🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all systems running Angry IP Scanner 3.5.3 on Linux through asset inventory and endpoint detection tools
2. Restrict access to Angry IP Scanner to trusted administrators only via file permissions and access controls
3. Disable or remove Angry IP Scanner 3.5.3 if not actively required for operations
Patching Guidance:
1. Upgrade to Angry IP Scanner version 3.5.4 or later when available
2. Monitor official Angry IP Scanner releases and security advisories for patches
3. Implement version control to prevent downgrade to vulnerable versions
Compensating Controls:
1. Implement application whitelisting to restrict execution of Angry IP Scanner
2. Use Linux AppArmor or SELinux profiles to restrict port selection field input handling
3. Monitor process crashes and application errors through SIEM/logging systems
4. Restrict local user access to systems running the scanner
5. Run Angry IP Scanner in isolated/sandboxed environments when possible
Detection Rules:
1. Monitor for Angry IP Scanner process crashes (segmentation faults) in syslog
2. Alert on unexpected termination of Angry IP Scanner processes
3. Log and monitor access to Angry IP Scanner configuration files and preferences
4. Implement file integrity monitoring on Angry IP Scanner installation directory
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع الأنظمة التي تقوم بتشغيل Angry IP Scanner 3.5.3 على Linux من خلال جرد الأصول وأدوات كشف نقاط النهاية
2. تقييد الوصول إلى Angry IP Scanner للمسؤولين الموثوقين فقط عبر أذونات الملفات والضوابط الوصول
3. تعطيل أو إزالة Angry IP Scanner 3.5.3 إذا لم تكن مطلوبة بنشاط للعمليات
إرشادات التصحيح:
1. الترقية إلى Angry IP Scanner الإصدار 3.5.4 أو أحدث عند توفره
2. مراقبة الإصدارات الرسمية لـ Angry IP Scanner والتنبيهات الأمنية للحصول على التصحيحات
3. تنفيذ التحكم في الإصدار لمنع الرجوع إلى الإصدارات الضعيفة
الضوابط البديلة:
