📄 Description (English)
A security flaw has been discovered in Edimax BR-6478AC 1.23. Affected by this issue is the function formiNICbasic of the file /goform/formiNICbasic of the component POST Request Handler. Performing a manipulation of the argument rootAPmac results in command injection. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
🤖 AI Executive Summary
CVE-2026-9441 is a command injection vulnerability in Edimax BR-6478AC wireless router (v1.23) affecting the POST request handler. An unauthenticated attacker can manipulate the rootAPmac parameter to execute arbitrary commands remotely. With a CVSS score of 6.3 and public exploit availability, this poses a significant risk to organizations using this router model, particularly in network infrastructure and remote access scenarios.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using Edimax BR-6478AC routers face significant risk, particularly: (1) Banking/SAMA-regulated entities using these devices in branch networks or remote access infrastructure; (2) Government agencies (NCA, NCSC) and critical infrastructure operators relying on these routers for network segmentation; (3) Telecommunications providers (STC, Mobily, Zain) using these devices in customer premises or network management; (4) Healthcare facilities using these routers for medical device connectivity; (5) Energy sector (ARAMCO, SEC) using these in SCADA/ICS environments. The lack of vendor response and public exploit availability elevates risk significantly.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Edimax BR-6478AC v1.23 devices in your network using network scanning tools (nmap, Shodan queries)
2. Isolate affected devices from critical networks if possible, or implement network segmentation
3. Disable remote management features on the router's web interface
4. Change default credentials and implement strong authentication
5. Monitor for suspicious POST requests to /goform/formiNICbasic endpoint
COMPENSATING CONTROLS (No patch available):
1. Implement WAF/IPS rules to block POST requests with suspicious rootAPmac parameters containing shell metacharacters (;|&$(){}[]<>)
2. Restrict access to router management interface via firewall rules (whitelist only authorized IPs)
3. Deploy network segmentation to isolate router management traffic
4. Enable logging and alerting on all POST requests to /goform/formiNICbasic
5. Consider replacing with alternative router models from vendors with active security support
DETECTION RULES:
- Monitor for POST requests to /goform/formiNICbasic with rootAPmac parameter containing: backticks, $(), semicolons, pipes, ampersands, or other shell metacharacters
- Alert on any successful command execution patterns in router logs
- Track failed authentication attempts to router management interface
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع أجهزة Edimax BR-6478AC v1.23 في شبكتك باستخدام أدوات المسح (nmap، استعلامات Shodan)
2. عزل الأجهزة المتأثرة عن الشبكات الحرجة إن أمكن، أو تطبيق تقسيم الشبكة
3. تعطيل ميزات الإدارة البعيدة على واجهة الويب للجهاز
4. تغيير بيانات الاعتماد الافتراضية وتطبيق المصادقة القوية
5. مراقبة طلبات POST المريبة إلى نقطة نهاية /goform/formiNICbasic
الضوابط التعويضية (لا يوجد تصحيح متاح):
1. تطبيق قواعد WAF/IPS لحظر طلبات POST بمعاملات rootAPmac مريبة تحتوي على أحرف shell (;|&$(){}[]<>)
2. تقييد الوصول إلى واجهة إدارة الجهاز عبر قواعد جدار الحماية (قائمة بيضاء للعناوين المصرح بها فقط)
3. نشر تقسيم الشبكة لعزل حركة إدارة الجهاز
4. تفعيل التسجيل والتنبيهات على جميع طلبات POST إلى /goform/formiNICbasic
5. النظر في استبدال أجهزة التوجيه ببدائل من البائعين الذين يتمتعون بدعم أمان نشط
