🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all instances of Sanluan PublicCMS 5.202506.d in your environment and document their criticality
2. Disable or restrict access to the templateResult API endpoint immediately using WAF rules or network segmentation
3. Implement input validation: reject any templateContent parameters containing template syntax characters (${, #{, <%, etc.)
4. Enable detailed logging for all templateResult API calls and monitor for suspicious patterns
COMPENSATING CONTROLS:
5. Deploy Web Application Firewall (WAF) rules to block requests with template injection payloads
6. Implement strict Content Security Policy (CSP) headers to limit template execution scope
7. Run the application with minimal privileges and in isolated containers
8. Apply network segmentation to limit lateral movement if compromise occurs
DETECTION RULES:
9. Monitor for requests to /templateResult endpoint with special characters: $, #, {, }, <, %, etc.
10. Alert on any template processing errors or unexpected code execution attempts
11. Track changes to template files and configuration
LONG-TERM:
12. Evaluate alternative CMS solutions with active vendor support
13. Plan migration away from Sanluan PublicCMS given vendor non-responsiveness
14. Conduct security assessment of all custom template implementations
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع حالات Sanluan PublicCMS 5.202506.d في بيئتك وتوثيق أهميتها
2. عطّل أو قيّد الوصول إلى نقطة نهاية واجهة برمجة تطبيقات templateResult فوراً باستخدام قواعد WAF أو تقسيم الشبكة
3. تطبيق التحقق من صحة المدخلات: رفض أي معاملات templateContent تحتوي على أحرف بناء جملة القالب (${ و #{ و <% وما إلى ذلك)
4. تفعيل السجلات التفصيلية لجميع استدعاءات واجهة برمجة تطبيقات templateResult ومراقبة الأنماط المريبة
الضوابط التعويضية:
5. نشر قواعد جدار الحماية (WAF) لحجب الطلبات التي تحتوي على حمولات حقن القوالب
6. تطبيق رؤوس سياسة أمان المحتوى (CSP) الصارمة لتحديد نطاق تنفيذ القالب
7. تشغيل التطبيق بامتيازات دنيا وفي حاويات معزولة
8. تطبيق تقسيم الشبكة لتحديد الحركة الجانبية في حالة الاختراق
قواعد الكشف:
9. مراقبة الطلبات إلى نقطة نهاية /templateResult بأحرف خاصة: $ و # و { و } و < و % وما إلى ذلك
10. تنبيه أخطاء معالجة القالب غير المتوقعة أو محاولات تنفيذ الكود
11. تتبع التغييرات في ملفات القالب والتكوين
المدى الطويل:
12. تقييم حلول نظام إدارة المحتوى البديلة مع دعم البائع النشط
13. التخطيط للهجرة بعيداً عن Sanluan PublicCMS نظراً لعدم استجابة البائع
14. إجراء تقييم أمني لجميع تطبيقات القالب المخصصة
