🏷️ Title

CVE-2026-40047 - Apache Camel Docling CLI Argument Injection

🧾 Executive Summary

ثغرة أمنية خطيرة من نوع حقن وسيطات الأوامر (Argument Injection) في مكون camel-docling الخاص بإطار عمل Apache Camel، تسمح لمهاجم بحقن وسيطات CLI غير مرغوب فيها وقيم مسارات متجاوزة (Path Traversal) إلى الأداة الخارجية docling.

تقع الثغرة في الصنف DoclingProducer حيث تقوم الدالة addCustomArguments بإلحاق قائمة الوسائط المخصصة CamelDoclingCustomArguments إلى أمر docling دون تحقق كافٍ. كان التحقق المعتمد على قائمة محظورة (Denylist) فقط مع فحص حرفي لـ ../، مما يسمح بتجاوز الوسائط غير المعروفة والمسارات المطلقة.

🔬 Technical Analysis

The weakness was assessed from an application-security and infrastructure-risk perspective. The core issue is classified as Argument Injection and was documented in a sanitized form suitable for public portfolio publication.

Apache Camel هو إطار تكامل قوي يستخدم على نطاق واسع في المؤسسات لربط الأنظمة المختلفة. مكون camel-docling يقوم باستدعاء الأداة الخارجية docling (أداة تحويل المستندات) عبر ProcessBuilder.

📊 Impact

• Loss of confidentiality, integrity, or availability depending on exposure and business context.
• Increased operational risk and potential regulatory exposure if sensitive data is processed.

🛠️ Remediation

الإصلاح يستبدل الـ Denylist بـ قائمة مسموح بها (Allowlist) صارمة:

• فقط الأعلام المعترف بها مسموح بها
• رفض الأعلام التي يديرها المنتج (--output, -o)
• رفض رموز shell الخاصة (دفاع في العمق)
• تطبيع المسارات عبر Path.normalize() قبل التحقق

🧠 Lessons Learned & Mitigation Strategy

• Treat every integration boundary as untrusted, especially when application logic forwards user-controlled values to filesystems, shells, parsers, or external tools.
• Security reviews should validate the complete exploit chain, not only the first vulnerable endpoint; low-severity misconfigurations can become critical when chained.
• Public-facing documentation should describe risk, root cause, and remediation without exposing operational identifiers, credentials, or reusable exploitation artifacts.
• Defensive controls should combine preventive validation, runtime least privilege, telemetry, and patch governance to reduce both exploitability and blast radius.

🧼 Publication Sanitization Notes

• Sensitive infrastructure identifiers, IP addresses, hostnames, credentials, hashes, and e-mail addresses were replaced with explicit placeholders.
• Reusable operational evidence was minimized or abstracted to keep the document suitable for public GitHub publication.
• The document uses a consultant-style structure aligned with common web security testing report practices such as OWASP WSTG reporting expectations.
