📄 Description (English)

An insufficient authentication vulnerability in NETGEAR WiFi range
extenders allows a network adjacent attacker with WiFi authentication or
a physical Ethernet port connection to bypass the authentication
process and access the admin panel.

🤖 AI Executive Summary

CVE-2026-0407 is a critical authentication bypass vulnerability affecting NETGEAR WiFi range extenders (EX5000, EX3110, EX6110, EX2800) that allows network-adjacent attackers to access the admin panel without credentials. With a CVSS score of 8.0, this vulnerability poses significant risk to organizations using these devices for network extension, particularly in enterprise and government environments. Immediate patching is essential as the vulnerability requires only WiFi proximity or physical Ethernet access to exploit.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: Apr 26, 2026 16:03
🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi government agencies (NCA, GOSI), banking sector (SAMA-regulated institutions), healthcare facilities, and energy companies (ARAMCO) that deploy NETGEAR range extenders for network coverage. Government facilities and critical infrastructure using these devices for WiFi extension are particularly vulnerable to unauthorized administrative access, potentially leading to network compromise, data exfiltration, and lateral movement. Telecom operators (STC, Mobily) and enterprise networks using these extenders for coverage expansion face risks of network manipulation and service disruption.
🏢 Affected Saudi Sectors
Government (NCA, GOSI, Ministry of Interior) Banking and Financial Services (SAMA-regulated) Healthcare (MOH facilities) Energy (ARAMCO, power utilities) Telecommunications (STC, Mobily, Zain) Education (Universities, schools) Enterprise Networks

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all NETGEAR EX5000, EX3110, EX6110, and EX2800 devices in your network inventory
2. Isolate affected devices from critical network segments if patching cannot be completed immediately
3. Restrict physical access to Ethernet ports on affected devices
4. Review admin panel access logs for unauthorized access attempts

PATCHING GUIDANCE:
1. Download latest firmware from NETGEAR support portal for each affected model
2. Apply patches immediately following NETGEAR's firmware update procedures
3. Verify firmware version post-update to confirm successful patching
4. Test network connectivity and range extender functionality after patching

COMPENSATING CONTROLS (if immediate patching not possible):
1. Disable WiFi on affected devices and use only wired connections where possible
2. Implement network segmentation to isolate range extenders from critical systems
3. Deploy network access controls (NAC) to restrict unauthorized device access
4. Monitor for suspicious admin panel access attempts

DETECTION RULES:
1. Monitor for HTTP/HTTPS requests to range extender admin interfaces (typically port 80/443) from unexpected sources
2. Alert on successful admin panel logins without corresponding authentication requests
3. Track firmware version changes on affected devices
4. Monitor for configuration changes on range extenders outside maintenance windows
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع أجهزة NETGEAR EX5000 و EX3110 و EX6110 و EX2800 في جرد شبكتك
2. عزل الأجهزة المتأثرة عن أجزاء الشبكة الحرجة إذا لم يكن التصحيح ممكناً فوراً
3. قيد الوصول المادي إلى منافذ Ethernet على الأجهزة المتأثرة
4. راجع سجلات الوصول إلى لوحة التحكم للكشف عن محاولات الوصول غير المصرح بها

إرشادات التصحيح:
1. قم بتنزيل أحدث البرامج الثابتة من بوابة دعم NETGEAR لكل نموذج متأثر
2. طبق التصحيحات فوراً باتباع إجراءات تحديث البرامج الثابتة من NETGEAR
3. تحقق من إصدار البرنامج الثابت بعد التحديث لتأكيد التصحيح الناجح
4. اختبر اتصال الشبكة وعمل موسع النطاق بعد التصحيح

الضوابط البديلة (إذا لم يكن التصحيح الفوري ممكناً):
1. عطل WiFi على الأجهزة المتأثرة واستخدم الاتصالات السلكية فقط حيث أمكن
2. طبق تقسيم الشبكة لعزل موسعات النطاق عن الأنظمة الحرجة
3. نشر ضوابط الوصول إلى الشبكة (NAC) لتقييد الوصول غير المصرح به للأجهزة
4. راقب محاولات الوصول المريبة إلى لوحة التحكم

قواعد الكشف:
1. راقب طلبات HTTP/HTTPS إلى واجهات إدارة موسع النطاق (عادة المنفذ 80/443) من مصادر غير متوقعة
2. أصدر تنبيهات عند تسجيلات الدخول الناجحة إلى لوحة التحكم بدون طلبات مصادقة مقابلة
3. تتبع تغييرات إصدار البرنامج الثابت على الأجهزة المتأثرة
4. راقب تغييرات التكوين على موسعات النطاق خارج نوافذ الصيانة
