exteND Director, a set of development tools for creating enterprise
web applications.

The version of this control on the remote host reportedly contains a
method named 'launch()' that can be used to execute arbitrary
commands.  If an attacker can trick a user on the affected host into
visiting a specially crafted web page, these issues could be leveraged
to execute arbitrary code on the host subject to the user's privileges." );
