qEngine CMS 6.0.0 Database Backup Disclosure Exploit

Title: qEngine CMS 6.0.0 Database Backup Disclosure Exploit
Advisory ID: ZSL-2014-5172
Type: Local/Remote
Impact: Exposure of Sensitive Information
Risk: (3/5)
Release Date: 25.03.2014
qEngine (qE) is a lightweight, fast, yet feature packed CMS script to help you building your site quickly. Using template engine to separate the php codes from the design, you don't need to touch the codes to design your web site. qE is also expandable by using modules.
qEngine CMS stores database backups using the Backup DB tool with a predictable file name inside the '/admin/backup' directory as 'Full Backup YYYYMMDD.sql' or 'Full Backup YYYYMMDD.gz', which can be exploited to disclose sensitive information by downloading the file. The '/admin/backup' is also vulnerable to directory listing by default.
