Accellion FTA SQL Injection Vulnerability — Accellion FTA contains a SQL injection vulnerability exploited via a crafted host header in a request to document_root.html.

🤖 AI Executive Summary

Accellion FTA contains a critical SQL injection vulnerability (CVSS 9.0) exploitable through a crafted host header in requests to document_root.html. This vulnerability has active exploits available and affects secure file transfer appliances widely deployed in Saudi organizations. Immediate patching is essential as this vulnerability enables unauthenticated remote code execution and complete database compromise.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: Apr 20, 2026 08:51
🇸🇦 Saudi Arabia Impact Assessment
Critical impact on Saudi banking sector (SAMA-regulated institutions), government agencies (NCA oversight), healthcare organizations (MOH), and energy sector (ARAMCO, downstream companies). Accellion FTA is commonly used for secure document exchange in these sectors. Exploitation enables attackers to exfiltrate sensitive financial data, government documents, patient records, and operational technology information. Telecom operators (STC, Mobily) using FTA for customer data exchange are also at significant risk.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Accellion FTA instances in your environment (check network scans, asset inventory)
2. Isolate affected FTA appliances from production networks if patching cannot be completed within 24 hours
3. Enable enhanced logging on FTA systems to detect exploitation attempts
4. Review firewall rules to restrict access to document_root.html to trusted IP ranges only

PATCHING:
1. Apply Accellion security patches immediately (FTA versions prior to 9.12.411 are vulnerable)
2. Verify patch installation by checking FTA version in admin console
3. Restart FTA services after patching

COMPENSATING CONTROLS (if immediate patching impossible):
1. Implement Web Application Firewall (WAF) rules to block requests with suspicious host headers to document_root.html
2. Deploy IDS/IPS signatures to detect SQL injection patterns in HTTP requests
3. Restrict network access to FTA admin interfaces to VPN/bastion hosts only
4. Implement rate limiting on document_root.html endpoint

DETECTION:
1. Monitor for HTTP requests to document_root.html with non-standard Host headers
2. Alert on SQL keywords (UNION, SELECT, DROP, INSERT) in HTTP request parameters
3. Track database connection anomalies and unexpected query execution
4. Review FTA access logs for 401/403 errors followed by successful authentication
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع مثيلات Accellion FTA في بيئتك (تحقق من فحوصات الشبكة وجرد الأصول)
2. عزل أجهزة FTA المتأثرة عن شبكات الإنتاج إذا لم يتمكن التصحيح خلال 24 ساعة
3. تفعيل السجلات المحسنة على أنظمة FTA للكشف عن محاولات الاستغلال
4. مراجعة قواعد جدار الحماية لتقييد الوصول إلى document_root.html للنطاقات الموثوقة فقط

التصحيح:
1. تطبيق تصحيحات أمان Accellion فورًا (إصدارات FTA السابقة للإصدار 9.12.411 عرضة للخطر)
2. التحقق من تثبيت التصحيح بفحص إصدار FTA في وحدة التحكم الإدارية
3. إعادة تشغيل خدمات FTA بعد التصحيح

الضوابط البديلة (إذا كان التصحيح الفوري مستحيلاً):
1. تنفيذ قواعد جدار تطبيقات الويب (WAF) لحظر الطلبات برؤوس مضيف مريبة إلى document_root.html
2. نشر توقيعات IDS/IPS للكشف عن أنماط حقن SQL في طلبات HTTP
3. تقييد الوصول إلى واجهات إدارة FTA إلى أجهزة VPN/bastion فقط
4. تنفيذ تحديد معدل على نقطة نهاية document_root.html

الكشف:
1. مراقبة طلبات HTTP إلى document_root.html برؤوس مضيف غير قياسية
2. التنبيه على كلمات SQL الرئيسية (UNION, SELECT, DROP, INSERT) في معاملات طلب HTTP
3. تتبع شذوذ اتصال قاعدة البيانات وتنفيذ الاستعلام غير المتوقع
4. مراجعة سجلات وصول FTA للأخطاء 401/403 متبوعة بمصادقة ناجحة
