Cisco Wireless LAN Controller (WLC) Authentication Bypass
Description

A vulnerability in the authentication functionality of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to bypass authentication controls and log in to the device through the management interface This vulnerability is due to the improper implementation of the password validation algorithm. An attacker could exploit this vulnerability by logging in to an affected device with crafted credentials.
