📄 Description (English)
Due to an uncontrolled resource consumption (Denial of Service) vulnerability, an authenticated attacker with regular user privileges and network access can repeatedly invoke a remote-enabled function module with an excessively large loop-control parameter. This triggers prolonged loop execution that consumes excessive system resources, potentially rendering the system unavailable. Successful exploitation results in a denial-of-service condition that impacts availability, while confidentiality and integrity remain unaffected.
🤖 AI Executive Summary
CVE-2026-23689 is a high-severity denial-of-service vulnerability in SAP Advanced Planning and Optimization (APO) and Supply Chain Management (SCM) modules affecting versions 700-714. An authenticated attacker can exploit uncontrolled resource consumption by invoking remote-enabled function modules with excessively large loop parameters, causing prolonged system unavailability. While no public exploit is currently available, the vulnerability requires immediate patching due to its impact on critical supply chain operations in Saudi organizations.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi organizations heavily dependent on SAP SCM/APO systems, particularly: (1) ARAMCO and energy sector companies relying on supply chain optimization for crude oil and petrochemical distribution; (2) Major retailers and FMCG distributors (e.g., Almarai, Jarir) using APO for demand planning; (3) Government procurement entities and military logistics operations; (4) Telecom operators (STC, Mobily, Zain) managing network equipment supply chains; (5) Healthcare sector supply chain for pharmaceutical and medical device distribution. Exploitation could disrupt critical supply chain visibility, demand forecasting, and inventory management, with cascading effects on national economic operations.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all SAP APO/SCM systems running versions 700-714 in your environment
2. Restrict network access to remote-enabled function modules to authorized users only
3. Implement IP whitelisting for SAP system access
4. Enable detailed logging for all function module invocations
PATCHING GUIDANCE:
1. Contact SAP support immediately to obtain security patches for affected versions
2. Schedule maintenance windows for patch deployment (prioritize production systems)
3. Test patches in non-production environments first
4. Apply patches in this order: SCM versions 700→701→702→712, then APO 713→714
COMPENSATING CONTROLS (if patch unavailable):
1. Implement SAP Gateway security policies to restrict function module access
2. Deploy resource consumption limits at the application server level
3. Configure work process timeout parameters to prevent prolonged loop execution
4. Use SAP Solution Manager to monitor function module execution times
DETECTION RULES:
1. Monitor for repeated invocations of remote-enabled modules with large parameter values
2. Alert on work processes consuming >80% CPU for >5 minutes
3. Track failed/timeout function module calls
4. Monitor SAP system logs (SM37, ST03) for unusual batch job patterns
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع أنظمة SAP APO/SCM التي تعمل بالإصدارات 700-714 في بيئتك
2. تقييد الوصول إلى وحدات الوظائف المفعلة عن بعد للمستخدمين المصرح لهم فقط
3. تطبيق قائمة بيضاء للعناوين IP لوصول نظام SAP
4. تفعيل السجلات التفصيلية لجميع استدعاءات وحدات الوظائف
إرشادات التصحيح:
1. التواصل مع دعم SAP فوراً للحصول على تصحيحات الأمان للإصدارات المتأثرة
2. جدولة نوافذ الصيانة لنشر التصحيحات (إعطاء الأولوية لأنظمة الإنتاج)
3. اختبار التصحيحات في بيئات غير الإنتاج أولاً
4. تطبيق التصحيحات بهذا الترتيب: SCM 700→701→702→712، ثم APO 713→714
الضوابط البديلة (إذا لم يكن التصحيح متاحاً):
1. تطبيق سياسات أمان SAP Gateway لتقييد وصول وحدات الوظائف
2. نشر حدود استهلاك الموارد على مستوى خادم التطبيق
3. تكوين معاملات انتظار عملية العمل لمنع تنفيذ الحلقة الطويلة
4. استخدام SAP Solution Manager لمراقبة أوقات تنفيذ وحدات الوظائف
قواعد الكشف:
1. مراقبة الاستدعاءات المتكررة للوحدات المفعلة عن بعد بقيم معاملات كبيرة
2. تنبيهات على عمليات العمل التي تستهلك >80% من وحدة المعالجة المركزية لمدة >5 دقائق
3. تتبع استدعاءات وحدات الوظائف الفاشلة/المنتهية
4. مراقبة سجلات نظام SAP (SM37, ST03) للأنماط غير العادية
