Bluebird devices contain a pre-loaded kiosk application. This application exposes an unsecured service provider "com.bluebird.kiosk.launcher.IpartnerKioskRemoteService". A local attacker can bind to the AIDL-type service to modify device's global settings and wallpaper image. This issue affects all versions before 1.1.2.
Bluebird devices contain a pre-loaded barcode scanner application. This application exposes an unsecured broadcast receiver "kr.co.bluebird.android.bbsettings.BootReceiver". A local attacker can call the receiver to overwrite file containing ".json" keyword with default barcode config file. It is possible to overwrite file in any location due to lack of protection against path traversal in name of the file. This issue affects all versions before 1.3.3.
