📄 Description (English)

ZEBRA is a Zcash node written entirely in Rust. From zebrad versions 2.2.0 to before 4.3.1 and from zebra-rpc versions 1.0.0-beta.45 to before 6.0.2, a vulnerability in Zebra's JSON-RPC HTTP middleware allows an authenticated RPC client to cause a Zebra node to crash by disconnecting before the request body is fully received. The node treats the failure to read the HTTP request body as an unrecoverable error and aborts the process instead of returning an error response. This issue has been patched in zebrad version 4.3.1 and zebra-rpc version 6.0.2.

🤖 AI Executive Summary

A vulnerability in Zebra's JSON-RPC HTTP middleware allows authenticated RPC clients to crash Zcash nodes by disconnecting before sending complete request bodies. The affected versions treat incomplete reads as fatal errors instead of recoverable failures, impacting node availability.

📄 Description (Arabic)

تؤثر هذه الثغرة على عقد Zcash التي تعمل بإصدارات Zebra من 2.2.0 إلى 4.3.0 و zebra-rpc من 1.0.0-beta.45 إلى 6.0.1. يمكن لعميل RPC مصرح له بقطع الاتصال قبل إرسال جسم الطلب بالكامل مما يؤدي إلى توقف العقدة بشكل غير متوقع.

🤖 ملخص تنفيذي (AI)

ثغرة في برنامج وسيط Zebra JSON-RPC تسمح للعملاء المصرح لهم بإيقاف عقد Zcash عن طريق قطع الاتصال قبل إرسال أجسام الطلب الكاملة. تعامل الإصدارات المتأثرة القراءات غير المكتملة كأخطاء قاتلة بدلاً من الأخطاء القابلة للاسترجاع.

🔧 Remediation Steps (English)
Update zebrad to version 4.3.1 or later and zebra-rpc to version 6.0.2 or later. Implement network-level access controls to restrict RPC endpoint access to trusted clients only. Monitor node logs for unexpected disconnections and implement connection timeout policies.
🔧 خطوات المعالجة (العربية)
قم بتحديث zebrad إلى الإصدار 4.3.1 أو أحدث و zebra-rpc إلى الإصدار 6.0.2 أو أحدث. قم بتنفيذ عناصر تحكم في الوصول على مستوى الشبكة لتقييد وصول نقطة نهاية RPC للعملاء الموثوقين فقط. راقب سجلات العقدة للقطع غير المتوقع وقم بتنفيذ سياسات انتظار الاتصال.
