📄 Description (English)
Exposure of sensitive information to an unauthorized actor in Windows Remote Procedure Call allows an authorized attacker to disclose information locally.
🤖 AI Executive Summary
CVE-2026-32085 is a medium-severity information disclosure vulnerability in Windows RPC that allows authorized local attackers to access sensitive information. While currently unpatched and without public exploits, the vulnerability poses a risk to organizations relying on Windows-based infrastructure for critical operations. Saudi organizations should monitor for patches and implement compensating controls to restrict local access.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily affects Saudi organizations with Windows-based infrastructure, particularly in banking (SAMA-regulated institutions), government agencies (NCA oversight), healthcare systems, and telecommunications providers. The local-only attack vector limits immediate risk, but insider threats and compromised accounts pose significant concerns. Organizations managing critical infrastructure through Windows RPC services face elevated risk of unauthorized information disclosure.

🔧 Remediation Steps (English)
Immediate Actions:
1. Inventory all Windows systems utilizing RPC services across your organization
2. Restrict local access to RPC services through Group Policy and NTFS permissions
3. Implement principle of least privilege for user accounts and service accounts
4. Enable Windows Event Logging for RPC activities (Event ID 5156, 5157)
5. Monitor for suspicious local access patterns to RPC endpoints
Compensating Controls:
6. Implement application whitelisting to restrict RPC client execution
7. Use Windows Defender Application Guard for sensitive workstations
8. Deploy endpoint detection and response (EDR) solutions to detect unauthorized RPC access
9. Segment networks to isolate critical systems from general user access
10. Conduct access reviews for service accounts with RPC permissions
Detection Rules:
- Monitor for RPC calls from unexpected processes using Sysmon Event ID 3 (Network Connection)
- Alert on failed RPC authentication attempts (Event ID 5805)
- Track modifications to RPC registry keys (HKLM\Software\Microsoft\RPC)
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع أنظمة Windows التي تستخدم خدمات RPC في مؤسستك
2. قيد الوصول المحلي إلى خدمات RPC من خلال Group Policy وأذونات NTFS
3. طبق مبدأ الحد الأدنى من الامتيازات لحسابات المستخدمين وحسابات الخدمة
4. فعّل تسجيل أحداث Windows لأنشطة RPC (معرف الحدث 5156، 5157)
5. راقب الأنماط المريبة للوصول المحلي إلى نقاط نهاية RPC
الضوابط التعويضية:
6. طبق قائمة بيضاء للتطبيقات لتقييد تنفيذ عملاء RPC
7. استخدم Windows Defender Application Guard لمحطات العمل الحساسة
8. نشّر حلول الكشف والاستجابة على نقاط النهاية (EDR)
9. قسّم الشبكات لعزل الأنظمة الحرجة عن الوصول العام
10. أجرِ مراجعات وصول لحسابات الخدمة التي لها أذونات RPC
قواعد الكشف:
- راقب استدعاءات RPC من عمليات غير متوقعة باستخدام Sysmon Event ID 3
- أصدر تنبيهات عند فشل محاولات مصادقة RPC (معرف الحدث 5805)
- تتبع التعديلات على مفاتيح سجل RPC
