Geeklog Shoutbox Plugin contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate input upon submission to the Shoutbox script. This could allow a user to send a specially crafted request that would execute arbitrary code on the server leading to a loss of integrity.
Note: The Shoutbox Plugin is not installed during a default Geeklog installation.
