Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

PostNuke: The Phoenix Release (0.7.2.6)

PostNuke is an open source, open developement content management system
(CMS).  PostNuke started as a fork from PHPNuke (http://www.phpnuke.org) and
provides many enhancements and improvements over the PHP-Nuke system.  PostNuke
is still undergoing development but a large number of core functions are now
stabilising and a complete API for third-party developers is now in place.
If you would like to help develop this software, please visit our homepage
