bcoos and E-xoops are two content-community management
system written in PHP-MySQL.

bcoos and E-xoops contains a flaw that allows a remote
cross site scripting attack.This flaw exists because the
application does not validate 'order_by' & 'direction'
variables upon submission to 'index.php' script in
DevTracker module.This could allow a user to create a
specially crafted URL that would execute arbitrary code
in a user's browser within the trust relationship
between the browser and the server,leading loss ofintegrity
