🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Confluence Data Center and Server instances in your environment
2. Restrict network access to Confluence instances to authorized users only
3. Enable IP whitelisting and VPN-only access as temporary measure
4. Monitor admin account creation logs for suspicious activities
5. Review existing admin accounts for unauthorized additions

PATCHING:
1. Apply Atlassian security patches immediately (versions 7.19.17, 8.5.3, 8.6.1 or later)
2. Prioritize patching for internet-facing Confluence instances
3. Test patches in non-production environment first
4. Schedule maintenance window for production patching

DETECTION:
1. Monitor for POST requests to /admin/users/createuser endpoints
2. Alert on new admin account creation without change management tickets
3. Review authentication logs for failed login attempts followed by admin creation
4. Implement WAF rules to block unauthorized admin creation attempts

COMPENSATING CONTROLS (if patching delayed):
1. Implement network segmentation - restrict Confluence access to internal networks only
2. Deploy Web Application Firewall (WAF) with rules blocking admin creation endpoints
3. Enable MFA for all Confluence accounts
4. Implement continuous monitoring of admin account changes
5. Conduct daily audits of admin account modifications
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع مثيلات Confluence Data Center و Server في بيئتك
2. تقييد الوصول إلى شبكة Confluence للمستخدمين المصرح لهم فقط
3. تفعيل قائمة IP البيضاء والوصول عبر VPN كإجراء مؤقت
4. مراقبة سجلات إنشاء حسابات المسؤول للأنشطة المريبة
5. مراجعة حسابات المسؤول الموجودة للتحقق من الإضافات غير المصرح بها

التصحيح:
1. تطبيق تصحيحات أمان Atlassian فوراً (الإصدارات 7.19.17 و 8.5.3 و 8.6.1 أو أحدث)
2. إعطاء الأولوية لتصحيح مثيلات Confluence المتصلة بالإنترنت
3. اختبار التصحيحات في بيئة غير الإنتاج أولاً
4. جدولة نافذة صيانة لتصحيح الإنتاج

الكشف:
1. مراقبة طلبات POST إلى نقاط نهاية /admin/users/createuser
2. تنبيهات عند إنشاء حساب مسؤول جديد بدون تذاكر إدارة التغيير
3. مراجعة سجلات المصادقة لمحاولات تسجيل الدخول الفاشلة متبوعة بإنشاء مسؤول
4. تطبيق قواعد WAF لحظر محاولات إنشاء مسؤول غير مصرح بها
