📄 Description (English)
Endian Firewall version 3.3.25 and prior allow authenticated users to execute arbitrary OS commands via the DATE parameter to /cgi-bin/logs_firewall.cgi. The DATE parameter value is used to construct a file path that is passed to a Perl open() call, which allows command injection due to an incomplete regular expression validation.
🤖 AI Executive Summary
Endian Firewall versions 3.3.25 and prior contain a critical command injection vulnerability in the logs_firewall.cgi module that allows authenticated users to execute arbitrary OS commands via the DATE parameter. The vulnerability exploits incomplete regex validation in Perl's open() function, enabling attackers with valid credentials to gain full system compromise. This poses significant risk to Saudi organizations using Endian Firewall as perimeter security, particularly in banking and government sectors where firewall integrity is critical.

🇸🇦 Saudi Arabia Impact Assessment
High impact on Saudi banking sector (SAMA-regulated institutions) and government agencies (NCA oversight) that deploy Endian Firewall as perimeter security. Telecom operators (STC, Mobily) using Endian for network protection face risk of unauthorized access to network logs and potential lateral movement. Energy sector (ARAMCO, SEC) and healthcare organizations relying on Endian for security monitoring are vulnerable to command execution leading to data exfiltration and system compromise. The vulnerability requires authentication, limiting exposure to insider threats and compromised admin accounts, but the impact is severe given firewall's critical role in network defense.
🏢 Affected Saudi Sectors

⚖️ Saudi Risk Score (AI)

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Endian Firewall instances running version 3.3.25 or earlier in your environment
2. Restrict administrative access to firewall management interfaces using network segmentation and VPN
3. Implement strong authentication controls (MFA) for all firewall admin accounts
4. Monitor firewall logs for suspicious DATE parameter values containing shell metacharacters (|, ;, &, $, `, etc.)
PATCHING GUIDANCE:
1. Contact Endian support immediately for security updates or migration timeline
2. If no patch is available, plan upgrade to latest Endian Firewall version or alternative solution
3. Prioritize patching within 30 days given CVSS 8.8 and authentication requirement
COMPENSATING CONTROLS:
1. Implement Web Application Firewall (WAF) rules to block DATE parameters containing command injection patterns
2. Restrict access to /cgi-bin/logs_firewall.cgi to trusted IP ranges only
3. Disable remote management of firewall if not required; use local console access
4. Implement file integrity monitoring on firewall system binaries and configuration files
5. Enable comprehensive audit logging for all administrative actions
DETECTION RULES:
1. Alert on HTTP requests to /cgi-bin/logs_firewall.cgi with DATE parameter containing: pipe (|), semicolon (;), backtick (`), dollar sign ($), ampersand (&), newline characters
2. Monitor firewall process execution logs for unexpected child processes spawned from Perl interpreter
3. Alert on unusual file access patterns from firewall CGI processes
4. Correlate failed authentication attempts followed by successful admin logins within short timeframe
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع مثيلات Endian Firewall التي تعمل بالإصدار 3.3.25 أو أقدم في بيئتك
2. تقييد الوصول الإداري إلى واجهات إدارة جدار الحماية باستخدام تقسيم الشبكة وVPN
3. تنفيذ عناصر تحكم مصادقة قوية (MFA) لجميع حسابات مسؤول جدار الحماية
4. مراقبة سجلات جدار الحماية للقيم المريبة لمعامل DATE التي تحتوي على أحرف shell (|، ;، &، $، `، إلخ)
إرشادات التصحيح:
1. اتصل بدعم Endian فوراً للحصول على تحديثات أمان أو جدول زمني للترقية
2. إذا لم يكن هناك تصحيح متاح، خطط للترقية إلى أحدث إصدار من Endian Firewall أو حل بديل
3. أولويات التصحيح خلال 30 يوماً نظراً لـ CVSS 8.8 ومتطلبات المصادقة
عناصر التحكم التعويضية:
1. تنفيذ قواعد جدار تطبيقات الويب (WAF) لحظر معاملات DATE التي تحتوي على أنماط حقن الأوامر
2. تقييد الوصول إلى /cgi-bin/logs_firewall.cgi على نطاقات IP موثوقة فقط
3. تعطيل الإدارة البعيدة لجدار الحماية إذا لم تكن مطلوبة؛ استخدم الوصول إلى وحدة التحكم المحلية
4. تنفيذ مراقبة سلامة الملفات على ملفات نظام جدار الحماية والملفات الثنائية
5. تفعيل تسجيل التدقيق الشامل لجميع الإجراءات الإدارية
قواعد الكشف:
1. تنبيه على طلبات HTTP إلى /cgi-bin/logs_firewall.cgi مع معامل DATE يحتوي على: أنبوب (|)، فاصلة منقوطة (;)، علامة خلفية (`)، علامة دولار ($)، علامة العطف (&)، أحرف سطر جديد
2. مراقبة سجلات تنفيذ عملية جدار الحماية للعمليات الفرعية غير المتوقعة التي تم إطلاقها من مترجم Perl
3. تنبيه على أنماط الوصول إلى الملفات غير المعتادة من عمليات CGI لجدار الحماية
4. ربط محاولات المصادقة الفاشلة متبوعة بعمليات تسجيل دخول مسؤول ناجحة في إطار زمني قصير
