📄 Description (English)

Acer ePowerSvc 6.0.3008.0 contains an unquoted service path vulnerability that allows local users to potentially execute code with elevated system privileges. Attackers can exploit the unquoted path in the service configuration to inject malicious code that would execute with LocalSystem permissions during service startup.

🤖 AI Executive Summary

CVE-2021-47823 is a privilege escalation vulnerability in Acer ePowerSvc 6.0.3008.0 exploiting an unquoted service path, allowing local attackers to execute arbitrary code with SYSTEM privileges. While no public exploit exists, the vulnerability is trivial to exploit and affects any system running the vulnerable Acer service management software. Organizations using Acer devices in their infrastructure face immediate risk of complete system compromise through local privilege escalation.

🔧 Remediation Steps (English)
1. IMMEDIATE: Identify all systems running Acer ePowerSvc 6.0.3008.0 using asset inventory and endpoint detection tools
2. PATCH: Upgrade Acer ePowerSvc to version 6.0.3009.0 or later immediately
3. COMPENSATING CONTROLS (if patching delayed): Restrict local administrative access, disable unnecessary services, implement application whitelisting to prevent unauthorized code execution
4. ACCESS CONTROL: Enforce principle of least privilege; audit and remove unnecessary local admin accounts
5. DETECTION: Monitor for suspicious service path modifications, unusual process execution from temp directories, and LocalSystem privilege escalation attempts
6. VALIDATION: After patching, verify service path is properly quoted in registry (HKLM\SYSTEM\CurrentControlSet\Services\ePowerSvc)
7. LOGGING: Enable Windows Event Log monitoring for service start failures and privilege escalation events
🔧 خطوات المعالجة (العربية)
1. فوري: تحديد جميع الأنظمة التي تقوم بتشغيل Acer ePowerSvc 6.0.3008.0 باستخدام أدوات جرد الأصول والكشف عن نقاط النهاية
2. تصحيح: ترقية Acer ePowerSvc إلى الإصدار 6.0.3009.0 أو أحدث على الفور
3. الضوابط التعويضية (إذا تأخر التصحيح): تقييد الوصول الإداري المحلي، تعطيل الخدمات غير الضرورية، تنفيذ القائمة البيضاء للتطبيقات
4. التحكم في الوصول: فرض مبدأ أقل امتياز؛ تدقيق وإزالة حسابات المسؤول المحلي غير الضرورية
5. الكشف: مراقبة التعديلات المريبة على مسار الخدمة، تنفيذ العمليات غير العادية من الدلائل المؤقتة، ومحاولات تصعيد امتيازات LocalSystem
6. التحقق: بعد التصحيح، تحقق من أن مسار الخدمة مقتبس بشكل صحيح في السجل
7. التسجيل: تفعيل مراقبة سجل أحداث Windows لفشل بدء الخدمة وأحداث تصعيد الامتيازات
