📄 Description (English)
A weakness has been identified in EFM ipTIME C200 up to 1.092. This vulnerability affects the function sub_408F90 of the file /cgi/iux_set.cgi of the component ApplyRestore Endpoint. This manipulation of the argument RestoreFile causes command injection. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
🤖 AI Executive Summary
CVE-2026-7833 is a critical command injection vulnerability in EFM ipTIME C200 routers (up to version 1.092) affecting the ApplyRestore endpoint. An unauthenticated attacker can execute arbitrary commands remotely by manipulating the RestoreFile parameter, potentially compromising network infrastructure. With no patch available and public exploit code circulating, this poses an immediate threat to organizations using affected devices.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi telecommunications infrastructure (STC, Mobily, Zain), government agencies (NCA, CITC), and financial institutions using ipTIME routers for network management. Banking sector (SAMA-regulated entities) faces critical risk if affected devices manage payment network segments. Energy sector (ARAMCO, SEC) and healthcare organizations using these routers for network access control are also at elevated risk. The lack of vendor response and public exploit availability increases likelihood of exploitation in Saudi networks.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify and inventory all EFM ipTIME C200 devices in your network (versions up to 1.092)
2. Isolate affected devices from critical network segments if possible
3. Implement network segmentation to restrict access to /cgi/iux_set.cgi endpoint
4. Monitor for suspicious RestoreFile parameter values in web server logs
COMPENSATING CONTROLS (until patch available):
5. Implement WAF rules to block requests to /cgi/iux_set.cgi containing command injection patterns (;, |, &, $(), backticks)
6. Restrict administrative access to ApplyRestore endpoint via IP whitelisting
7. Disable remote management features if not required
8. Implement strict input validation on all router configuration endpoints
DETECTION RULES:
9. Monitor for HTTP POST requests to /cgi/iux_set.cgi with RestoreFile parameter containing shell metacharacters
10. Alert on unexpected process execution from ipTIME router processes
11. Track failed and successful authentication attempts to management interfaces
PATCHING:
12. Contact EFM/ipTIME vendor for security updates or consider device replacement
13. Evaluate alternative router solutions with active security support
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد وحصر جميع أجهزة EFM ipTIME C200 في شبكتك (الإصدارات حتى 1.092)
2. عزل الأجهزة المتأثرة عن أجزاء الشبكة الحرجة إن أمكن
3. تطبيق تقسيم الشبكة لتقييد الوصول إلى نقطة نهاية /cgi/iux_set.cgi
4. مراقبة قيم معامل RestoreFile المريبة في سجلات خادم الويب
الضوابط البديلة (حتى توفر التصحيح):
5. تطبيق قواعد WAF لحظر الطلبات إلى /cgi/iux_set.cgi التي تحتوي على أنماط حقن الأوامر
6. تقييد الوصول الإداري إلى نقطة نهاية ApplyRestore عبر قائمة بيضاء للعناوين
7. تعطيل ميزات الإدارة البعيدة إذا لم تكن مطلوبة
8. تطبيق التحقق الصارم من صحة الإدخال على جميع نقاط نهاية تكوين الموجه
قواعد الكشف:
9. مراقبة طلبات HTTP POST إلى /cgi/iux_set.cgi مع معامل RestoreFile يحتوي على أحرف shell
10. التنبيه على تنفيذ العمليات غير المتوقعة من عمليات موجه ipTIME
11. تتبع محاولات المصادقة الفاشلة والناجحة لواجهات الإدارة
التصحيح:
12. الاتصال بمورد EFM/ipTIME للحصول على تحديثات أمان أو النظر في استبدال الجهاز
13. تقييم حلول الموجهات البديلة مع دعم أمان نشط
