CVE-2017-3192 is a critical-severity flaw (CVSS 9.8) affecting dir-130 firmware, dir-330 firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

D-Link DIR-130 firmware version 1.23 and DIR-330 firmware version 1.12 do not sufficiently protect administrator credentials. The tools_admin.asp page discloses the administrator password in base64 encoding in the returned web page. A remote attacker with access to this page (potentially through a authentication bypass such as CVE-2017-3191) may obtain administrator credentials for the device.
