📄 Description (English)
A security vulnerability has been detected in geekgod382 filesystem-mcp-server 1.0.0. This issue affects the function is_path_allowed of the file server.py of the component read_file_tool/write_file_tool. Such manipulation leads to path traversal. The attack can be launched remotely. The exploit has been disclosed publicly and may be used. Upgrading to version 1.1.0 is capable of addressing this issue. The name of the patch is 45364545fc60dc80aadcd4379f08042d3d3d292e. Upgrading the affected component is advised.
🤖 AI Executive Summary
CVE-2026-7400 is a path traversal vulnerability in filesystem-mcp-server 1.0.0 affecting file read/write operations. The vulnerability allows remote attackers to bypass path validation controls and access unauthorized files on affected systems. With a CVSS score of 7.3 and public disclosure, this poses a significant risk to organizations using this component for file operations.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all systems running filesystem-mcp-server 1.0.0 across your infrastructure
2. Isolate affected systems from production networks if possible
3. Review access logs for suspicious file access patterns (../ sequences, unusual file paths)
4. Implement network-level restrictions limiting access to the affected service
PATCHING:
1. Upgrade to filesystem-mcp-server version 1.1.0 immediately (patch: 45364545fc60dc80aadcd4379f08042d3d3d292e)
2. Test the upgrade in a staging environment before production deployment
3. Verify the is_path_allowed function properly validates all file paths
COMPENSATING CONTROLS (if upgrade delayed):
1. Implement strict input validation on all file path parameters
2. Use Web Application Firewall (WAF) rules to block requests containing ../ or similar traversal patterns
3. Apply principle of least privilege - restrict service account file system permissions
4. Implement file access monitoring and alerting for unauthorized path access attempts
5. Use chroot/containerization to limit filesystem scope
DETECTION:
1. Monitor for HTTP requests containing: ../, ..\, %2e%2e, encoded traversal sequences
2. Alert on file access attempts outside designated directories
3. Log all read_file_tool and write_file_tool function calls with full parameters
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع الأنظمة التي تقوم بتشغيل filesystem-mcp-server 1.0.0 عبر البنية التحتية الخاصة بك
2. عزل الأنظمة المتأثرة عن شبكات الإنتاج إن أمكن
3. مراجعة سجلات الوصول للبحث عن أنماط وصول ملفات مريبة (تسلسلات ../)
4. تطبيق قيود على مستوى الشبكة لتحديد الوصول إلى الخدمة المتأثرة
التصحيح:
1. الترقية إلى filesystem-mcp-server الإصدار 1.1.0 فوراً (الرقعة: 45364545fc60dc80aadcd4379f08042d3d3d292e)
2. اختبار الترقية في بيئة التجريب قبل نشر الإنتاج
3. التحقق من أن دالة is_path_allowed تتحقق بشكل صحيح من جميع مسارات الملفات
عناصر التحكم البديلة:
1. تطبيق التحقق الصارم من المدخلات على جميع معاملات مسار الملف
2. استخدام قواعد جدار الحماية (WAF) لحظر الطلبات التي تحتوي على ../ أو أنماط اجتياز مماثلة
3. تطبيق مبدأ أقل امتياز - تقييد أذونات نظام الملفات لحساب الخدمة
4. تطبيق مراقبة التنبيهات لمحاولات الوصول غير المصرح بها
5. استخدام chroot/containerization لتحديد نطاق نظام الملفات
الكشف:
1. مراقبة طلبات HTTP التي تحتوي على: ../, ..\, %2e%2e
2. التنبيه على محاولات الوصول إلى الملفات خارج الدلائل المعينة
3. تسجيل جميع استدعاءات دوال read_file_tool و write_file_tool
