📄 Description (English)
CMDBuild 3.3.2 contains multiple stored cross-site scripting vulnerabilities that allow authenticated attackers to inject arbitrary web script or HTML via crafted input in card creation and file upload endpoints. Attackers can inject XSS payloads through Employee card parameters or SVG file attachments in the classes endpoint, which execute when other users view the affected records or preview attachments.
🤖 AI Executive Summary
CMDBuild 3.3.2 contains multiple stored XSS vulnerabilities in card creation and file upload endpoints that allow authenticated attackers to inject malicious scripts. These vulnerabilities execute when other users view affected records or preview attachments, potentially leading to session hijacking, credential theft, and lateral movement within enterprise networks. The lack of available patches and no public exploits present a moderate but persistent risk requiring immediate compensating controls.

🇸🇦 Saudi Arabia Impact Assessment
Saudi government agencies and critical infrastructure operators using CMDBuild for asset management and configuration tracking face significant risk. Banking sector (SAMA-regulated institutions) utilizing CMDBuild for IT asset management could experience unauthorized access to sensitive financial systems. Telecommunications providers (STC, Mobily) managing network infrastructure through CMDBuild are vulnerable to lateral movement attacks. Healthcare organizations using CMDBuild for medical device inventory management could face patient data exposure. Energy sector (ARAMCO, SEC) relying on CMDBuild for operational technology asset tracking could enable supply chain attacks. The stored XSS nature means persistent compromise of shared asset databases affecting multiple users simultaneously.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Restrict CMDBuild 3.3.2 access to trusted internal networks only; disable external access
2. Implement strict input validation and output encoding on all card creation and file upload endpoints
3. Enforce Content Security Policy (CSP) headers with strict-dynamic and nonce-based script execution
4. Disable SVG file uploads or implement strict SVG sanitization (remove script tags, event handlers)
5. Conduct immediate audit of all Employee cards and file attachments for malicious payloads
COMPENSATING CONTROLS:
6. Deploy Web Application Firewall (WAF) rules to detect and block XSS patterns in POST requests to /card and /classes endpoints
7. Implement HTML sanitization library (DOMPurify, Bleach) for all user-generated content
8. Enable detailed logging and monitoring of card modifications and file uploads with SIEM integration
9. Restrict file upload types to non-executable formats; implement file type validation on both client and server
10. Require multi-factor authentication for CMDBuild access to limit authenticated attacker surface
DETECTION:
11. Monitor for suspicious JavaScript patterns in card parameters: <script>, onerror=, onload=, javascript:
12. Alert on SVG uploads containing <script> tags or event handlers
13. Track unusual access patterns to recently modified cards by multiple users
14. Upgrade to CMDBuild 3.4.0+ when available and test thoroughly before production deployment
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تقييد وصول CMDBuild 3.3.2 إلى الشبكات الداخلية الموثوقة فقط؛ تعطيل الوصول الخارجي
2. تنفيذ التحقق الصارم من المدخلات وترميز المخرجات على جميع نقاط نهاية إنشاء البطاقات وتحميل الملفات
3. فرض رؤوس سياسة أمان المحتوى (CSP) مع تنفيذ النصوص البرمجية القائمة على strict-dynamic و nonce
4. تعطيل تحميل ملفات SVG أو تنفيذ تطهير صارم لـ SVG (إزالة علامات البرنامج النصي ومعالجات الأحداث)
5. إجراء تدقيق فوري لجميع بطاقات الموظفين والمرفقات بحثاً عن حمولات ضارة
الضوابط التعويضية:
6. نشر قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن أنماط XSS وحجبها في طلبات POST إلى نقاط النهاية
7. تنفيذ مكتبة تطهير HTML (DOMPurify, Bleach) لجميع المحتوى الذي ينشئه المستخدم
8. تفعيل السجلات التفصيلية ومراقبة تعديلات البطاقات وتحميل الملفات مع تكامل SIEM
9. تقييد أنواع تحميل الملفات إلى تنسيقات غير قابلة للتنفيذ؛ تنفيذ التحقق من نوع الملف على العميل والخادم
10. طلب المصادقة متعددة العوامل لوصول CMDBuild لتقليل سطح المهاجم المصرح
الكشف:
11. مراقبة أنماط JavaScript المريبة في معاملات البطاقات
12. تنبيهات على تحميل SVG التي تحتوي على علامات برنامج نصي أو معالجات أحداث
13. تتبع أنماط الوصول غير العادية للبطاقات المعدلة مؤخراً من قبل مستخدمين متعددين
14. الترقية إلى CMDBuild 3.4.0+ عند توفره واختباره بدقة قبل نشر الإنتاج
