🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Cisco HyperFlex HX Installer VMs in your environment and document their network locations
2. Isolate affected HyperFlex systems from untrusted networks immediately
3. Implement network segmentation to restrict access to HyperFlex management interfaces
4. Enable logging and monitoring on all HyperFlex systems for suspicious command execution
PATCHING:
1. Apply Cisco security patches for HyperFlex HX Installer immediately (check Cisco Security Advisory for specific version numbers)
2. Test patches in non-production environment first
3. Schedule maintenance windows for production systems and apply patches within 48 hours
4. Verify patch installation by checking system version post-update
COMPENSATING CONTROLS (if patching delayed):
1. Restrict network access to HyperFlex Installer VM to authorized administrators only
2. Implement firewall rules to block external access to HyperFlex management ports
3. Disable unnecessary services on the Installer VM
4. Implement Web Application Firewall (WAF) rules to filter malicious input patterns
DETECTION:
1. Monitor for HTTP requests containing shell metacharacters (;, |, &, $, `, >, <) to HyperFlex endpoints
2. Alert on any command execution attempts from HyperFlex Installer VM
3. Review system logs for root-level process execution from web service accounts
4. Monitor for unexpected outbound connections from HyperFlex systems
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع أجهزة Cisco HyperFlex HX Installer VM في بيئتك وقم بتوثيق مواقعها على الشبكة
2. عزل أنظمة HyperFlex المتأثرة عن الشبكات غير الموثوقة فوراً
3. تطبيق تقسيم الشبكة لتقييد الوصول إلى واجهات إدارة HyperFlex
4. تفعيل السجلات والمراقبة على جميع أنظمة HyperFlex للكشف عن تنفيذ الأوامر المريبة
التصحيح:
1. تطبيق تصحيحات أمان Cisco لـ HyperFlex HX Installer فوراً (تحقق من مستشار أمان Cisco للحصول على أرقام الإصدارات المحددة)
2. اختبار التصحيحات في بيئة غير الإنتاج أولاً
3. جدولة نوافذ الصيانة للأنظمة الإنتاجية وتطبيق التصحيحات خلال 48 ساعة
4. التحقق من تثبيت التصحيح بفحص إصدار النظام بعد التحديث
الضوابط البديلة (إذا تأخر التصحيح):
1. تقييد الوصول إلى شبكة Installer VM لـ HyperFlex للمسؤولين المصرح لهم فقط
2. تطبيق قواعد جدار الحماية لحظر الوصول الخارجي إلى منافذ إدارة HyperFlex
3. تعطيل الخدمات غير الضرورية على Installer VM
4. تطبيق قواعد جدار تطبيقات الويب لتصفية أنماط الإدخال الضارة
الكشف:
1. مراقبة طلبات HTTP التي تحتوي على أحرف shell (;, |, &, $, `, >, <) إلى نقاط نهاية HyperFlex
2. تنبيه عند أي محاولات تنفيذ أوامر من Installer VM
3. مراجعة سجلات النظام لتنفيذ العمليات على مستوى root من حسابات خدمة الويب
4. مراقبة الاتصالات الخارجية غير المتوقعة من أنظمة HyperFlex
