📄 Description (English)

A vulnerability was determined in TRENDnet TEW-713RE up to 1.02. The affected element is the function sub_421494 of the file /goform/addRouting. Executing a manipulation of the argument dest can lead to command injection. It is possible to launch the attack remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

🤖 AI Executive Summary

CVE-2026-5183 is a command injection vulnerability in TRENDnet TEW-713RE routers (up to version 1.02) affecting the routing configuration function. An attacker can remotely execute arbitrary commands by manipulating the 'dest' parameter in the /goform/addRouting endpoint. With no vendor patch available and public exploit disclosure, this poses an immediate risk to organizations using affected router models in their network infrastructure.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily impacts Saudi organizations using TRENDnet TEW-713RE routers as edge network devices. Most at-risk sectors include: (1) Banking and Financial Services (SAMA-regulated entities) using these routers for branch connectivity; (2) Government agencies and critical infrastructure operators relying on these devices for network segmentation; (3) Healthcare facilities using them for departmental network isolation; (4) Telecommunications providers (STC, Mobily, Zain) potentially using these in customer premises equipment or network infrastructure; (5) Energy sector organizations (ARAMCO subsidiaries) using them in operational technology networks. The lack of vendor response and public exploit availability significantly elevates risk for all affected deployments.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify and inventory all TRENDnet TEW-713RE devices in your network infrastructure
2. Isolate affected routers from internet-facing positions if possible, or implement strict network segmentation
3. Disable remote management access to the /goform/addRouting endpoint
4. Monitor router logs for suspicious routing configuration attempts

COMPENSATING CONTROLS (No patch available):
1. Implement Web Application Firewall (WAF) rules to block requests to /goform/addRouting containing special characters (;|&`$())
2. Restrict administrative access to router management interfaces using IP whitelisting
3. Deploy network-based intrusion detection signatures for command injection attempts targeting this endpoint
4. Implement strict input validation at network perimeter for any traffic destined to router management ports
5. Consider replacing affected devices with patched alternatives from TRENDnet or alternative vendors

DETECTION RULES:
1. Monitor HTTP POST requests to /goform/addRouting with dest parameter containing: semicolons, pipes, backticks, dollar signs, or parentheses
2. Alert on any successful routing table modifications from unexpected sources
3. Track failed authentication attempts to router management interfaces
4. Monitor for unusual process execution on router devices (if logging available)

LONG-TERM MITIGATION:
1. Evaluate replacement with newer TRENDnet models or alternative vendors with active security support
2. Implement network segmentation to limit router compromise impact
3. Deploy out-of-band management networks for router administration
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد وحصر جميع أجهزة TRENDnet TEW-713RE في البنية التحتية للشبكة
2. عزل أجهزة التوجيه المتأثرة عن المواضع المواجهة للإنترنت إن أمكن، أو تطبيق تقسيم شبكة صارم
3. تعطيل الوصول الإداري البعيد إلى نقطة نهاية /goform/addRouting
4. مراقبة سجلات جهاز التوجيه للمحاولات المريبة لتكوين التوجيه

الضوابط التعويضية (لا يوجد تصحيح متاح):
1. تطبيق قواعد جدار حماية تطبيقات الويب (WAF) لحظر الطلبات إلى /goform/addRouting التي تحتوي على أحرف خاصة (;|&`$())
2. تقييد الوصول الإداري إلى واجهات إدارة جهاز التوجيه باستخدام القائمة البيضاء للعناوين
3. نشر توقيعات كشف الاختراق القائمة على الشبكة لمحاولات حقن الأوامر التي تستهدف هذه النقطة النهائية
4. تطبيق التحقق الصارم من صحة المدخلات على محيط الشبكة لأي حركة مرور موجهة إلى منافذ إدارة جهاز التوجيه
5. النظر في استبدال الأجهزة المتأثرة ببدائل معدلة من TRENDnet أو بائعين بدائل

قواعد الكشف:
1. مراقبة طلبات HTTP POST إلى /goform/addRouting مع معامل dest يحتوي على: فواصل منقوطة أو أنابيب أو علامات اقتباس عكسية أو علامات دولار أو أقواس
2. التنبيه على أي تعديلات ناجحة لجدول التوجيه من مصادر غير متوقعة
3. تتبع محاولات المصادقة الفاشلة على واجهات إدارة جهاز التوجيه
4. مراقبة تنفيذ العمليات غير العادية على أجهزة التوجيه (إن توفر السجلات)

التخفيف على المدى الطويل:
1. تقييم الاستبدال بنماذج TRENDnet الأحدث أو بائعين بدائل مع دعم أمان نشط
2. تطبيق تقسيم الشبكة لتحديد تأثير اختراق جهاز التوجيه
3. نشر شبكات إدارة خارج النطاق لإدارة جهاز التوجيه
