📄 Description (English)

OpenHarness before commit bd4df81 contains a permission bypass vulnerability that allows attackers to read sensitive files by exploiting incomplete path normalization in the permission checker. Attackers can invoke the built-in grep and glob tools with sensitive root directories that are not properly evaluated against configured path rules, allowing disclosure of sensitive local file content, key material, configuration files, or directory contents despite configured path restrictions.

🤖 AI Executive Summary

CVE-2026-40515 is a permission bypass vulnerability in OpenHarness that allows attackers to read sensitive files through incomplete path normalization in the permission checker. By exploiting this flaw, attackers can use built-in grep and glob tools to access restricted directories and disclose sensitive data including keys, configurations, and directory contents. With a CVSS score of 7.5 and no patch currently available, this poses a significant risk to organizations using OpenHarness for infrastructure automation and configuration management.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi government agencies (NCA, NCSC), financial institutions (SAMA-regulated banks), and critical infrastructure operators (ARAMCO, SEC, telecom providers like STC and Mobily) that may use OpenHarness for infrastructure automation and configuration management. The ability to bypass permission controls and access sensitive files could lead to disclosure of cryptographic keys, API credentials, database connection strings, and classified government configurations. Organizations in the energy sector and financial services are particularly vulnerable due to their reliance on automated infrastructure management tools.

🔧 Remediation Steps (English)
Immediate Actions:
1. Audit all OpenHarness deployments to identify instances and their access scope
2. Review access logs for suspicious grep/glob tool invocations with unusual path parameters
3. Implement network segmentation to restrict OpenHarness access to trusted networks only
4. Disable or restrict access to built-in grep and glob tools if not essential for operations

Compensating Controls:
1. Implement strict input validation and path canonicalization at the application layer
2. Deploy file integrity monitoring (FIM) on sensitive directories to detect unauthorized access attempts
3. Apply principle of least privilege - run OpenHarness with minimal required permissions
4. Enable comprehensive audit logging for all file access operations
5. Implement Web Application Firewall (WAF) rules to detect path traversal patterns

Detection Rules:
1. Monitor for grep/glob commands with path parameters containing '../' or absolute paths to sensitive directories
2. Alert on access attempts to /etc, /root, /var/lib/secrets, or other sensitive system directories
3. Track failed permission checks followed by successful file reads
4. Monitor for unusual process execution patterns from OpenHarness service accounts

Patching:
1. Monitor OpenHarness GitHub repository for commit bd4df81 or later releases
2. Prepare upgrade plan and test in non-production environment immediately upon patch availability
3. Prioritize patching for systems with internet-facing OpenHarness instances
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع نشرات OpenHarness لتحديد الحالات ونطاق وصولها
2. مراجعة سجلات الوصول للتحقق من استدعاءات أدوات grep/glob المريبة مع معاملات المسار غير العادية
3. تنفيذ تقسيم الشبكة لتقييد وصول OpenHarness إلى الشبكات الموثوقة فقط
4. تعطيل أو تقييد الوصول إلى أدوات grep و glob المدمجة إذا لم تكن ضرورية للعمليات

الضوابط التعويضية:
1. تنفيذ التحقق الصارم من المدخلات وتطبيع المسارات على مستوى التطبيق
2. نشر مراقبة سلامة الملفات (FIM) على الدلائل الحساسة للكشف عن محاولات الوصول غير المصرح به
3. تطبيق مبدأ أقل امتياز - تشغيل OpenHarness بأقل صلاحيات مطلوبة
4. تفعيل تسجيل التدقيق الشامل لجميع عمليات الوصول إلى الملفات
5. تنفيذ قواعد جدار الحماية لتطبيقات الويب (WAF) للكشف عن أنماط اجتياز المسارات

قواعد الكشف:
1. مراقبة أوامر grep/glob مع معاملات المسار التي تحتوي على '../' أو المسارات المطلقة للدلائل الحساسة
2. تنبيهات محاولات الوصول إلى /etc و /root و /var/lib/secrets أو دلائل النظام الحساسة الأخرى
3. تتبع فحوصات الأذونات الفاشلة متبوعة بقراءات ملفات ناجحة
4. مراقبة أنماط تنفيذ العمليات غير العادية من حسابات خدمة OpenHarness

التصحيح:
1. مراقبة مستودع OpenHarness على GitHub للالتزام bd4df81 أو الإصدارات الأحدث
2. إعداد خطة الترقية واختبارها في بيئة غير الإنتاج فوراً عند توفر التصحيح
3. أولويات التصحيح للأنظمة التي تحتوي على نشرات OpenHarness المواجهة للإنترنت
