📄 Description (English)
Server-side request forgery (ssrf) in Azure Notification Service allows an authorized attacker to elevate privileges over a network.
🤖 AI Executive Summary
CVE-2026-41105 is a Server-Side Request Forgery (SSRF) vulnerability in Azure Notification Service with a CVSS score of 8.1 that allows authorized attackers to elevate privileges over a network. While no public exploit is currently available, the lack of a patch and the high severity rating present significant risk to organizations relying on Azure services. Immediate mitigation through network segmentation and access controls is critical for Saudi enterprises using Azure infrastructure.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi banking institutions (SAMA-regulated banks), government agencies (NCA oversight), and large enterprises using Azure Notification Service for critical communications. Financial services sector is particularly vulnerable as they rely heavily on Azure for customer notifications and transaction processing. Telecommunications providers (STC, Mobily) and healthcare organizations using Azure for patient notifications are also at elevated risk. The privilege escalation capability could lead to unauthorized access to sensitive customer data, transaction manipulation, and service disruption.

🔧 Remediation Steps (English)
Immediate Actions:
1. Audit all Azure Notification Service deployments and identify authorized users with access
2. Implement network segmentation to restrict Azure Notification Service communication to only required internal systems
3. Enable Azure Network Security Groups (NSGs) to limit outbound connections from the service
4. Review and restrict service principal permissions using Azure RBAC principle of least privilege
5. Monitor Azure activity logs for suspicious SSRF patterns (unusual outbound requests to internal IPs, metadata services)
Compensating Controls:
6. Implement Web Application Firewall (WAF) rules to detect and block SSRF attempts
7. Disable access to Azure Instance Metadata Service (IMDS) endpoints if not required
8. Use Azure Private Endpoints to restrict service communication to private networks
9. Enable Azure Defender for Cloud to detect anomalous behavior
10. Implement strict input validation on all parameters sent to Azure Notification Service
Detection Rules:
- Alert on requests from Azure Notification Service to internal IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)
- Monitor for requests to 169.254.169.254 (IMDS endpoint)
- Track unusual outbound connections from Azure Notification Service instances
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع نشرات خدمة Azure Notification Service وتحديد المستخدمين المصرحين بالوصول
2. تنفيذ تقسيم الشبكة لتقييد اتصالات Azure Notification Service بالأنظمة الداخلية المطلوبة فقط
3. تفعيل مجموعات أمان شبكة Azure (NSGs) لتحديد الاتصالات الصادرة من الخدمة
4. مراجعة وتقييد أذونات مبدأ الخدمة باستخدام Azure RBAC بمبدأ أقل امتياز
5. مراقبة سجلات نشاط Azure للكشف عن أنماط SSRF المريبة
الضوابط البديلة:
6. تنفيذ قواعد جدار الحماية لتطبيقات الويب (WAF) للكشف عن محاولات SSRF وحجبها
7. تعطيل الوصول إلى نقاط نهاية خدمة البيانات الوصفية لـ Azure إذا لم تكن مطلوبة
8. استخدام نقاط نهاية Azure الخاصة لتقييد اتصالات الخدمة بالشبكات الخاصة
9. تفعيل Azure Defender للسحابة للكشف عن السلوك الشاذ
10. تنفيذ التحقق الصارم من المدخلات على جميع المعاملات المرسلة إلى Azure Notification Service
