PHP-FUSION Various Vulnerabilities
------------------------------------------------------------------------
SUMMARY
" <http://sourceforge.net/projects/php-fusion/> PHP-Fusion is an
all-in-one content management system (CMS) written in PHP4. It uses a
MySQL database to store all of it's content such as News, Articles, Forum
Posts, Shoutbox Posts and more."
Multiple varied vulnerabilities were found in PHP-FUSION. The
vulnerabilities range from simple path disclosure to script direct access
and even gaining administrative access.
DETAILS
Vulnerable Systems:
* PHP-FUSION version 4.00
The full path to the CMS can be found because scripts are not protected
against direct access. In such an event, sending an invalid query will
return a standard error from the backend DB server.
* First script is at fusion_admin/updateuser.php.
Example:
http://localhost/fusion/fusion_admin/updateuser.php
The output generated is roughly:
Warning: main(fusion_langdiradmin/admin_members.php): failed to open
stream:
No such file or directory in
/var/www/html/fusion/fusion_admin/updateuser.php on line 14
Fatal error: main(): Failed opening required
'fusion_langdiradmin/admin_members.php'
(include_path='.:/usr/share/pear') in
/var/www/html/fusion/fusion_admin/updateuser.php on line 14
* Second script is at fusion_admin/forums_prune.php.
Example:
http://localhost/fusion/fusion_admin/forums_prune.php
The output generated is roughly:
Fatal error: Call to undefined function:
opentable() in /var/www/html/fusion/fusion_admin/forums_prune.php on line
14
It is also possible to download or view the DB backup file from the DB and
use that to gain admin access. The readme file states:
1 - CHMOD the following folders to 0777:
- ---
- fusion_admin/db_backups
- ---
Which means that the db_backups file is browse-able and can be easily
retrieved
Examples:
- backup_2004-08-17_1845.sql
- backup_2004-08-17_1845.sql.gz
- backup_year-month-day_time.sql
- backup_year-month-day_time.sql.gz
