📄 Description (English)

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, the nginx-ui application is vulnerable to a Race Condition. Due to the complete absence of synchronization mechanisms (Mutex) and non-atomic file writes, concurrent requests lead to the severe corruption of the primary configuration file (app.ini). This vulnerability results in a persistent Denial of Service (DoS) and introduces a non-deterministic path for Remote Code Execution (RCE) through configuration cross-contamination. This issue has been patched in version 2.3.4.

🤖 AI Executive Summary

Nginx UI versions prior to 2.3.4 contain a race condition vulnerability in file handling that allows concurrent requests to corrupt the app.ini configuration file, causing persistent denial of service. The vulnerability also creates potential pathways for remote code execution through configuration cross-contamination without proper synchronization mechanisms.

📄 Description (Arabic)

يؤثر هذا الضعف على Nginx UI بسبب غياب كامل لآليات المزامنة والكتابة الذرية للملفات. يمكن للمهاجمين استغلال الطلبات المتزامنة لإفساد ملف التكوين الرئيسي، مما يؤدي إلى رفض الخدمة المستمر وإمكانية تنفيذ أوامر بعيدة.

🤖 ملخص تنفيذي (AI)

تطبيق Nginx UI الإصدارات السابقة للإصدار 2.3.4 يحتوي على ثغرة تنافس في معالجة الملفات تسمح للطلبات المتزامنة بإفساد ملف التكوين app.ini، مما يسبب رفض خدمة مستمر. تخلق الثغرة أيضاً مسارات محتملة لتنفيذ أوامر بعيدة من خلال التلوث المتبادل للتكوين.

🔧 Remediation Steps (English)
Immediately upgrade Nginx UI to version 2.3.4 or later which includes proper mutex synchronization and atomic file write operations. Implement access controls to restrict who can modify Nginx UI configurations. Monitor for unusual concurrent requests and implement rate limiting on configuration endpoints. Validate all configuration changes before applying them to production systems.
🔧 خطوات المعالجة (العربية)
قم بترقية Nginx UI فوراً إلى الإصدار 2.3.4 أو أحدث الذي يتضمن آليات مزامنة mutex مناسبة وعمليات كتابة ملفات ذرية. طبق ضوابط الوصول لتقييد من يمكنه تعديل تكوينات Nginx UI. راقب الطلبات المتزامنة غير العادية وطبق تحديد معدل على نقاط نهاية التكوين. تحقق من صحة جميع تغييرات التكوين قبل تطبيقها على أنظمة الإنتاج.
