📄 Description (English)

A security vulnerability has been detected in decolua 9router up to 0.4.0. This issue affects the function isAuthenticated of the file src/dashboardGuard.js of the component HTTP Header Handler. The manipulation of the argument Host leads to improper authorization. The attack is possible to be carried out remotely. Upgrading to version 0.4.1 is capable of addressing this issue. The identifier of the patch is 428e2c045cb9c0eb8080e8b580471a9c2eaa95ca. Upgrading the affected component is recommended.

🤖 AI Executive Summary

CVE-2026-10269 is a medium-severity authorization bypass vulnerability in decolua 9router affecting the HTTP Header Handler's authentication mechanism. An attacker can manipulate the Host header to bypass authentication checks in the isAuthenticated function, potentially gaining unauthorized access to dashboard functionality. While no public exploit is currently available, the vulnerability is remotely exploitable and requires immediate patching to version 0.4.1 or later.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily impacts Saudi organizations using decolua 9router for API gateway or dashboard management, particularly in: Government agencies (NCA, CITC) using this component for administrative interfaces; Banking sector (SAMA-regulated institutions) if deployed in authentication infrastructure; Telecommunications providers (STC, Mobily, Zain) managing network administration dashboards; Healthcare organizations (MOH) using this for system administration. The authorization bypass could allow unauthorized access to sensitive administrative functions, configuration changes, and potential lateral movement within networks.

🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all instances of decolua 9router in your environment, particularly versions up to 0.4.0
2. Audit access logs for suspicious Host header manipulation patterns (e.g., unusual Host values, header injection attempts)
3. Implement WAF rules to validate Host header against whitelist of legitimate values
4. Enable detailed logging of authentication attempts and Host header values

Patching Guidance:
1. Upgrade decolua 9router to version 0.4.1 or later immediately
2. Apply patch 428e2c045cb9c0eb8080e8b580471a9c2eaa95ca if available
3. Test authentication functionality thoroughly after patching
4. Restart affected services to ensure patch is active

Compensating Controls (if patching delayed):
1. Implement reverse proxy authentication layer (nginx/Apache) with Host header validation
2. Restrict access to dashboard endpoints via IP whitelisting
3. Enforce mutual TLS (mTLS) for administrative access
4. Deploy network segmentation to limit dashboard access
5. Implement rate limiting on authentication endpoints

Detection Rules:
1. Monitor for Host header values that don't match expected domains
2. Alert on authentication bypass attempts (successful auth with invalid Host headers)
3. Track failed authentication attempts followed by successful access
4. Monitor for Host header injection patterns (special characters, multiple values)
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع نسخ decolua 9router في بيئتك، خاصة الإصدارات حتى 0.4.0
2. قم بمراجعة سجلات الوصول للبحث عن أنماط مريبة في التلاعب برأس Host
3. طبق قواعد WAF للتحقق من صحة رأس Host مقابل قائمة بيضاء
4. فعّل تسجيل مفصل لمحاولات المصادقة وقيم رأس Host

إرشادات التصحيح:
1. قم بترقية decolua 9router إلى الإصدار 0.4.1 أو أحدث فوراً
2. طبق التصحيح 428e2c045cb9c0eb8080e8b580471a9c2eaa95ca إن أمكن
3. اختبر وظائف المصادقة بعناية بعد التصحيح
4. أعد تشغيل الخدمات المتأثرة للتأكد من تفعيل التصحيح

الضوابط البديلة (إذا تأخر التصحيح):
1. طبق طبقة مصادقة reverse proxy مع التحقق من صحة رأس Host
2. قيّد الوصول إلى نقاط نهاية لوحة التحكم عبر قائمة بيضاء للعناوين
3. فرض TLS المتبادل (mTLS) للوصول الإداري
4. طبق تقسيم الشبكة لتحديد الوصول إلى لوحة التحكم
5. طبق تحديد معدل على نقاط نهاية المصادقة

قواعد الكشف:
1. راقب قيم رأس Host التي لا تطابق النطاقات المتوقعة
2. أصدر تنبيهات لمحاولات تجاوز المصادقة
3. تتبع محاولات المصادقة الفاشلة متبوعة بالوصول الناجح
4. راقب أنماط حقن رأس Host
