🔧 Remediation Steps (English)
Immediate Actions:
1. Disable Synology Contacts functionality until patch is available or implement network segmentation
2. Restrict access to Synology Contacts to trusted internal networks only
3. Implement strict input validation and output encoding at application level
4. Monitor user activity logs for suspicious file access patterns
Compensating Controls:
1. Deploy Web Application Firewall (WAF) rules to detect and block XSS payloads in contact submissions
2. Implement Content Security Policy (CSP) headers to prevent inline script execution
3. Enable audit logging for all file read/write operations within Synology Contacts
4. Conduct user access reviews and enforce principle of least privilege
5. Implement email filtering to prevent external XSS payload injection
Detection Rules:
1. Monitor for script tags (<script>, <iframe>, event handlers) in contact form submissions
2. Alert on unusual file access patterns from Synology Contacts service account
3. Track changes to contact records with embedded HTML/JavaScript content
4. Monitor for base64-encoded payloads in contact fields
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تعطيل وظيفة Synology Contacts حتى توفر التصحيح أو تطبيق تقسيم الشبكة
2. تقييد الوصول إلى Synology Contacts للشبكات الداخلية الموثوقة فقط
3. تطبيق التحقق الصارم من المدخلات وترميز المخرجات على مستوى التطبيق
4. مراقبة سجلات نشاط المستخدم للأنماط المريبة في الوصول إلى الملفات
الضوابط التعويضية:
1. نشر قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن حمولات XSS وحجبها
2. تطبيق رؤوس سياسة أمان المحتوى (CSP) لمنع تنفيذ البرامج النصية المضمنة
3. تفعيل تسجيل التدقيق لجميع عمليات قراءة/كتابة الملفات
4. إجراء مراجعات الوصول للمستخدمين وفرض مبدأ الامتيازات الأقل
5. تطبيق تصفية البريد الإلكتروني لمنع حقن حمولات XSS الخارجية
قواعد الكشف:
1. مراقبة علامات البرامج النصية في تقديمات نماذج الاتصال
2. تنبيهات على أنماط الوصول غير المعتادة من حساب خدمة Synology Contacts
3. تتبع التغييرات في سجلات الاتصال التي تحتوي على محتوى HTML/JavaScript مضمن
4. مراقبة الحمولات المشفرة بـ base64 في حقول الاتصال
