📄 Description (English)

A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus (Desktop Bus) setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication, leading to unauthorized changes in network security configurations.

🤖 AI Executive Summary

A firewalld vulnerability allows local unprivileged users to bypass D-Bus authentication on setZoneSettings2 and setPolicySettings methods, enabling unauthorized firewall configuration changes. This flaw could allow attackers to modify network security policies without proper authorization.

📄 Description (Arabic)

ثغرة في firewalld تتعلق بمصادقة D-Bus غير صحيحة حيث يمكن للمستخدمين المحليين غير المميزين استغلال طرق setZoneSettings2 و setPolicySettings لتعديل حالة جدار الحماية في وقت التشغيل. يؤدي هذا الخلل إلى تجاوز آليات التحكم في الوصول وتعريض سياسات الأمان الشبكي للخطر.

🤖 ملخص تنفيذي (AI)

ثغرة في firewalld تسمح للمستخدمين المحليين غير المميزين بتجاوز مصادقة D-Bus على طرق setZoneSettings2 و setPolicySettings، مما يتيح تغييرات غير مصرح بها في إعدادات جدار الحماية. يمكن لهذا الخلل أن يسمح للمهاجمين بتعديل سياسات الأمان الشبكي دون تفويض مناسب.
