*缺陷概述*
 
jQuery File Tree is a configurable, AJAX file browser plugin for the jQuery
javascript library utilised within the Cloupia application framework.
 
Unauthenticated access to this module allows a remote attacker to browse
the entire file system of the host server, beyond the realm of the web
service itself.
 
Cloupia are aware of this flaw and are releasing a patch to mitigate
access. End users are urged to update immediately by contacting the vendor.
