In plain English
A medium-severity cross-site request forgery in Cisco IP Phones with Multiplatform Firmware from Cisco. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 26% of all known vulnerabilities).
Official 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 management 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 a factory reset of the affected device, resulting in a Denial of Service (DoS) condition.
