🤖 AI Executive Summary
CVE-2026-11408 is a remote OS command injection vulnerability in vertex-app's Log Viewer Endpoint affecting versions up to 2026.02.12. The vulnerability exists in the LogMod.js component where unsanitized query parameters allow attackers to execute arbitrary system commands. With a CVSS score of 6.3 and publicly available exploit code, this poses a moderate but exploitable risk to organizations running vulnerable versions.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily impacts Saudi organizations using vertex-app for logging and monitoring infrastructure. Government agencies (NCA, NCSC), financial institutions (SAMA-regulated banks), healthcare providers (MOH), and energy sector organizations (ARAMCO, SEC) running this application face direct risk of unauthorized command execution. The Log Viewer Endpoint exposure is particularly critical as logging systems are often trusted components with elevated privileges, potentially allowing lateral movement and data exfiltration across enterprise networks.

Government and Public Administration (NCA, NCSC, ministries)
Healthcare (MOH, private hospitals)
Energy and Utilities (ARAMCO, SEC, power distribution)

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all systems running vertex-app versions up to 2026.02.12 using asset inventory and vulnerability scanning
2. Isolate or restrict network access to Log Viewer Endpoint (typically port 8080 or custom ports) using WAF/firewall rules
3. Implement input validation rules blocking shell metacharacters (;|&$(){}[]<>\n) in req.query parameters
4. Enable comprehensive logging of all Log Viewer Endpoint requests for forensic analysis
PATCHING GUIDANCE:
1. Monitor vertex-app releases for patch availability beyond 2026.02.12
2. When patch becomes available, apply commit 805d82e7100d49b79b3beb1b9420e8e458987198 or later
3. Test patches in staging environment before production deployment
4. Maintain version control and rollback procedures
COMPENSATING CONTROLS (until patch available):
1. Deploy Web Application Firewall (WAF) rules to detect/block command injection patterns
2. Implement strict input validation: whitelist allowed characters, reject special shell characters
3. Run vertex-app with minimal privileges (non-root user account)
4. Use containerization with restricted syscall policies
5. Implement network segmentation restricting Log Viewer access to authorized IPs only
DETECTION RULES:
1. Monitor for req.query parameters containing: backticks, $(), |, ;, &, >, <, newlines
2. Alert on unusual process spawning from vertex-app process (node.js)
3. Monitor /proc/[pid]/cmdline for suspicious command patterns
4. Log all HTTP requests to /log or /viewer endpoints with full query strings
5. IDS signature: Look for patterns like `whoami`, `id`, `cat /etc/passwd` in HTTP parameters
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع الأنظمة التي تشغل vertex-app بإصدارات حتى 2026.02.12 باستخدام جرد الأصول والفحص الضعيف
2. عزل أو تقييد الوصول إلى نقطة نهاية عارض السجلات (عادة المنفذ 8080 أو المنافذ المخصصة) باستخدام قواعد WAF/جدار الحماية
3. تنفيذ قواعد التحقق من صحة الإدخال لحظر أحرف shell الخاصة (;|&$(){}[]<>\n) في معاملات req.query
4. تفعيل السجلات الشاملة لجميع طلبات نقطة نهاية عارض السجلات للتحليل الجنائي
إرشادات التصحيح:
1. مراقبة إصدارات vertex-app للحصول على توفر التصحيح بعد 2026.02.12
2. عند توفر التصحيح، تطبيق الالتزام 805d82e7100d49b79b3beb1b9420e8e458987198 أو أحدث
3. اختبار التصحيحات في بيئة التدريج قبل نشر الإنتاج
4. الحفاظ على التحكم في الإصدار وإجراءات الاسترجاع
الضوابط التعويضية (حتى توفر التصحيح):
1. نشر قواعد جدار تطبيقات الويب (WAF) للكشف عن أنماط حقن الأوامر أو حظرها
2. تنفيذ التحقق من صحة الإدخال الصارم: قائمة بيضاء للأحرف المسموحة، رفض أحرف shell الخاصة
3. تشغيل vertex-app بامتيازات دنيا (حساب مستخدم غير جذر)
4. استخدام الحاويات مع سياسات syscall مقيدة
5. تنفيذ تقسيم الشبكة يقيد وصول عارض السجلات إلى عناوين IP المصرح بها فقط
قواعد الكشف:
1. مراقبة معاملات req.query التي تحتوي على: علامات عكسية، $()، |، ;، &، >، <، أسطر جديدة
2. التنبيه على توليد العمليات غير المعتادة من عملية vertex-app (node.js)
3. مراقبة /proc/[pid]/cmdline للأنماط المريبة
4. تسجيل جميع طلبات HTTP إلى نقاط نهاية /log أو /viewer مع سلاسل الاستعلام الكاملة
5. توقيع IDS: البحث عن أنماط مثل `whoami`، `id`، `cat /etc/passwd` في معاملات HTTP
