Technical details

The Adups FOTA application (com.adups.fota.sysoper) on BLU R1 HD devices contains an insecurely configured Content Provider named com.adups.fota.sysoper.provider.InfoProvider. Because the application is configured with the 'android.uid.system' shared user ID, it executes with elevated system privileges. Any third-party application installed on the device can interact with this provider to perform file operations (read/write/delete) as the system user. This allows attackers to modify secure settings to intercept notifications or access the accounts database to steal authentication tokens.
