Description
A vulnerability in the web-based interface of the Cisco SPA112 2-Port Phone Adapter could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against another user of the device. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the affected device.
