98992 CSCuu14804. |
| 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 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. |
| Cisco Wireless LAN Controller (WLC) devices allow remote attackers to cause a denial of service (NULL pointer dereference and device restart) via a zero value in Cisco Discovery Protocol packet data that is not properly handled during SNMP polling, aka Bug ID CSCuo12321. |
| 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. |
| Cisco Wireless LAN Controller (WLC) devices with software 7.4(1.1) allow remote attackers to cause a denial of service (wireless-networking outage) via crafted TCP traffic on the local network, aka Bug ID CSCug67104. |
| 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. |
| 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. |
| 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 Adaptive Wireless Intrusion Prevention System (wIPS) feature on Cisco Wireless LAN Controller (WLC) devices before 8.0.140.0, 8.1.x and 8.2.x before 8.2.121.0, and 8.3.x before 8.3.102.0 allows remote attackers to cause a denial of service (device restart) via a malformed wIPS packet, aka Bug ID CSCuz40263. |
| Cisco Wireless LAN Controller (WLC) devices before 8.0.140.0, 8.1.x and 8.2.x before 8.2.121.0, and 8.3.x before 8.3.102.0 allow remote attackers to cause a denial of service (device reload) by sending crafted Inter-Access Point Protocol (IAPP) packets and then sending a traffic stream metrics (TSM) information request over SNMP, aka Bug ID CSCuz40221. |
| 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. |
