DESCRIPTION:
Multiple vulnerabilities have been reported in multiple Cisco
Wireless Lan Controllers, which can be exploited by malicious people
to bypass certain security restrictions and cause a DoS (Denial of
Service).

1) An error in the administrative management interface can be
exploited to cause a crash via a specially crafted URL.

2) An error when processing IPv6 packets can be exploited to cause a
reload.

3) An error when processing HTTP or HTTPS packets can be exploited to
cause a reload.

Successful exploitation of this vulnerability requires the controller
to be configured for WebAuth.

4) An error when using CPU based access control lists can be
exploited to view and modify the configuration by connecting to the
device on TCP port 1023.

Please see the vendor's advisory for a list of affected products and
versions.

SOLUTION:
Apply update (please see the vendor's advisory for details).

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
