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.

What Is a Cisco Security Notice?

The Cisco Product Security Incident Response Team (PSIRT) publishes Cisco Security Notices to inform customers of low- to mid-level severity security issues involving Cisco products.

Customers who wish to upgrade to a software version that includes fixes for these issues should contact their normal support channels. Free software updates will not be provided for issues that are disclosed through a Cisco Security Notice.
