📄 Description (English)
A weakness has been identified in Edimax EW-7438RPn 1.12. This affects the function formAccept of the file /goform/formAccep of the component POST Request Handler. This manipulation of the argument submit-url causes command injection. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
🤖 AI Executive Summary
CVE-2026-9361 is a command injection vulnerability in Edimax EW-7438RPn wireless router (firmware 1.12) affecting the POST request handler. An unauthenticated attacker can inject arbitrary commands via the submit-url parameter, potentially gaining remote code execution. With no patch available and public exploit disclosure, this poses an immediate risk to organizations using this router model in their network infrastructure.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily impacts Saudi organizations in telecommunications (STC, Mobily), government agencies, and enterprises using Edimax EW-7438RPn routers for network access points or branch office connectivity. Banking and financial institutions relying on these routers for secure network perimeters face elevated risk. Healthcare facilities and critical infrastructure operators using this equipment are at particular risk due to potential network compromise and lateral movement capabilities. The lack of vendor response and available patch significantly elevates risk for SAMA-regulated entities and NCA-monitored government networks.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Edimax EW-7438RPn devices running firmware 1.12 in your network using asset inventory and network scanning tools
2. Isolate affected devices from critical network segments if possible, or implement strict network access controls
3. Monitor for suspicious POST requests to /goform/formAccep endpoint with submit-url parameters
4. Implement Web Application Firewall (WAF) rules to block malicious submit-url payloads containing command injection patterns (;, |, &, $(), backticks)
PATCHING GUIDANCE:
1. Check Edimax support portal for firmware updates beyond 1.12 (though vendor non-responsiveness suggests limited availability)
2. If no official patch exists, plan device replacement with alternative vendors (TP-Link, Cisco, Ubiquiti)
3. Document all affected devices and establish replacement timeline
COMPENSATING CONTROLS:
1. Restrict administrative access to router management interfaces (disable remote management, limit to internal IPs only)
2. Implement network segmentation to limit router exposure
3. Deploy intrusion detection/prevention systems (IDS/IPS) with signatures for command injection attempts
4. Enable router logging and forward logs to SIEM for analysis
5. Implement rate limiting on /goform/formAccep endpoint
DETECTION RULES:
1. Alert on POST requests to /goform/formAccep containing special characters in submit-url parameter
2. Monitor for unusual process execution originating from router IP addresses
3. Track failed authentication attempts followed by POST requests to vulnerable endpoint
4. Detect outbound connections from router to external command and control servers
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع أجهزة Edimax EW-7438RPn التي تعمل بالإصدار 1.12 في شبكتك باستخدام أدوات جرد الأصول وفحص الشبكة
2. عزل الأجهزة المتأثرة عن قطاعات الشبكة الحرجة إن أمكن، أو تطبيق ضوابط وصول شبكة صارمة
3. مراقبة طلبات POST المريبة إلى نقطة نهاية /goform/formAccep مع معاملات submit-url
4. تطبيق قواعد جدار حماية تطبيقات الويب (WAF) لحجب حمولات حقن الأوامر الضارة
إرشادات التصحيح:
1. التحقق من بوابة دعم Edimax للحصول على تحديثات البرامج الثابتة بعد الإصدار 1.12
2. إذا لم يكن هناك تصحيح رسمي، خطط لاستبدال الجهاز بموردين بدلاء
3. توثيق جميع الأجهزة المتأثرة وإنشاء جدول زمني للاستبدال
الضوابط التعويضية:
1. تقييد الوصول الإداري إلى واجهات إدارة جهاز التوجيه
2. تطبيق تقسيم الشبكة لتحديد تعرض جهاز التوجيه
3. نشر أنظمة كشف/منع الاختراق (IDS/IPS) مع توقيعات لمحاولات حقن الأوامر
4. تفعيل تسجيل جهاز التوجيه وإعادة توجيه السجلات إلى SIEM
5. تطبيق تحديد معدل على نقطة نهاية /goform/formAccep
قواعد الكشف:
1. تنبيه على طلبات POST إلى /goform/formAccep تحتوي على أحرف خاصة في معامل submit-url
2. مراقبة تنفيذ العمليات غير العادية من عناوين IP لجهاز التوجيه
3. تتبع محاولات المصادقة الفاشلة متبوعة بطلبات POST إلى نقطة النهاية الضعيفة
4. كشف الاتصالات الصادرة من جهاز التوجيه إلى خوادم التحكم والقيادة الخارجية
