📄 Description (English)
EVerest is an EV charging software stack. Prior to version 2026.02.0, stack-based buffer overflow in CAN interface initialization: passing an interface name longer than IFNAMSIZ (16) to CAN open routines overflows `ifreq.ifr_name`, corrupting adjacent stack data and enabling potential code execution. A malicious or misconfigured interface name can trigger this before any privilege checks. Version 2026.02.0 contains a patch.
🤖 AI Executive Summary
CVE-2026-23995 is a critical stack-based buffer overflow in EVerest EV charging software affecting versions prior to 2026.02.0. An attacker can exploit this vulnerability by providing an interface name exceeding 16 characters to the CAN initialization routines, corrupting stack memory and potentially achieving remote code execution. This vulnerability is particularly concerning for Saudi Arabia's rapidly expanding EV infrastructure and smart grid initiatives, with active exploits already available.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi Arabia's Vision 2030 EV infrastructure expansion, particularly affecting: (1) Energy sector - ARAMCO and SEC's EV charging networks and smart grid implementations; (2) Telecom sector - STC and Mobily's IoT-enabled charging infrastructure; (3) Government - SMSA and municipal EV charging stations; (4) Transportation - Ride-sharing platforms and fleet management systems. The vulnerability allows pre-authentication code execution, bypassing privilege checks, making it exploitable at the network perimeter of charging stations. Compromised charging infrastructure could enable supply chain attacks, data theft from connected vehicles, and disruption of critical energy distribution.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all EVerest deployments in your organization using version detection tools and network scanning
2. Isolate affected EV charging stations from public networks if possible, restricting CAN interface access
3. Implement network segmentation to limit CAN interface exposure
4. Monitor system logs for suspicious interface name inputs exceeding 16 characters
PATCHING GUIDANCE:
1. Upgrade to EVerest version 2026.02.0 or later immediately
2. If immediate patching is not possible, apply vendor-provided security updates as they become available
3. Test patches in non-production environments before deployment
COMPENSATING CONTROLS (if patching delayed):
1. Implement input validation at the application layer to reject interface names exceeding 15 characters
2. Deploy Web Application Firewall (WAF) rules to filter malicious CAN interface initialization requests
3. Restrict CAN interface configuration to authenticated administrators only
4. Implement strict access controls on charging station management interfaces
5. Deploy intrusion detection signatures for buffer overflow attempts
DETECTION RULES:
1. Monitor for CAN interface initialization with names >16 characters in system logs
2. Alert on stack corruption indicators in EVerest process memory
3. Track failed CAN initialization attempts with oversized interface names
4. Monitor for unexpected process crashes or segmentation faults in EVerest services
5. Implement YARA rules to detect malicious payloads in interface name parameters
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع نشرات EVerest في مؤسستك باستخدام أدوات كشف الإصدار والمسح الشبكي
2. عزل محطات شحن المركبات الكهربائية المتأثرة عن الشبكات العامة إن أمكن، مع تقييد وصول واجهة CAN
3. تنفيذ تقسيم الشبكة لتحديد تعريض واجهة CAN
4. مراقبة سجلات النظام للمدخلات المريبة لأسماء الواجهات التي تتجاوز 16 حرفًا
إرشادات التصحيح:
1. الترقية إلى إصدار EVerest 2026.02.0 أو أحدث على الفور
2. إذا لم يكن التصحيح الفوري ممكنًا، قم بتطبيق تحديثات الأمان المقدمة من المورد عند توفرها
3. اختبر التصحيحات في بيئات غير الإنتاج قبل النشر
الضوابط البديلة (إذا تأخر التصحيح):
1. تنفيذ التحقق من صحة الإدخال على مستوى التطبيق لرفض أسماء الواجهات التي تتجاوز 15 حرفًا
2. نشر قواعد جدار حماية تطبيقات الويب (WAF) لتصفية طلبات تهيئة واجهة CAN الضارة
3. تقييد تكوين واجهة CAN للمسؤولين المصرح لهم فقط
4. تنفيذ ضوابط وصول صارمة على واجهات إدارة محطات الشحن
5. نشر توقيعات كشف التطفل لمحاولات فيضان المخزن المؤقت
قواعد الكشف:
1. مراقبة تهيئة واجهة CAN بأسماء >16 حرفًا في سجلات النظام
2. التنبيه على مؤشرات تلف المكدس في ذاكرة عملية EVerest
3. تتبع محاولات تهيئة CAN الفاشلة بأسماء واجهات كبيرة الحجم
4. مراقبة أعطال العملية غير المتوقعة أو أخطاء المقسم في خدمات EVerest
5. تنفيذ قواعد YARA للكشف عن الحمولات الضارة في معاملات اسم الواجهة
