🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all systems running idachev mcp-javadc versions up to 1.2.4 across your infrastructure
2. Isolate affected systems from production networks if possible, or implement network segmentation
3. Disable HTTP Interface access to mcp-javadc if not actively required
4. Implement strict input validation and WAF rules blocking special characters in jarFilePath parameter

PATCHING GUIDANCE:
1. Contact idachev project for security patch availability and timeline
2. Monitor project repository for patch releases
3. Prepare upgrade plan to patched version once available
4. Test patches in isolated environment before production deployment

COMPENSATING CONTROLS (until patch available):
1. Implement network-level access controls restricting HTTP Interface to trusted IPs only
2. Deploy Web Application Firewall (WAF) rules to detect/block command injection patterns in jarFilePath
3. Monitor HTTP logs for suspicious jarFilePath parameters containing: |, ;, &, $(), backticks, >, <, newlines
4. Implement application-level input validation rejecting non-alphanumeric characters in file paths
5. Run mcp-javadc with minimal privileges (non-root user)
6. Enable comprehensive logging and alerting on HTTP Interface access

DETECTION RULES:
1. Alert on HTTP requests to mcp-javadc containing shell metacharacters in jarFilePath parameter
2. Monitor for unexpected child process spawning from mcp-javadc process
3. Track file system modifications in unexpected directories initiated by mcp-javadc
4. Log all HTTP Interface authentication attempts and parameter values
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع الأنظمة التي تقوم بتشغيل إصدارات idachev mcp-javadc حتى 1.2.4 عبر البنية التحتية الخاصة بك
2. عزل الأنظمة المتأثرة عن شبكات الإنتاج إن أمكن، أو تطبيق تقسيم الشبكة
3. تعطيل وصول واجهة HTTP إلى mcp-javadc إذا لم تكن مطلوبة بنشاط
4. تطبيق التحقق الصارم من المدخلات وقواعد WAF لحظر الأحرف الخاصة في معامل jarFilePath

إرشادات التصحيح:
1. الاتصال بمشروع idachev للحصول على توفر التصحيح الأمني والجدول الزمني
2. مراقبة مستودع المشروع لإصدارات التصحيح
3. تحضير خطة الترقية إلى الإصدار المصحح بمجرد توفره
4. اختبار التصحيحات في بيئة معزولة قبل نشر الإنتاج

الضوابط البديلة (حتى توفر التصحيح):
1. تطبيق ضوابط الوصول على مستوى الشبكة لتقييد واجهة HTTP إلى عناوين IP موثوقة فقط
2. نشر قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن أنماط حقن الأوامر وحظرها في jarFilePath
3. مراقبة سجلات HTTP للمعاملات المريبة في jarFilePath التي تحتوي على: |، ;، &، $()، علامات الاقتباس العكسية، >، <، أسطر جديدة
4. تطبيق التحقق من المدخلات على مستوى التطبيق برفض الأحرف غير الأبجدية الرقمية في مسارات الملفات
5. تشغيل mcp-javadc بامتيازات دنيا (مستخدم غير جذر)
6. تفعيل السجلات الشاملة والتنبيهات على وصول واجهة HTTP

قواعد الكشف:
1. التنبيه على طلبات HTTP إلى mcp-javadc التي تحتوي على أحرف shell metacharacters في معامل jarFilePath
2. مراقبة توليد عمليات فرعية غير متوقعة من عملية mcp-javadc
3. تتبع تعديلات نظام الملفات في الدلائل غير المتوقعة التي بدأتها mcp-javadc
4. تسجيل جميع محاولات المصادقة على واجهة HTTP وقيم المعاملات
