Cisco Security Notice
Cisco Aironet 3600 Series Access Point Denial of Service Vulnerability
http://tools.cisco.com/security/center/content/CiscoSecurityNotice/CVE-2013-3441
CVE ID: CVE-2013-3441
Release Date: 2013 July 22 14:23 UTC (GMT)
Last Updated: 2013 July 22 14:23 UTC (GMT)
Summary
A vulnerability in the Cisco Aironet 3600 Series Access Point could allow an
unauthenticated, remote attacker to trigger a denial of service condition.
The vulnerability is due to a memory corruption condition that could occur
when the device switches between FlexConnect and Standalone mode. An attacker
could exploit this vulnerability by disrupting the communications path between
a configured and provisioned FlexConnect access point and the Cisco Wireless
LAN Controller. An exploit could allow the attacker to cause the access point
to crash, resulting in a denial of service condition forcing the device to
restart.
This issue has been observed to occur when a switch between FlexConnect and
Standalone mode transpires frequently during a 24 to 48 hour period.
