| Low | App is direct-boot aware [android:directBootAware=true] This app can run before the user unlocks the device. If you're using a custom subclass of Application, and if any component inside your application is direct - boot aware, then your entire custom application is considered to be direct - boot aware.During Direct Boot, your application can only access the data that is stored in device protected storage. |
| High | Service (com.sec.spp.push.RequestService) is not Protected. [android:exported=true] A Service is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device. |
| High | Broadcast Receiver (com.sec.spp.push.StartupReceiver) is not Protected.An intent-filter exists. A Broadcast Receiver is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device. The presence of intent-filter indicates that the Broadcast Receiver is explicitly exported. |

| Low | Broadcast Receiver (com.sec.spp.push.receiver.SessionRefreshRequestReceiver) is Protected by a permission, but the protection level of the permission should be checked.Permission: com.sec.spp.push.permission.REQUESTprotectionLevel: signatureOrSystem [android:exported=true] A Broadcast Receiver is found to be exported, but is protected by a permission. However, the protection level of the permission is set to signatureOrSystem. It is recommended that signature level is used instead. Signature level should suffice for most purposes, and does not depend on where the applications are installed on the device. |
| High | Broadcast Receiver (com.sec.spp.push.receiver.SaSigninClickReceiver) is Protected by a permission, but the protection level of the permission should be checked.Permission: com.osp.app.signin.SIGNIN_CLICK_BROADCAST_PERMISSION [android:exported=true] A Broadcast Receiver is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device. It is protected by a permission which is not defined in the analysed application. As a result, the protection level of the permission should be checked where it is defined. If it is set to normal or dangerous, a malicious application can request and obtain the permission and interact with the component. If it is set to signature, only applications signed with the same certificate can obtain the permission. |
