Official description
Ekia File Manager 1.2.7 exposes com.ekia.filecontrolmanager.OpenFileProvider as an exported Android ContentProvider without requiring caller permissions. The provider maps the caller-controlled URI path directly to a filesystem path and passes it to new File(...). It then supports query(), openFile(), and delete() operations. Because the provider is exported and lacks android:permission, android:readPermission, or android:writePermission, another local application can access the provider authority and cause File Manager's process to read, create, overwrite, or delete files that are accessible to that process.

The underlying weakness: Improper Export of Android Application Components
The Android application exports a component for use by other applications, but does not properly restrict which applications can launch the component or access the data it contains.
How developers prevent this class of flaw
- If they do not need to be shared by other applications, explicitly mark components with android:exported=false in the application manifest.
- If you only intend to use exported components between related apps under your control, use android:protectionLevel=signature in the xml manifest to restrict access to applications signed by you.
- Limit Content Provider permissions (read/write) as appropriate.
