A vulnerability in the web framework of the Cisco Wireless LAN Controller (WLC) could allow an authenticated, remote attacker to create a denial of service (DoS) condition.
The vulnerability is due to improper input validation of configuration parameters. An attacker could exploit this vulnerability by sending a crafted HTTP request to the Cisco WLC.
Cisco has confirmed the vulnerability in a security notice; however, software updates are not available.
To exploit this vulnerability, an attacker would need to authenticate to the targeted device in order to send crafted HTTP requests to the vulnerable system. This access requirement decreases the likelihood of a successful exploit.
