Описание

A vulnerability in the authentication functionality of Cisco Wireless LAN Controller (WLC) AireOS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient error validation. An attacker could exploit this vulnerability by sending crafted packets to an affected device. A successful exploit could allow the attacker to cause the wireless LAN controller to crash, resulting in a DoS condition. Note: This vulnerability affects only devices that have Federal Information Processing Standards (FIPS) mode enabled.
