security issue in lenya 1.4

hi !

if you're running lenya 1.4 in production or in any situation where you 
may have untrusted local users, or trusted users with a weird sense of 
humour and advanced computer skills, you will want to comment out the 
following section from your WEB-INF/cocoon.xconf and restart lenya:

<!--
     <component-instance 
class="org.apache.lenya.cms.ac.usecases.UserPassword" 
logger="lenya.admin" name="admin.changePassword">
       <view menu="true" template="usecases/admin/changePassword.jx">
         <tab group="admin" name="users"/>
       </view>
       <exit usecase="admin.user"/>
     </component-instance>
-->

there appears to be a local privilege escalation and dos exploit.

regards,

jörn

I would suggest let's comment it within trunk and add a TODO/Bug that 
this needs to be protected better
before we enable it again.
