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.

Security readout for executives and security teams

This is an old Cisco wireless controller flaw that can let a remote attacker trigger excessive ARP traffic and disrupt wireless network availability. The sources describe denial of service, not data theft or system takeover. Exposure is likely limited to legacy Cisco 4100, 4400, Airespace 4000, Catalyst 6500, or Catalyst 3750 WLC deployments running the vulnerable software branches listed in the CVE. Prioritize where legacy Cisco wireless controllers support critical sites, guest access, manufacturing, healthcare, or operations. The main business risk is wireless outage or instability, not compromise of sensitive data. Mitigation focus: Inventory legacy Cisco WLC platforms and software versions.; Compare versions against Cisco advisory 20070724 guidance.; Upgrade vulnerable 3.2, 4.0, or 4.1 WLC software to fixed releases..
