🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all instances of Adobe Substance3D Stager in your environment using asset inventory tools
2. Restrict file opening from untrusted sources until patching is complete
3. Disable Substance3D Stager if not actively required
Patching Guidance:
1. Update to Adobe Substance3D Stager version 3.1.8 or later immediately
2. Prioritize patching for systems handling external files or collaborative projects
3. Test patches in non-production environments before full deployment
Compensating Controls (if immediate patching not possible):
1. Implement application whitelisting to restrict Substance3D execution
2. Use file integrity monitoring on .stp, .step, .obj, .fbx, and other 3D model files
3. Restrict file access permissions to read-only where possible
4. Disable file preview functionality in file managers
Detection Rules:
1. Monitor for Substance3D Stager process crashes or unexpected terminations
2. Alert on Substance3D Stager spawning child processes (cmd.exe, powershell.exe)
3. Log all file opens with Substance3D Stager, especially from email or downloads
4. Monitor for memory corruption indicators in application logs
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع نسخ Adobe Substance3D Stager في بيئتك باستخدام أدوات جرد الأصول
2. تقييد فتح الملفات من مصادر غير موثوقة حتى يتم إكمال التصحيح
3. تعطيل Substance3D Stager إذا لم يكن مطلوباً بنشاط
إرشادات التصحيح:
1. التحديث إلى Adobe Substance3D Stager الإصدار 3.1.8 أو أحدث فوراً
2. إعطاء الأولوية لتصحيح الأنظمة التي تتعامل مع الملفات الخارجية أو المشاريع التعاونية
3. اختبار التصحيحات في بيئات غير الإنتاج قبل النشر الكامل
الضوابط البديلة (إذا لم يكن التصحيح الفوري ممكناً):
1. تنفيذ قائمة بيضاء للتطبيقات لتقييد تنفيذ Substance3D
2. استخدام مراقبة سلامة الملفات على ملفات النماذج ثلاثية الأبعاد
3. تقييد أذونات الوصول إلى الملفات للقراءة فقط حيث أمكن
4. تعطيل وظيفة معاينة الملفات في مديري الملفات
قواعد الكشف:
1. مراقبة أعطال عملية Substance3D Stager أو الإنهاء غير المتوقع
2. التنبيه عند قيام Substance3D Stager بإنشاء عمليات فرعية
3. تسجيل جميع فتح الملفات باستخدام Substance3D Stager، خاصة من البريد الإلكتروني
4. مراقبة مؤشرات تلف الذاكرة في سجلات التطبيق
