🔧 Remediation Steps (English)
Immediately upgrade Totolink N300RH firmware to the latest patched version beyond 3.2.4-B20220812.

Replace affected devices with patched firmware versions.
🔧 خطوات المعالجة (العربية)
قم بترقية برنامج جهاز Totolik N300RH فورًا إلى أحدث إصدار مصحح بعد 3.2.4-B20220812. إذا لم يكن التصحيح الفوري متاحًا، قم بتعطيل الوصول البعيد إلى واجهة الويب للجهاز، وتطبيق تقسيم الشبكة لتقييد الوصول إلى واجهات إدارة الجهاز، ومراقبة طلبات POST المريبة. استبدل الأجهزة المتأثرة بإصدارات برنامج مصححة.
