📄 Description (English)
A vulnerability was identified in kodcloud KodExplorer up to 4.52. This impacts the function fileGet of the file /app/controller/share.class.php of the component fileGet Endpoint. Such manipulation of the argument fileUrl leads to improper authentication. The attack can be launched remotely. The vendor was contacted early about this disclosure but did not respond in any way.
🤖 AI Executive Summary
CVE-2026-6569 is a high-severity authentication bypass vulnerability in KodExplorer versions up to 4.52 affecting the fileGet endpoint. An attacker can manipulate the fileUrl parameter to bypass authentication controls and gain unauthorized access to files. With no patch available and no vendor response, organizations using KodExplorer face immediate risk of unauthorized file access and potential data exfiltration.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi organizations using KodExplorer for file management and collaboration. Government entities (NCA, CITC), financial institutions relying on document management systems, healthcare providers (MOH), and energy sector organizations (ARAMCO subsidiaries) are at risk. The authentication bypass could enable unauthorized access to sensitive documents, financial records, and operational data. Organizations in the education and research sectors using KodExplorer for collaborative file sharing are also vulnerable to data exfiltration and intellectual property theft.

🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all instances of KodExplorer running versions up to 4.52 across your infrastructure
2. Implement network-level access controls restricting access to the /app/controller/share.class.php endpoint
3. Monitor access logs for suspicious fileGet requests with unusual fileUrl parameters
4. Disable the fileGet endpoint if not critical to operations
Compensating Controls:
1. Implement Web Application Firewall (WAF) rules to validate and sanitize fileUrl parameters
2. Enforce strict input validation: reject fileUrl parameters containing path traversal sequences (../, ..\ , encoded variants)
3. Implement rate limiting on the fileGet endpoint to detect brute force attempts
4. Deploy authentication middleware requiring additional verification before file access
5. Enable comprehensive logging and alerting for all fileGet requests
Detection Rules:
1. Alert on fileGet requests with fileUrl parameters containing: ../, ..\, %2e%2e, encoded path traversal
2. Monitor for fileGet requests from unauthorized IP ranges or outside business hours
3. Track failed authentication attempts followed by successful file access
4. Alert on access to sensitive file paths via fileGet endpoint
Long-term:
1. Evaluate alternative file management solutions with active vendor support
2. Plan migration away from KodExplorer to patched/maintained alternatives
3. Implement zero-trust architecture for file access controls
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع نسخ KodExplorer التي تعمل بالإصدارات حتى 4.52 عبر البنية التحتية
2. تطبيق عناصر تحكم الوصول على مستوى الشبكة لتقييد الوصول إلى نقطة النهاية /app/controller/share.class.php
3. مراقبة سجلات الوصول للطلبات المريبة في fileGet بمعاملات fileUrl غير عادية
4. تعطيل نقطة نهاية fileGet إذا لم تكن حرجة للعمليات
عناصر التحكم التعويضية:
1. تطبيق قواعد جدار حماية تطبيقات الويب (WAF) للتحقق من صحة معاملات fileUrl وتنظيفها
2. فرض التحقق الصارم من المدخلات: رفض معاملات fileUrl التي تحتوي على تسلسلات اجتياز المسار
3. تطبيق تحديد معدل الطلبات على نقطة نهاية fileGet للكشف عن محاولات القوة الغاشمة
4. نشر برامج وسيطة للمصادقة تتطلب تحقق إضافي قبل الوصول إلى الملفات
5. تفعيل السجلات الشاملة والتنبيهات لجميع طلبات fileGet
قواعد الكشف:
1. التنبيه على طلبات fileGet بمعاملات fileUrl تحتوي على: ../, ..\, %2e%2e, اجتياز المسار المشفر
2. مراقبة طلبات fileGet من نطاقات IP غير مصرح بها أو خارج ساعات العمل
3. تتبع محاولات المصادقة الفاشلة متبوعة بالوصول الناجح إلى الملفات
4. التنبيه على الوصول إلى مسارات الملفات الحساسة عبر نقطة نهاية fileGet
المدى الطويل:
1. تقييم حلول إدارة الملفات البديلة مع دعم البائع النشط
2. التخطيط للهجرة بعيداً عن KodExplorer إلى بدائل مصححة/مدعومة
3. تطبيق معمارية الثقة الصفرية لعناصر تحكم الوصول إلى الملفات
