📄 Description (English)
A vulnerability was identified in D-Link DIR-605L 2.13B01. Impacted is the function formSetLog of the file /goform/formSetLog of the component POST Request Handler. The manipulation of the argument curTime leads to buffer overflow. The attack is possible to be carried out remotely. The exploit is publicly available and might be used. This vulnerability only affects products that are no longer supported by the maintainer.
🤖 AI Executive Summary
A critical buffer overflow vulnerability exists in D-Link DIR-605L 2.13B01 routers affecting the /goform/formSetLog endpoint. The vulnerability allows remote attackers to execute arbitrary code by manipulating the curTime parameter in POST requests. Since this product is end-of-life with no patch available, organizations must implement immediate network segmentation and monitoring controls.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi organizations using legacy D-Link DIR-605L routers, particularly in: (1) Banking sector (SAMA-regulated institutions) using these devices for branch connectivity or backup internet access; (2) Government agencies (NCA oversight) with legacy network infrastructure; (3) Healthcare facilities relying on these routers for network access; (4) Small-to-medium enterprises and retail operations across Saudi Arabia. The end-of-life status makes this particularly dangerous as no vendor support is available. Remote code execution capability could lead to complete network compromise, data exfiltration, and lateral movement within organizational networks.
🏢 Affected Saudi Sectors
Banking and Financial Services (SAMA-regulated)
Government and Public Administration (NCA oversight)
Healthcare and Medical Facilities
Telecommunications (STC, Mobily, Zain)
Energy and Utilities (ARAMCO, SEC)
Retail and E-commerce
Small and Medium Enterprises (SMEs)

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify and inventory all D-Link DIR-605L 2.13B01 devices in your network using network scanning tools
2. Isolate affected devices from critical network segments immediately
3. Implement network segmentation: place routers in DMZ or restricted VLAN with minimal trust relationships
4. Disable remote management features (web interface access from WAN)
5. Restrict access to /goform/formSetLog endpoint at firewall level
PATCHING GUIDANCE:
- No patch is available from D-Link; device is end-of-life
- Plan immediate replacement with supported D-Link models or alternative vendors
- Establish replacement timeline within 30 days for critical infrastructure
COMPENSATING CONTROLS:
1. Deploy Web Application Firewall (WAF) rules to block POST requests to /goform/formSetLog
2. Implement IDS/IPS signatures to detect buffer overflow attempts in curTime parameter
3. Monitor router logs for suspicious POST requests to /goform endpoints
4. Implement network access controls (NAC) to restrict device connectivity
5. Deploy packet inspection to detect malicious payloads in POST data
DETECTION RULES:
- Alert on POST requests to /goform/formSetLog with curTime parameter exceeding 256 bytes
- Monitor for unusual process execution on router (if accessible via SSH)
- Track failed authentication attempts to router management interface
- Alert on unexpected outbound connections from router IP addresses
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد وحصر جميع أجهزة D-Link DIR-605L 2.13B01 في شبكتك باستخدام أدوات المسح
2. عزل الأجهزة المتأثرة عن قطاعات الشبكة الحرجة فوراً
3. تنفيذ تقسيم الشبكة: ضع أجهزة التوجيه في DMZ أو VLAN مقيد
4. تعطيل ميزات الإدارة البعيدة (الوصول إلى واجهة الويب من WAN)
5. تقييد الوصول إلى نقطة النهاية /goform/formSetLog على مستوى جدار الحماية
إرشادات التصحيح:
- لا توجد تصحيحات متاحة من D-Link؛ المنتج انتهت صلاحيته
- خطط لاستبدال فوري بنماذج D-Link مدعومة أو بدائل أخرى
- حدد جدول زمني للاستبدال خلال 30 يوماً للبنية التحتية الحرجة
عناصر التحكم البديلة:
1. نشر قواعد جدار تطبيقات الويب (WAF) لحظر طلبات POST إلى /goform/formSetLog
2. تنفيذ توقيعات IDS/IPS للكشف عن محاولات تجاوز المخزن المؤقت في معامل curTime
3. مراقبة سجلات جهاز التوجيه للطلبات المريبة إلى نقاط نهاية /goform
4. تنفيذ عناصر تحكم الوصول إلى الشبكة (NAC) لتقييد اتصال الجهاز
5. نشر فحص الحزم للكشف عن الحمولات الضارة في بيانات POST
قواعد الكشف:
- تنبيه على طلبات POST إلى /goform/formSetLog مع معامل curTime يتجاوز 256 بايت
- مراقبة تنفيذ العمليات غير العادية على جهاز التوجيه
- تتبع محاولات المصادقة الفاشلة على واجهة إدارة جهاز التوجيه
- تنبيه على الاتصالات الخارجية غير المتوقعة من عناوين IP لجهاز التوجيه
