🔧 Remediation Steps (English)
1. IMMEDIATE ACTIONS:
- Identify all Concrete CMS 9 installations in your environment
- Document current versions and deployment locations
- Restrict administrative access to CMS interfaces where possible
- Review recent page deletion logs for suspicious activity
2. PATCHING GUIDANCE:
- Upgrade to Concrete CMS 9.5.0 or later when released
- Test patches in non-production environments first
- Plan maintenance windows for production upgrades
3. COMPENSATING CONTROLS (until patch available):
- Implement CSRF tokens validation at web application firewall level
- Use SameSite cookie attributes (Strict or Lax) for session cookies
- Enforce Content Security Policy (CSP) headers
- Implement additional authentication for bulk operations
- Restrict CMS admin panel access by IP whitelist
- Require re-authentication for sensitive operations like bulk deletion
4. DETECTION RULES:
- Monitor POST requests to /concrete/controllers/dialog/page/bulk/delete
- Alert on bulk page deletion operations from unusual sources
- Track failed CSRF token validations in application logs
- Monitor for cross-origin requests to CMS admin interfaces
🔧 خطوات المعالجة (العربية)
1. الإجراءات الفورية:
- تحديد جميع تثبيتات Concrete CMS 9 في بيئتك
- توثيق الإصدارات الحالية ومواقع النشر
- تقييد الوصول الإداري لواجهات CMS حيث أمكن
- مراجعة سجلات حذف الصفحات الأخيرة للنشاط المريب
2. إرشادات التصحيح:
- الترقية إلى Concrete CMS 9.5.0 أو أحدث عند إصداره
- اختبار التصحيحات في بيئات غير الإنتاج أولاً
- التخطيط لنوافذ الصيانة لترقيات الإنتاج
3. الضوابط البديلة (حتى توفر التصحيح):
- تطبيق التحقق من رموز CSRF على مستوى جدار الحماية
- استخدام سمات ملفات تعريف الارتباط SameSite (Strict أو Lax)
- تطبيق رؤوس سياسة أمان المحتوى (CSP)
- تطبيق مصادقة إضافية للعمليات الجماعية
- تقييد وصول لوحة تحكم CMS بقائمة IP البيضاء
- طلب إعادة المصادقة للعمليات الحساسة مثل الحذف الجماعي
4. قواعد الكشف:
- مراقبة طلبات POST إلى /concrete/controllers/dialog/page/bulk/delete
- تنبيهات على عمليات حذف الصفحات الجماعية من مصادر غير عادية
- تتبع فشل التحقق من رموز CSRF في سجلات التطبيق
- مراقبة الطلبات عبر الأصول إلى واجهات إدارة CMS
