in its web services interface due to improper validation of user-supplied input before returning it to users. An
unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute 
arbitrary script code in a user's browser session.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.
