This advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20101206-cuvc.
These vulnerabilities affect the following Cisco UVC Linux operating system products:
The following Cisco UVC VxWorks operating system products are affected by a subset of these vulnerabilities. The Details for Reported Vulnerabilities section indicates if products that are based on the Linux operating system, the VxWorks operating system, or both are affected by an individual vulnerability.
All versions of system software prior to the first fixed, which is indicated in the Software Version and Fixes Table, are affected.
To view the version of system software that is currently running on Cisco Unified Videoconferencing 5100 Series Products, access the Cisco UVC device via the web GUI interface. On the status screen, the "Software Version" field below the "Product Information" section indicates the current system software.
To exploit any of these vulnerabilities, a remote user must authenticate to the administrative interface or to the system via FTP, Telnet, or SSH.
No other Cisco products are currently known to be affected by these vulnerabilities.
The following vulnerabilities have been reported against the Cisco UVC devices:
The following security vulnerabilities which were reported against the Cisco UVC devices, have been classified as security best practices or service misconfiguration issues and as such have not been assigned CVE identifiers.
Administrators can mitigate these vulnerabilities by limiting access to Cisco UVC web server to only trusted hosts. This could be achieved by infrastructure access control lists (iACL) on routers or switches that the Cisco UVC is connected to.
To disable FTP, SSH, and Telnet services, change the configuration setting "Security mode" field in the "Security" section of the Cisco UVC web GUI to "Maximum." For further information, consult the Configuration Guide for Cisco Unified Videoconferencing 5000 MCU Release 7.0 at the following link: http://www.cisco.com/en/US/docs/video/cuvc/7_0/configuration_guide/setup.html#wp1690479
When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance.
All Cisco UVC software versions prior to the first fixed software release, which is indicated in the following table, are affected by the associated vulnerabilities.

Note: Once a fixed version of software has been installed on the affected device to active the above fixes the following configuration steps must be undertaken (This process is network disruptive and the device will reload during activation of the advanced security parameters):
Log into the device after upgrading the software and enter the "Advanced Parameters" configuration section of the web GUI. In the "CLI" section of the page enter in the "command" field strongsecuritymode and in the "Parameter" field Enable . The "Value" field remains empty. Click the execute button on the screen. The device will now reload and reconfigure based on the advanced security settings. Once the device reloads, access the device via HTTPS rather than HTTP.
Currently fixed software can be obtained by contacting your maintenance provider. This section will be updated with the links on Cisco.com to download the system software once the software is published to Cisco.com.
The Cisco PSIRT is not aware of any malicious use of the vulnerabilities described in this advisory.
