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.

The attacker could obtain privileges that are the same level as an administrative user but it depends on the crafted credentials. Note: This vulnerability exists because of a non-default device configuration that must be present for it to be exploitable. For details about the vulnerable configuration, see the Vulnerable Products section of this advisory.
