Detailsinfo

A vulnerability classified as problematic was found in Cisco Wireless LAN Controller (Wireless LAN Software) (unknown version). Affected by this vulnerability is an unknown code block of the component WIDS. The manipulation with an unknown input leads to a input validation vulnerability (Disconnect). The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect availability.

The weakness was presented 02/18/2015 by Darren Johnson as CSCus46861 as confirmed security notice (Website). The advisory is shared at tools.cisco.com. The public release was coordinated in cooperation with Cisco. This vulnerability is known as CVE-2015-0622 since 01/07/2015. Access to the local network is required for this attack. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available. The advisory points out:

For a Cisco WLC with a default configuration, the attacker could exploit this vulnerability by sending a large number of crafted packets to an affected WLC. The attack requires an administrator to click the IDS events under Security > Wireless Protection Policies > Signature Events Summary in the WLC admin web interface. When the administrator clicks the IDS events after the attacker sends the crafted packets, the WLC becomes unresponsive and all wireless clients are disconnected.

Applying a patch is able to eliminate this problem.

The vulnerability is also documented in the databases at X-Force (100969), SecurityFocus (BID 72665†), SecurityTracker (ID 1031770†) and Vulnerability Center (SBV-48819†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
