This vulnerability is classified under CWE-345. 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. Affected products include: Cisco Ip Phone 6871 Firmware, Cisco Ip Phone 6861 Firmware, Cisco Ip Phone 6851 Firmware, Cisco Ip Phone 6841 Firmware, Cisco Ip Phone 6825 Firmware.
