"A vulnerability in the web-based management interface of Cisco IP
Phone 6800, 7800, and 8800 Series with Multiplatform Firmware could
allow an unauthenticated, remote attacker to conduct a cross-site
request forgery (CSRF) attack against a user of the web-based
interface of an affected system. This vulnerability is due to
insufficient CSRF protections for the web-based management interface
of an affected device. An attacker could exploit this vulnerability by
persuading an authenticated user of the interface to follow a crafted
link. A successful exploit could allow the attacker to perform
configuration changes on the affected device, resulting in a denial of
service (DoS) condition.
