📄 Description (English)

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) disclose sensitive account credentials in cleartext within HTTP responses generated by the maintenance interface. Because the management interface is accessible over unencrypted HTTP by default, credentials may be exposed to network-based interception.

🤖 AI Executive Summary

Tenda W30E V2 router firmware versions up to V16.01.0.19(5037) expose sensitive account credentials in cleartext through HTTP responses from the maintenance interface. The vulnerability allows network-based interception of credentials due to unencrypted HTTP transmission by default. This affects widely deployed consumer and SME routers across Saudi Arabia, creating significant risk for credential compromise and lateral network movement.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: May 4, 2026 14:16
🇸🇦 Saudi Arabia Impact Assessment
High impact for Saudi SMEs, government agencies, and residential users relying on Tenda routers for network access. Telecommunications sector (STC, Mobily) customers using these devices face credential exposure. Banking sector employees on compromised networks could experience lateral movement attacks. Healthcare facilities using Tenda routers for network infrastructure are at risk of HIPAA-equivalent compliance violations under GDPR-aligned Saudi data protection frameworks. Government entities using these devices for non-critical infrastructure face espionage and network reconnaissance risks.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Tenda W30E V2 devices in your network using network scanning tools (nmap, Shodan queries for Saudi IP ranges)
2. Isolate affected routers from critical network segments if patching cannot be completed immediately
3. Change all router administrative credentials immediately and document the change
4. Monitor network traffic for suspicious HTTP requests to router management interfaces

PATCHING GUIDANCE:
1. Download firmware version V16.01.0.20 or later from Tenda's official support portal
2. Access router management interface via HTTPS only (if available in patched version)
3. Perform factory reset before firmware upgrade to clear any cached credentials
4. Verify patch installation by checking firmware version in device settings

COMPENSATING CONTROLS (if patching delayed):
1. Implement network segmentation: restrict access to router management interface to authorized admin IPs only
2. Deploy firewall rules blocking HTTP port 80 access to router management interface
3. Enable HTTPS-only access if available in current firmware version
4. Implement network-based detection: monitor for HTTP GET/POST requests to router containing credential patterns

DETECTION RULES:
1. Monitor for HTTP traffic (port 80) to router IP addresses containing keywords: 'password', 'username', 'credential', 'auth'
2. Alert on cleartext transmission of base64-encoded strings matching credential patterns from router IPs
3. Implement IDS signatures detecting Tenda W30E maintenance interface requests
4. Log all HTTP requests to router management interfaces and review for credential exposure
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع أجهزة Tenda W30E V2 في شبكتك باستخدام أدوات المسح (nmap، استعلامات Shodan للنطاقات السعودية)
2. عزل أجهزة التوجيه المتأثرة عن القطاعات الحرجة إذا لم يكن يمكن إكمال التصحيح فوراً
3. تغيير جميع بيانات اعتماد المسؤول عن جهاز التوجيه فوراً وتوثيق التغيير
4. مراقبة حركة المرور على الشبكة للكشف عن طلبات HTTP المريبة لواجهات إدارة جهاز التوجيه

إرشادات التصحيح:
1. قم بتنزيل إصدار البرنامج الثابت V16.01.0.20 أو أحدث من بوابة دعم Tenda الرسمية
2. الوصول إلى واجهة إدارة جهاز التوجيه عبر HTTPS فقط (إن توفرت في الإصدار المصحح)
3. إجراء إعادة تعيين المصنع قبل ترقية البرنامج الثابت لمسح أي بيانات اعتماد مخزنة مؤقتاً
4. التحقق من تثبيت التصحيح بفحص إصدار البرنامج الثابت في إعدادات الجهاز

الضوابط البديلة (إذا تأخر التصحيح):
1. تنفيذ تقسيم الشبكة: تقييد الوصول إلى واجهة إدارة جهاز التوجيه لعناوين IP المسؤول المصرح بها فقط
2. نشر قواعد جدار الحماية لحظر وصول HTTP على المنفذ 80 إلى واجهة إدارة جهاز التوجيه
3. تفعيل الوصول عبر HTTPS فقط إذا كان متاحاً في إصدار البرنامج الثابت الحالي
4. تنفيذ الكشف القائم على الشبكة: مراقبة طلبات HTTP GET/POST إلى جهاز التوجيه التي تحتوي على أنماط بيانات الاعتماد

قواعد الكشف:
1. مراقبة حركة HTTP (المنفذ 80) لعناوين IP جهاز التوجيه التي تحتوي على كلمات رئيسية: 'كلمة المرور'، 'اسم المستخدم'، 'بيانات الاعتماد'، 'المصادقة'
2. تنبيه عند نقل السلاسل المشفرة بـ base64 التي تطابق أنماط بيانات الاعتماد من عناوين IP جهاز التوجيه
3. تنفيذ توقيعات IDS للكشف عن طلبات واجهة صيانة Tenda W30E
4. تسجيل جميع طلبات HTTP لواجهات إدارة جهاز التوجيه ومراجعتها للكشف عن تعرض بيانات الاعتماد
