🔧 Remediation Steps (English)
1. IMMEDIATE ACTIONS:
- Inventory all Cybozu Garoon deployments and identify instances running versions 5.0.0 through 6.0.3
- Restrict administrative access to portal settings through network segmentation and access controls
- Enable audit logging for all portal configuration changes
- Monitor for unauthorized modifications to portal settings in security logs
2. PATCHING GUIDANCE:
- Apply Cybozu security patches immediately to upgrade affected versions to 6.0.4 or later
- Test patches in non-production environments before production deployment
- Coordinate patching with change management to minimize business impact
3. COMPENSATING CONTROLS (if patching delayed):
- Implement Web Application Firewall (WAF) rules to detect and block suspicious input patterns targeting portal settings
- Restrict portal administration to specific IP ranges and require multi-factor authentication
- Implement role-based access control (RBAC) limiting who can modify portal configurations
4. DETECTION RULES:
- Monitor HTTP requests with unusual parameters targeting portal configuration endpoints
- Alert on failed authentication attempts followed by successful portal setting modifications
- Track changes to portal settings via audit logs and flag unauthorized modifications
- Search logs for CWE-231 patterns: unvalidated input to critical functions
🔧 خطوات المعالجة (العربية)
1. الإجراءات الفورية:
- حصر جميع نشرات Cybozu Garoon وتحديد الإصدارات من 5.0.0 إلى 6.0.3
- تقييد الوصول الإداري لإعدادات البوابة من خلال تقسيم الشبكة والتحكم في الوصول
- تفعيل تسجيل التدقيق لجميع تغييرات إعدادات البوابة
- مراقبة التعديلات غير المصرح بها على إعدادات البوابة في سجلات الأمان
2. إرشادات التصحيح:
- تطبيق تصحيحات أمان Cybozu فوراً للترقية إلى الإصدار 6.0.4 أو أحدث
- اختبار التصحيحات في بيئات غير الإنتاج قبل النشر
- تنسيق التصحيح مع إدارة التغيير لتقليل تأثير الأعمال
3. الضوابط البديلة (إذا تأخر التصحيح):
- تطبيق قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن أنماط المدخلات المريبة
- تقييد إدارة البوابة على نطاقات IP محددة وتطلب المصادقة متعددة العوامل
- تطبيق التحكم في الوصول القائم على الأدوار (RBAC) لتحديد من يمكنه تعديل الإعدادات
4. قواعد الكشف:
- مراقبة طلبات HTTP بمعاملات غير عادية تستهدف نقاط نهاية إعدادات البوابة
- تنبيهات محاولات المصادقة الفاشلة متبوعة بتعديلات ناجحة لإعدادات البوابة
- تتبع التغييرات على إعدادات البوابة عبر سجلات التدقيق والإشارة إلى التعديلات غير المصرح بها
