qEngine CMS 6.0.0 Database Backup Disclosure Exploit


Vendor: C97net
Product web page: http://www.c97.net
Affected version: 6.0.0 and 4.1.6

Summary: 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.

Desc: 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.


Tested on: Apache/2.4.7 (Win32)
PHP/5.5.6
MySQL 5.6.14
