📄 Description (English)
A vulnerability was identified in TRENDnet TEW-713RE up to 1.02. The impacted element is an unknown function of the file /goform/setSysAdm. The manipulation of the argument admuser leads to command injection. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
🤖 AI Executive Summary
A command injection vulnerability exists in TRENDnet TEW-713RE wireless routers (up to version 1.02) affecting the /goform/setSysAdm endpoint. An unauthenticated attacker can inject arbitrary commands via the admuser parameter, potentially gaining remote code execution on affected devices. With no patch available and the vendor unresponsive, this poses an immediate risk to organizations using these routers in their network infrastructure.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily impacts Saudi organizations in the following sectors: (1) Government agencies and municipalities using TRENDnet routers for network access points; (2) Small to medium-sized enterprises (SMEs) and retail businesses relying on these budget-friendly routers; (3) Educational institutions (universities, schools) with distributed network infrastructure; (4) Healthcare facilities with remote office connectivity; (5) Telecom service providers (STC, Mobily, Zain) potentially using these devices in customer premises equipment (CPE) deployments. The lack of vendor response and patch availability makes this a persistent threat requiring immediate device replacement or network isolation strategies.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all TRENDnet TEW-713RE devices in your network using network scanning tools (Nmap, Shodan queries for 'TRENDnet')
2. Isolate affected devices from critical network segments and internet-facing positions
3. Disable remote management features on the device if accessible
4. Change default credentials immediately (admin/admin)
5. Restrict access to /goform/setSysAdm endpoint via firewall rules
COMPENSATING CONTROLS:
1. Implement network segmentation - place routers in DMZ or isolated VLAN
2. Deploy Web Application Firewall (WAF) rules to block requests containing command injection patterns (;, |, &, $(), backticks) to /goform/setSysAdm
3. Monitor for suspicious HTTP POST requests to /goform/setSysAdm with unusual admuser parameter values
4. Implement rate limiting on administrative endpoints
5. Enable logging and alerting for failed authentication attempts
LONG-TERM REMEDIATION:
1. Replace TRENDnet TEW-713RE devices with supported, actively maintained alternatives (TP-Link, ASUS, Cisco)
2. Implement network access control (NAC) to prevent unauthorized device connections
3. Deploy intrusion detection signatures for command injection attempts
DETECTION RULES:
- Monitor HTTP POST requests to /goform/setSysAdm containing: admuser parameter with values including: semicolons, pipes, ampersands, command substitution syntax ($(), backticks)
- Alert on any successful administrative changes from unexpected source IPs
- Track failed login attempts followed by POST requests to /goform/setSysAdm
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع أجهزة TRENDnet TEW-713RE في شبكتك باستخدام أدوات المسح (Nmap، استعلامات Shodan)
2. عزل الأجهزة المتأثرة عن القطاعات الحرجة والمواضع المواجهة للإنترنت
3. تعطيل ميزات الإدارة البعيدة إن أمكن
4. تغيير بيانات الاعتماد الافتراضية فوراً (admin/admin)
5. تقييد الوصول إلى نقطة النهاية /goform/setSysAdm عبر قواعد جدار الحماية
الضوابط التعويضية:
1. تنفيذ تقسيم الشبكة - ضع أجهزة التوجيه في DMZ أو VLAN معزول
2. نشر قواعد جدار تطبيقات الويب (WAF) لحظر الطلبات التي تحتوي على أنماط حقن الأوامر
3. مراقبة طلبات HTTP POST المريبة إلى /goform/setSysAdm
4. تنفيذ تحديد معدل على نقاط النهاية الإدارية
5. تفعيل التسجيل والتنبيهات لمحاولات المصادقة الفاشلة
العلاج طويل الأجل:
1. استبدال أجهزة TRENDnet TEW-713RE بدائل مدعومة وموثوقة
2. تنفيذ التحكم في الوصول إلى الشبكة (NAC)
3. نشر توقيعات كشف الاختراق لمحاولات حقن الأوامر
