Detailsinfo

A vulnerability was found in Cisco Wireless LAN Controller 4.0/5.0/6.0/7.0 (Wireless LAN Software). It has been declared as critical. Affected by this vulnerability is an unknown code of the component IGMP Handler. The manipulation with an unknown input leads to a resource management vulnerability. The CWE definition for the vulnerability is CWE-399. As an impact it is known to affect availability. The summary by CVE is:

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 weakness was shared 03/05/2014 with Cisco as cisco-sa-20140305-wlc as confirmed advisory (Website). It is possible to read the advisory at tools.cisco.com. The vendor cooperated in the coordination of the public release. This vulnerability is known as CVE-2014-0704 since 01/02/2014. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available. The advisory points out:

When messages are processed, the IGMP subsystem may perform a memory over-read. When subsequent processing is performed on the extraneous data an error may occur that results in a reload of the device. An attacker could exploit this vulnerability by injecting a malicious IGMP version 3 message onto the network that will be received and processed by an affected WLC. An exploit could allow the attacker to trigger a critical error on the WLC, resulting in a DoS condition while the device restarts.
