Subject: Broken TLS certificate validation in VTech DigiGo browser

------------------------------------------------------------------------
Broken TLS certificate validation in VTech DigiGo browser
------------------------------------------------------------------------
Sipke Mellema, September 2017

------------------------------------------------------------------------
Abstract
------------------------------------------------------------------------
VTech's DigiGo is a hand held smart device for children. The web browser
included in the DigiGo does not validate TLS certificates when creating
secure connections, allowing man in the middle attacks on web traffic.

------------------------------------------------------------------------
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 30 November,
2017. The firmware version still displays as 83.60630.
