DESCRIPTION:
Digitalmunitions.com has reported a vulnerability in Cisco IOS, which
can be exploited by malicious people to conduct script insertion
attacks.

The vulnerability is caused due to missing sanitisation of data
received in CDP (Cisco Discovery Protocol) packets before displaying

arbitrary HTML and JavaScript code in an Administrator's browser
session in the context of the web administration interface when the
status page is viewed.

The vulnerability has been reported in IOS 11.2(8.11)SA6. Other
network devices running IOS 11 with the web administration server
package installed may also be affected.

Alternatively, disable CDP functionality if it is not required, or
disable the web administration interface.
