DESCRIPTION:
Digitalmunitions.com has reported a vulnerability in Cisco IOS, which

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.
