Timeline:
------------
2014-2018 - informed developers about multiple vulnerabilities in this and
other D-Link devices.
2017.08.28 - informed about it one USA company with bug bounty program -
they were interested in this device, but not in these vulnerabilities. Later
informed D-Link about them.
2017.10.28 - disclosed at my site (http://websecurity.com.ua/8720/).
