PostNuke: The Phoenix Release (0.750)

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.

- --- 1. Sql injection in Download ---

This sql injection is non critical because exploit works only with admin rights (mysql).

The problem is in "modules/Downloads/dl-viewdownload.php".

- --------
if ($show!="") {
$perpage = $show;
} else {
$show=$perpage;
}
...
$result =& $dbconn->SelectLimit($sql,$perpage,$min);
- --------

varible $perpage.

So
http://[HOST]/[DIR]/index.php?name=Downloads&req=viewdownload&cid=1&show=[SQL%20INJECTION]

- --- 2. XSS ---

2.0 http://[HOST]/[DIR]/index.php?module=Comments&req=moderate&moderate=<center><h1>xss

2.1 http://cxib.server/PostNuke-0.760-RC4b/html/user.php?op=edituser&htmltext=<h1>xss

- --- 3. How to fix ---

Download the new version of the script or update.
