Technical details

The vulnerability exists in the com.adups.fota.sysoper.provider.InfoProvider content provider within the com.adups.fota.sysoper package. The application is configured with the android:sharedUserId attribute set to 'android.uid.system', causing it to execute with elevated system privileges. Because the content provider is improperly secured, any third-party application installed on the device can interact with it to perform file operations (read, write, delete) as the system user. This allows for the unauthorized extraction of PII, including SMS messages and call logs, by bypassing the Android permission model.
