Detailsinfo

A vulnerability was found in Cisco Wireless LAN Controller (Wireless LAN Software) and classified as critical. Affected by this issue is some unknown functionality. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is availability. CVE summarizes:

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.

The bug was discovered 07/24/2007. The weakness was disclosed 07/25/2007 (Website). The advisory is shared for download at vupen.com. This vulnerability is handled as CVE-2007-4011 since 07/25/2007. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k.

Upgrading to version 4.0 eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (35576), SecurityFocus (BID 25043†), OSVDB (36660†), Secunia (SA26161†) and SecurityTracker (ID 1018444†). The entry VDB-38013 is pretty similar. Once again VulDB remains the best source for vulnerability data.
