📄 Description (English)
Substance3D - Designer versions 15.1.0 and earlier are affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could lead to arbitrary file system read. An attacker could exploit this vulnerability to access sensitive files and directories outside the intended access scope. Exploitation of this issue requires user interaction in that a victim must open a malicious file. Scope is changed.
🤖 AI Executive Summary
Adobe Substance3D Designer versions 15.1.0 and earlier contain a path traversal vulnerability (CVE-2026-34664) allowing arbitrary file system read access. The vulnerability requires user interaction to open a malicious file and has a CVSS score of 6.3 (medium). Currently, no patch is available, making immediate compensating controls essential for organizations using this design software.

🔧 Remediation Steps (English)
Immediate Actions:
1. Restrict Substance3D Designer usage to trusted, isolated environments until patching is available
2. Disable file opening from untrusted sources and implement email attachment scanning for .spp, .psb, and related design file formats
3. Educate users not to open design files from unknown or suspicious sources
Compensating Controls:
1. Implement application whitelisting to restrict Designer execution to specific directories
2. Deploy file integrity monitoring on sensitive directories (Documents, Desktop, shared drives) to detect unauthorized file access attempts
3. Use network segmentation to isolate workstations running Substance3D from sensitive systems
4. Enable audit logging for file system access and monitor for suspicious path traversal patterns
5. Implement Data Loss Prevention (DLP) rules to prevent exfiltration of sensitive files accessed through this vulnerability
Detection Rules:
1. Monitor for Substance3D Designer processes accessing files outside standard installation and user document directories
2. Alert on file access patterns containing "../" or "..\" sequences initiated by Designer process
3. Track unusual file read operations on system directories (/etc, /windows/system32, /etc/passwd equivalents)
4. Monitor for Designer process spawning child processes or network connections
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تقييد استخدام Substance3D Designer في بيئات موثوقة ومعزولة حتى يتوفر التصحيح
2. تعطيل فتح الملفات من مصادر غير موثوقة وتطبيق فحص المرفقات البريدية لصيغ الملفات المتعلقة
3. تثقيف المستخدمين بعدم فتح ملفات التصميم من مصادر غير معروفة أو مريبة
الضوابط التعويضية:
1. تطبيق قائمة التطبيقات المسموحة لتقييد تنفيذ Designer في مجلدات محددة
2. نشر مراقبة سلامة الملفات على المجلدات الحساسة للكشف عن محاولات الوصول غير المصرح بها
3. استخدام تقسيم الشبكة لعزل محطات العمل التي تقوم بتشغيل Substance3D عن الأنظمة الحساسة
4. تفعيل تسجيل التدقيق لوصول نظام الملفات ومراقبة أنماط اجتياز المسار المريبة
5. تطبيق قواعد منع فقدان البيانات لمنع تسرب الملفات الحساسة
قواعد الكشف:
1. مراقبة عمليات Substance3D Designer التي تصل إلى الملفات خارج مجلدات التثبيت والمستندات
2. التنبيه على أنماط الوصول إلى الملفات التي تحتوي على تسلسلات "../" أو "..\"
3. تتبع عمليات القراءة غير العادية على مجلدات النظام
4. مراقبة عمليات Designer التي تولد عمليات فرعية أو اتصالات شبكية
