A vulnerability in the HTTP URL redirect feature of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause a buffer overflow condition on an affected device, resulting in a denial of service (DoS) condition.

The vulnerability is due to improper handling of HTTP traffic by the affected software. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to cause a buffer overflow condition on the device, which could allow the attacker to cause the device to reload, resulting in a DoS condition, or execute arbitrary code on the device.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
