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.
The mDNS snooping functionality on Cisco Wireless LAN Controller (WLC) devices with software 7.4.1.54 and earlier does not properly manage buffers, which allows remote authenticated users to cause a denial of service (device reload) via crafted mDNS packets, aka Bug ID CSCue04153.
Cisco 4100 and 4400, Airespace 4000, and Catalyst 6500 and 3750 Wireless LAN Controller (WLC) software 4.1 before 4.1.180.0 allows remote attackers to cause a denial of service (ARP storm) via a broadcast ARP packet that "targets the IP address of a known client context", aka CSCsj50374.
Cisco 4100 and 4400, Airespace 4000, and Catalyst 6500 and 3750 Wireless LAN Controller (WLC) software before 3.2 20070727, 4.0 before 20070727, and 4.1 before 4.1.180.0 allows remote attackers to cause a denial of service (traffic amplification or ARP storm) via a crafted unicast ARP request that (1) has a destination MAC address unknown to the Layer-2 infrastructure, aka CSCsj69233; or (2) occurs during Layer-3 roaming across IP subnets, aka CSCsj70841.
Cisco Wireless LAN Controller (WLC) before 3.2.116.21, and 4.0.x before 4.0.155.0, allows remote attackers on a local network to cause a denial of service (device crash) via malformed Ethernet traffic.
The Network Processing Unit (NPU) in the Cisco Wireless LAN Controller (WLC) before 3.2.171.5, 4.0.x before 4.0.206.0, and 4.1.x allows remote attackers on a local wireless network to cause a denial of service (loss of packet forwarding) via (1) crafted SNAP packets, (2) malformed 802.11 traffic, or (3) packets with certain header length values, aka Bug IDs CSCsg15901 and CSCsh10841.
Cisco Aironet 1000 Series and 1500 Series Lightweight Access Points before 3.2.185.0, and 4.0.x before 4.0.206.0, have a hard-coded password, which allows attackers with physical access to perform arbitrary actions on the device, aka Bug ID CSCsg15192.
