Summary
A vulnerability in Web Administrator Interface of Cisco Wireless LAN
Controllers (WLC) could allow an authenticated, remote attacker to cause a
denial of service (DoS) condition..
The vulnerability is due to a failure to properly validate certain parameters
prior to processing them on the device. An authenticated attacker with an
account that is a member of either the Full Manager, Read Only, or Lobby
Ambassador managers group could exploit this vulnerability by submitting a
request to the affected device that contains a missing or malformed value for
specific parameters. An exploit could allow the attacker to crash the device
resulting in a DoS condition during a system reboot.
