📄 Description (English)
Concrete CMS 9 before 9.5.0 is vulnerable to Cross Site Request Forgery (CSRF) at concrete/controllers/dialog/logs/delete. The The Concrete CMS security team gave this vulnerability a CVSS v.4.0 score of 2.3 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks Yonatan Drori (Tenzai) for reporting.
🤖 AI Executive Summary
Concrete CMS 9 before version 9.5.0 contains a Cross-Site Request Forgery (CSRF) vulnerability in the log deletion dialog controller that could allow attackers to perform unauthorized actions on behalf of authenticated users. While the CVSS v3.1 score of 8.8 indicates high severity, the CVSS v4.0 reassessment (2.3) suggests limited practical impact due to required user interaction and minimal consequences. No public exploit is currently available, but organizations using Concrete CMS should prioritize upgrading to version 9.5.0 or later.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using Concrete CMS for content management, particularly in government portals, educational institutions, and corporate websites, face moderate risk. The vulnerability primarily affects administrative functions (log deletion), limiting exposure to authenticated users. Government agencies under NCA oversight and organizations handling sensitive content management should prioritize patching. The impact is lower for banking and ARAMCO systems as they typically use enterprise-grade CMS solutions, but smaller government entities and educational institutions may be affected.

🔧 Remediation Steps (English)
1. IMMEDIATE ACTIONS:
- Identify all Concrete CMS 9.x installations in your environment
- Restrict administrative access to log management functions to trusted networks only
- Implement Web Application Firewall (WAF) rules to detect CSRF patterns in requests to /concrete/controllers/dialog/logs/delete
2. PATCHING GUIDANCE:
- Upgrade to Concrete CMS 9.5.0 or later immediately
- Test upgrades in non-production environments first
- Review release notes for breaking changes before deployment
3. COMPENSATING CONTROLS (if immediate patching not possible):
- Implement SameSite cookie attributes (SameSite=Strict) for session cookies
- Deploy CSRF tokens validation at application level
- Use Content Security Policy (CSP) headers to restrict cross-origin requests
- Implement additional authentication for sensitive operations (re-authentication for log deletion)
4. DETECTION RULES:
- Monitor for POST requests to /concrete/controllers/dialog/logs/delete without proper Referer headers
- Alert on log deletion activities from unexpected sources
- Track failed CSRF token validations in application logs
🔧 خطوات المعالجة (العربية)
1. الإجراءات الفورية:
- تحديد جميع تثبيتات Concrete CMS 9.x في بيئتك
- تقييد الوصول الإداري إلى وظائف إدارة السجلات إلى الشبكات الموثوقة فقط
- تنفيذ قواعد جدار الحماية لتطبيقات الويب (WAF) للكشف عن أنماط CSRF في الطلبات إلى /concrete/controllers/dialog/logs/delete
2. إرشادات التصحيح:
- الترقية إلى Concrete CMS 9.5.0 أو أحدث فوراً
- اختبار الترقيات في بيئات غير الإنتاج أولاً
- مراجعة ملاحظات الإصدار للتغييرات الجذرية قبل النشر
3. الضوابط البديلة (إذا لم يكن التصحيح الفوري ممكناً):
- تنفيذ سمات ملفات تعريف الارتباط SameSite (SameSite=Strict) لملفات جلسة العمل
- نشر التحقق من رموز CSRF على مستوى التطبيق
- استخدام رؤوس سياسة أمان المحتوى (CSP) لتقييد الطلبات عبر الأصول
- تنفيذ مصادقة إضافية للعمليات الحساسة (إعادة المصادقة لحذف السجلات)
4. قواعد الكشف:
- مراقبة طلبات POST إلى /concrete/controllers/dialog/logs/delete بدون رؤوس Referer مناسبة
- تنبيهات حول أنشطة حذف السجلات من مصادر غير متوقعة
- تتبع فشل التحقق من رموز CSRF في سجلات التطبيق
