التطبيق يعالج هذه المعاملات مباشرة ويمررها إلى مساعدات تنفيذ أوامر RPC دون:
- التحقق من المصادقة
- التحقق من صحة الإدخال/تنقيته
- فرض قائمة بيضاء للطرق
- فحص أنواع المعاملات

وهذا يسمح للمهاجمين بتحديد طرق واجهة Dubbo عشوائية تنفذ أوامر النظام.

**سجلات التطبيق:**

- استثناءات أو أخطاء متعلقة باستدعاء RPC الخاص بـ Dubbo
- تحذيرات حول معاملات غير مُتحقق منها في سجلات إطار عمل RPC
- ClassNotFoundException أو فشل في استدعاء الدوال
- محاولات غير متوقعة لحل الواجهات

### مؤشرات على مستوى المضيف

- عمليات فرعية غير متوقعة تم إنشاؤها من عملية Weaver Java
- حسابات مستخدمين جديدة تم إنشاؤها على النظام
- اتصالات شبكة غير متوقعة من خدمة Weaver
- تعديل ملفات إعدادات Weaver
- وجود webshells في أدلة Weaver
- كتابة ملفات غير معتادة إلى أدلة النظام
- إدخالات مشبوهة في cronjob أو الخدمات

### مؤشرات على مستوى نظام الملفات

- ملفات غير متوقعة في `/tmp/` أو `/var/tmp/`
- ملفات JAR الخاصة بـ Weaver أو ملفات الإعدادات المعدلة
- سكربتات شل جديدة في أدلة يمكن الوصول إليها عبر الويب
- وجود أسماء ملفات webshell شائعة (shell.jsp، cmd.jsp، إلخ.)

## المعالجة

### إجراءات فورية (0-24 ساعة)

1. **تعطيل الوصول إلى نقطة نهاية التصحيح عبر الشبكة**

   أضف قاعدة جدار حماية لمنع الوصول إلى نقطة النهاية الضعيفة:   ```
