Summary
o A vulnerability in the software upgrade process of Cisco TelePresence
Collaboration Endpoint Software and Cisco RoomOS Software could allow an
authenticated, remote attacker to modify the filesystem to cause a denial

The vulnerability is due to insufficient input validation. An attacker with
administrative privileges could exploit this vulnerability by sending
requests with malformed parameters to the system using the console, Secure
Shell (SSH), or web API. A successful exploit could allow the attacker to
modify the device configuration or cause a DoS.

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.
