A vulnerability in the CLI of Cisco TelePresence CE and RoomOS Software could allow an authenticated, local attacker to overwrite arbitrary files on the local system of an affected device. This vulnerability is due to improper access controls on files that are in the local file system. An attacker could exploit this vulnerability by placing a symbolic link in a specific location on the local file system of an affected device. A successful exploit could allow the attacker to overwrite arbitrary files on the affected device.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
