📄 Description (English)
NETGEAR Multiple Routers Remote Code Execution Vulnerability — NETGEAR confirmed multiple routers allow unauthenticated web pages to pass form input directly to the command-line interface, permitting remote code execution.
🤖 AI Executive Summary
CVE-2016-6277 is a critical remote code execution vulnerability in multiple NETGEAR routers that allows unauthenticated attackers to execute arbitrary commands via crafted web requests. The vulnerability exists because web pages pass form input directly to the command-line interface without proper sanitization. With a CVSS score of 9.0 and publicly available exploits, this vulnerability poses an immediate threat to any organization using affected NETGEAR devices. This vulnerability has been actively exploited in the wild and was added to CISA's Known Exploited Vulnerabilities catalog.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability impacts Saudi organizations across multiple sectors that deploy NETGEAR routers in their network infrastructure. Small and medium enterprises, government branch offices, and telecom providers using NETGEAR equipment for edge connectivity are particularly at risk. Saudi banking institutions regulated by SAMA, government entities under NCA oversight, and energy sector organizations including ARAMCO contractors may have NETGEAR devices in remote offices or operational technology networks. Successful exploitation grants full device control, enabling attackers to intercept traffic, pivot into internal networks, modify DNS settings for phishing campaigns, or establish persistent backdoors within Saudi critical infrastructure.

🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all NETGEAR routers in your network inventory immediately
2. Disable remote management/administration interfaces on all affected devices
3. Restrict access to the router's web management interface to trusted internal IPs only
Patching Guidance:
4. Update firmware on all affected NETGEAR routers to the latest available version from https://www.netgear.com/support/
5. Affected models include R6250, R6400, R6700, R6900, R7000, R7100LG, R7300DST, R7900, R8000, D6220, D6400 — verify your model and apply the corresponding firmware update
6. If firmware updates are not available for your model, consider replacing the device with a supported model
Compensating Controls:
7. Place affected routers behind a firewall that blocks external access to management interfaces
8. Implement network segmentation to limit lateral movement from compromised devices
9. Deploy IDS/IPS rules to detect command injection patterns targeting NETGEAR devices
Detection Rules:
10. Monitor for HTTP requests containing command injection patterns (e.g., semicolons, pipe characters, backticks) targeting NETGEAR web interfaces
11. Alert on unusual outbound connections from router management IPs
12. Search logs for access to /cgi-bin/ paths with suspicious parameters on NETGEAR devices
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع أجهزة توجيه NETGEAR في شبكتك فوراً
2. قم بتعطيل واجهات الإدارة عن بُعد على جميع الأجهزة المتأثرة
3. قيّد الوصول إلى واجهة إدارة الويب للموجه على عناوين IP الداخلية الموثوقة فقط
إرشادات التصحيح:
4. قم بتحديث البرنامج الثابت على جميع أجهزة توجيه NETGEAR المتأثرة إلى أحدث إصدار متاح من https://www.netgear.com/support/
5. تشمل الطرازات المتأثرة R6250 وR6400 وR6700 وR6900 وR7000 وR7100LG وR7300DST وR7900 وR8000 وD6220 وD6400 — تحقق من طرازك وطبّق تحديث البرنامج الثابت المناسب
6. إذا لم تتوفر تحديثات البرنامج الثابت لطرازك، فكر في استبدال الجهاز بطراز مدعوم
الضوابط التعويضية:
7. ضع أجهزة التوجيه المتأثرة خلف جدار حماية يمنع الوصول الخارجي لواجهات الإدارة
8. طبّق تجزئة الشبكة للحد من الحركة الجانبية من الأجهزة المخترقة
9. انشر قواعد IDS/IPS للكشف عن أنماط حقن الأوامر التي تستهدف أجهزة NETGEAR
قواعد الكشف:
10. راقب طلبات HTTP التي تحتوي على أنماط حقن الأوامر التي تستهدف واجهات ويب NETGEAR
11. أنشئ تنبيهات للاتصالات الصادرة غير المعتادة من عناوين IP لإدارة أجهزة التوجيه
12. ابحث في السجلات عن الوصول إلى مسارات /cgi-bin/ مع معلمات مشبوهة على أجهزة NETGEAR
