Summary

A vulnerability in the Operations, Administration, Maintenance, and

To determine which release of Cisco Unified CVP software is running, 
administrators can use a web browser to connect to the Cisco Unified CVP 
client via HTTPS. The release number appears on the software home page. The 
following is an example of the text that may appear on the home page:

Products Confirmed Not Vulnerable

No other Cisco products are currently known to be affected by this 
vulnerability.

Workarounds

There are no workarounds that address this vulnerability.

Fixed Software

Cisco has released free software updates that address the vulnerability 
described in this advisory. Customers may only install and expect support for
software versions and feature sets for which they have purchased a license. By
installing, downloading, accessing, or otherwise using such software upgrades,
customers agree to follow the terms of the Cisco software license: 
http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html

Additionally, customers may only download software for which they have a valid
license, procured from Cisco directly, or through a Cisco authorized reseller
or partner. In most cases this will be a maintenance upgrade to software that
was previously purchased. Free security software updates do not entitle 
customers to a new software license, additional software feature sets, or 
major revision upgrades.

When considering software upgrades, customers are advised to regularly consult
the advisories for Cisco products, which are available from the Cisco Security
Advisories and Alerts page, to determine exposure and a complete upgrade 
solution.

In all cases, customers should ensure that the devices to be upgraded contain
sufficient memory and confirm that current hardware and software 
configurations will continue to be supported properly by the new release. If 
the information is not clear, customers are advised to contact the Cisco 
Technical Assistance Center (TAC) or their contracted maintenance providers.

Customers Without Service Contracts

Customers who purchase directly from Cisco but do not hold a Cisco service 
contract and customers who make purchases through third-party vendors but are
unsuccessful in obtaining fixed software through their point of sale should 
obtain upgrades by contacting the Cisco TAC: 
http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html

Customers should have the product serial number available and be prepared to 
provide the URL of this advisory as evidence of entitlement to a free upgrade.

Fixed Releases

This vulnerability is fixed in Cisco Unified Customer Voice Portal software 
release 11.6 or later. The software can be downloaded from the Software Center
on Cisco.com by navigating to Downloads Home > Products > Customer 
Collaboration > Options for Contact Center Solutions > Unified Customer Voice
Portal.

Note: There are Engineering Specials (ES) available for release trains 10.5, 
11.0, and 11.5. Please contact the Cisco TAC for these ES releases which are 
not available from the Software Center on Cisco.com, or download the releases
from the following locations.
