I can concur these issues exist in several other models as well. In fact, on any UPnP enabled D-Link from 868L and down, merely selecting "Display Hidden Elements" inside the developer tool bar, will expose the entire administrative GUI. Additional models I found the same bug, though I'm so sure that the latest firmware completely fixes the issues.
