MikroTik Router OS Directory Traversal Vulnerability — MikroTik RouterOS through 6.42 allows unauthenticated remote attackers to read arbitrary files and remote authenticated attackers to write arbitrary files due to a directory traversal vulnerability in the WinBox interface.

🤖 AI Executive Summary

MikroTik RouterOS versions up to 6.42 contain a critical directory traversal vulnerability in the WinBox interface allowing unauthenticated attackers to read arbitrary files and authenticated attackers to write files. This vulnerability poses severe risks to network infrastructure security across organizations.

📄 Description (Arabic)

ثغرة اجتياز الدليل في واجهة WinBox بنظام MikroTik RouterOS تسمح للمهاجمين غير المصرحين بقراءة أي ملفات على النظام وللمهاجمين المصرحين بتعديل أو كتابة ملفات حساسة. هذا يمكن أن يؤدي إلى كشف بيانات حساسة وتعطيل الخدمات والسيطرة الكاملة على جهاز التوجيه.

🤖 ملخص تنفيذي (AI)

يحتوي نظام تشغيل MikroTik RouterOS حتى الإصدار 6.42 على ثغرة حرجة في واجهة WinBox تسمح للمهاجمين غير المصرحين بقراءة ملفات عشوائية والمهاجمين المصرحين بكتابة الملفات. تشكل هذه الثغرة مخاطر شديدة على أمان البنية التحتية للشبكة عبر المنظمات.
