A vulnerability in the web-based management interface of Cisco AppDynamics Controller could allow an authenticated, remote attacker to perform a reflected cross-site scripting (XSS) attack against a user of the interface of an affected device. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface.
