📄 Description (English)

Microsoft Internet Explorer — CVE-2010-0249
Microsoft Internet Explorer contains an use-after-free vulnerability that could allow remote attackers to execute arbitrary code by accessing a pointer associated with a deleted object. The impacted product could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.

Required Action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Due Date: 2026-06-03

🤖 AI Executive Summary

CVE-2010-0249 is a critical use-after-free vulnerability in Microsoft Internet Explorer (CVSS 9.8) that enables remote code execution through malicious web content. This 14-year-old vulnerability affects end-of-life IE versions with no available patches, making it a legacy risk for organizations still running unsupported browsers. Immediate discontinuation of IE or implementation of compensating controls is essential for Saudi organizations.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: May 21, 2026 04:18
🇸🇦 Saudi Arabia Impact Assessment
Saudi banking sector (SAMA-regulated institutions) faces significant risk if legacy IE remains in use for online banking portals or internal systems. Government agencies under NCA oversight using IE for citizen services or internal operations are vulnerable. Healthcare organizations (MOH) and critical infrastructure operators (ARAMCO, SEC) relying on IE-dependent legacy applications face potential compromise. Telecom operators (STC, Mobily) with IE-based management interfaces are at risk. The impact is severe given the critical CVSS score and lack of patches.

🔧 Remediation Steps (English)
Immediate Actions:
1. Conduct inventory of all systems running Internet Explorer (any version) across the organization
2. Discontinue use of Internet Explorer immediately — migrate all users to modern browsers (Chrome, Firefox, Edge Chromium)
3. For legacy applications requiring IE: isolate systems on air-gapped networks or implement network segmentation

Patching Guidance:
- No patches available for this EOL vulnerability
- Vendor (Microsoft) recommends discontinuation of IE usage

Compensating Controls:
1. Deploy web content filtering to block known malicious sites
2. Implement application whitelisting on systems that cannot migrate
3. Use Group Policy to disable IE or restrict its functionality
4. Deploy endpoint detection and response (EDR) solutions to detect exploitation attempts
5. Implement network-based intrusion detection signatures for use-after-free exploitation patterns
6. Restrict IE access to trusted internal sites only via proxy/firewall rules
7. Disable JavaScript execution in IE if absolutely required for legacy apps

Detection Rules:
- Monitor for IE process crashes or unexpected memory access violations
- Alert on IE accessing deleted object pointers (requires memory forensics)
- Track IE process spawning cmd.exe or powershell.exe (code execution indicator)
- Monitor for unusual network connections initiated from IE process
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. إجراء جرد شامل لجميع الأنظمة التي تعمل بمتصفح Internet Explorer
2. التوقف الفوري عن استخدام Internet Explorer والانتقال إلى متصفحات حديثة (Chrome, Firefox, Edge)
3. للتطبيقات القديمة التي تتطلب IE: عزل الأنظمة على شبكات منفصلة أو تطبيق تقسيم الشبكة

إرشادات التصحيح:
- لا توجد تصحيحات متاحة لهذه الثغرة القديمة
- توصي Microsoft بالتوقف عن استخدام IE

الضوابط التعويضية:
1. نشر تصفية محتوى الويب لحجب المواقع الضارة المعروفة
2. تطبيق قائمة التطبيقات المسموحة على الأنظمة التي لا يمكن ترقيتها
3. استخدام Group Policy لتعطيل IE أو تقييد وظائفه
4. نشر حلول كشف ومعالجة نقاط النهاية (EDR)
5. تطبيق قواعد كشف التسلل على مستوى الشبكة
6. تقييد وصول IE إلى المواقع الداخلية الموثوقة فقط
7. تعطيل تنفيذ JavaScript في IE إذا لزم الأمر للتطبيقات القديمة
