Abstract
------------------------------------------------------------------------

VTech's DigiGo is a hand held smart device for children. The device
contains a browser that allows children to connect to websites on a
whitelist. Attackers can remotely add an entry to the whitelist to
perform a persistent overlay attack on the browser app.

------------------------------------------------------------------------

Tested versions
------------------------------------------------------------------------

This issue was tested on a VTech DigiGo running firmware version
83.60630. It is likely that other versions are also affected.

------------------------------------------------------------------------

Fix
------------------------------------------------------------------------

VTech pushed a firmware update to address this issue on 6 November,
2017. The firmware version still displays as 83.60630.
