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
