📄 Description (English)

Improper Control of Interaction Frequency vulnerability in MeWare Software Development Inc. PDKS allows Flooding.

This issue affects PDKS: from V16.20200313 before VMYR_3.5.2025117.

🤖 AI Executive Summary

CVE-2026-7402 is a high-severity improper interaction frequency control vulnerability in MeWare PDKS that enables flooding attacks. With a CVSS score of 8.1 and no patch currently available, this vulnerability poses significant risk to organizations using affected PDKS versions. The lack of exploit availability provides a limited window for remediation before potential weaponization.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: May 5, 2026 02:16
🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily impacts Saudi organizations using MeWare PDKS in critical infrastructure sectors. Government agencies (NCA, NCSC), banking institutions (SAMA-regulated), and telecommunications providers (STC, Mobily) utilizing PDKS for document processing or workflow management face elevated risk. The flooding vulnerability could enable denial-of-service attacks, disrupting critical operations. Energy sector organizations (ARAMCO, SEC) and healthcare providers using PDKS-based systems are also at risk of service disruption and potential data exposure.

/ 10.0
🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all systems running PDKS versions V16.20200313 through versions before VMYR_3.5.2025117
2. Isolate affected systems from critical network segments if possible
3. Implement network-level rate limiting and DDoS mitigation controls
4. Enable detailed logging of all PDKS interactions and API calls

Compensating Controls (until patch available):
5. Deploy Web Application Firewall (WAF) rules to detect and block flooding patterns
6. Implement connection throttling at network perimeter (limit requests per IP/session)
7. Configure PDKS timeout settings to minimum acceptable values
8. Monitor for unusual interaction frequency spikes in real-time
9. Establish incident response procedures for flooding attack scenarios

Patching Guidance:
10. Upgrade to VMYR_3.5.2025117 or later immediately upon release
11. Test patches in isolated environment before production deployment
12. Maintain backup systems during patching windows

Detection Rules:
13. Alert on requests exceeding 100 interactions per minute from single source
14. Monitor for connection reset patterns indicating resource exhaustion
15. Track PDKS error logs for rate-limit or timeout exceptions
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع الأنظمة التي تعمل بإصدارات PDKS من V16.20200313 إلى الإصدارات السابقة لـ VMYR_3.5.2025117
2. عزل الأنظمة المتأثرة عن قطاعات الشبكة الحرجة إن أمكن
3. تطبيق تحديد معدل على مستوى الشبكة وعناصر تخفيف هجمات DDoS
4. تفعيل تسجيل مفصل لجميع تفاعلات PDKS واستدعاءات API

عناصر التحكم البديلة (حتى توفر التصحيح):
5. نشر قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن أنماط الفيضان وحجبها
6. تطبيق تحديد الاتصالات على محيط الشبكة (تحديد الطلبات لكل IP/جلسة)
7. تكوين إعدادات انتظار PDKS للقيم الدنيا المقبولة
8. مراقبة ارتفاعات تكرار التفاعل غير العادية في الوقت الفعلي
9. إنشاء إجراءات الاستجابة للحوادث لسيناريوهات هجمات الفيضان

توجيهات التصحيح:
10. الترقية إلى VMYR_3.5.2025117 أو إصدار أحدث فوراً عند الإصدار
11. اختبار التصحيحات في بيئة معزولة قبل نشرها في الإنتاج
12. الحفاظ على أنظمة احتياطية أثناء نوافذ التصحيح

قواعد الكشف:
13. تنبيهات عند تجاوز 100 تفاعل في الدقيقة من مصدر واحد
14. مراقبة أنماط إعادة تعيين الاتصال التي تشير إلى استنزاف الموارد
15. تتبع سجلات أخطاء PDKS لاستثناءات تحديد المعدل أو انتهاء المهلة الزمنية
