📄 الوصف (الإنجليزية)
sheed AntiVirus 2.3 contains an unquoted service path vulnerability in the ShavProt service that allows local attackers to escalate privileges by exploiting the service binary path. Attackers can insert a malicious executable in the unquoted path and trigger service restart or system reboot to execute code with LocalSystem privileges.
🤖 ملخص AI
CVE-2016-20061 is a local privilege escalation vulnerability in Sheed AntiVirus 2.3 affecting the ShavProt service through an unquoted service path. Attackers with local access can place malicious executables in the service path to gain LocalSystem privileges upon service restart or system reboot. With no patch available and moderate exploit complexity, this poses a significant risk to organizations using this antivirus solution.

🔧 Remediation Steps (English)
Immediate Actions:
1. Inventory all systems running Sheed AntiVirus 2.3 and document deployment scope
2. Restrict local access to systems running the vulnerable antivirus through access controls and user privilege management
3. Monitor for suspicious file creation in service paths (typically C:\Program Files\Sheed or similar)
4. Implement application whitelisting to prevent unauthorized executable execution
Compensating Controls (No Patch Available):
1. Disable or remove Sheed AntiVirus 2.3 and migrate to alternative, actively maintained antivirus solutions
2. Apply principle of least privilege - ensure users operate with standard user accounts, not administrator
3. Implement file integrity monitoring on service directories
4. Enable Windows Service hardening and restrict service restart permissions
5. Deploy Host-based Intrusion Detection System (HIDS) to monitor suspicious process execution
Detection Rules:
1. Monitor for file creation in unquoted service paths with executable extensions (.exe, .dll, .sys)
2. Alert on ShavProt service restart or unexpected service state changes
3. Track process execution with LocalSystem privileges originating from service paths
4. Monitor registry changes to service configuration (HKLM\SYSTEM\CurrentControlSet\Services\ShavProt)
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع الأنظمة التي تعمل بـ Sheed AntiVirus 2.3 وتوثيق نطاق النشر
2. تقييد الوصول المحلي للأنظمة التي تعمل بمكافحة الفيروسات الضعيفة من خلال عناصر التحكم في الوصول وإدارة امتيازات المستخدم
3. مراقبة إنشاء الملفات المريبة في مسارات الخدمة
4. تنفيذ قائمة بيضاء للتطبيقات لمنع تنفيذ الملفات التنفيذية غير المصرح بها
عناصر التحكم التعويضية (لا يوجد تصحيح متاح):
1. تعطيل أو إزالة Sheed AntiVirus 2.3 والهجرة إلى حلول مكافحة فيروسات بديلة يتم صيانتها بنشاط
2. تطبيق مبدأ أقل امتياز - تأكد من أن المستخدمين يعملون بحسابات مستخدم قياسية وليس مسؤول
3. تنفيذ مراقبة سلامة الملفات على دلائل الخدمة
4. تفعيل تقسية خدمة Windows وتقييد أذونات إعادة تشغيل الخدمة
5. نشر نظام كشف الاختراق المستند إلى المضيف (HIDS) لمراقبة تنفيذ العملية المريبة
