📄 Description (English)

A security flaw has been discovered in Tenda F456 1.0.0.5. The impacted element is the function fromSetIpBind of the file /goform/SetIpBind of the component httpd. The manipulation of the argument page results in buffer overflow. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks.

🤖 AI Executive Summary

CVE-2026-7078 is a critical remote buffer overflow vulnerability in Tenda F456 router firmware (version 1.0.0.5) affecting the httpd service. The vulnerability exists in the SetIpBind function and can be exploited remotely without authentication to achieve arbitrary code execution. With a CVSS score of 8.8 and public exploit availability, this poses an immediate threat to organizations using this router model.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi organizations, particularly: (1) Banking sector - if Tenda F456 routers are used in branch networks or as edge devices; (2) Government agencies and NCA-regulated entities using these routers for network infrastructure; (3) Telecom providers (STC, Mobily, Zain) managing customer-facing network equipment; (4) Healthcare facilities using these routers for medical device networks; (5) Energy sector including ARAMCO subsidiaries. The vulnerability enables complete device compromise, potential lateral movement into internal networks, and data exfiltration. Given the router's consumer/SMB positioning, widespread deployment in Saudi organizations is likely.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Tenda F456 devices in your network using network scanning tools (nmap, Shodan queries for Saudi IP ranges)
2. Isolate affected devices from critical network segments if possible
3. Implement network-level access controls to restrict access to the httpd service (port 80/443)
4. Monitor for exploitation attempts using IDS/IPS signatures

PATCHING GUIDANCE:
1. Check Tenda's official support portal for firmware updates beyond version 1.0.0.5
2. If no patch available, consider device replacement with alternative vendors
3. If replacement not feasible, implement compensating controls

COMPENSATING CONTROLS:
1. Deploy WAF rules to block requests to /goform/SetIpBind endpoint
2. Restrict administrative access to router management interfaces via IP whitelisting
3. Implement network segmentation to limit router access to authorized personnel only
4. Enable logging and monitoring on all router access attempts
5. Consider placing affected routers behind a reverse proxy with input validation

DETECTION RULES:
1. Monitor for HTTP POST requests to /goform/SetIpBind with oversized 'page' parameter
2. Alert on any successful authentication to router management interface from unexpected sources
3. Track firmware version changes on affected devices
4. Monitor for unusual process execution on router (if accessible via SSH)
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع أجهزة Tenda F456 في شبكتك باستخدام أدوات المسح (nmap، استعلامات Shodan للنطاقات السعودية)
2. عزل الأجهزة المتأثرة عن القطاعات الحرجة في الشبكة إن أمكن
3. تطبيق عناصر تحكم الوصول على مستوى الشبكة لتقييد الوصول إلى خدمة httpd (المنفذ 80/443)
4. مراقبة محاولات الاستغلال باستخدام توقيعات IDS/IPS

إرشادات التصحيح:
1. تحقق من بوابة دعم Tenda الرسمية للحصول على تحديثات البرامج الثابتة بعد الإصدار 1.0.0.5
2. إذا لم يكن هناك تصحيح متاح، فكر في استبدال الجهاز بموردين بدلاء
3. إذا لم يكن الاستبدال ممكناً، قم بتطبيق عناصر تحكم تعويضية

عناصر التحكم التعويضية:
1. نشر قواعد WAF لحظر الطلبات إلى نقطة نهاية /goform/SetIpBind
2. تقييد الوصول الإداري إلى واجهات إدارة جهاز التوجيه عبر القائمة البيضاء للعناوين
3. تطبيق تقسيم الشبكة لتحديد وصول جهاز التوجيه للموظفين المصرح لهم فقط
4. تفعيل التسجيل والمراقبة لجميع محاولات الوصول إلى جهاز التوجيه
5. فكر في وضع الأجهزة المتأثرة خلف وكيل عكسي مع التحقق من صحة الإدخال

قواعد الكشف:
1. مراقبة طلبات HTTP POST إلى /goform/SetIpBind مع معامل 'page' كبير الحجم
2. تنبيه عند أي مصادقة ناجحة لواجهة إدارة جهاز التوجيه من مصادر غير متوقعة
3. تتبع تغييرات إصدار البرامج الثابتة على الأجهزة المتأثرة
4. مراقبة تنفيذ العمليات غير العادية على جهاز التوجيه (إذا كان يمكن الوصول إليه عبر SSH)
