Synopsis

Description

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.
