📄 Description (English)

Improper Validation of Array Index (CWE-129) in the PostgreSQL protocol parser in Packetbeat can lead Denial of Service via Input Data Manipulation (CAPEC-153). An attacker can send a specially crafted packet causing a Go runtime panic that terminates the Packetbeat process. This vulnerability requires the pgsql protocol to be explicitly enabled and configured to monitor traffic on the targeted port.

🤖 AI Executive Summary

CVE-2026-26932 is a denial of service vulnerability in Packetbeat's PostgreSQL protocol parser caused by improper array index validation. An attacker can crash the Packetbeat process by sending specially crafted packets when PostgreSQL monitoring is enabled.

📄 Description (Arabic)

ثغرة في محلل بروتوكول PostgreSQL في Packetbeat تنتج عن فشل التحقق من صحة فهرس المصفوفة (CWE-129). يمكن لمهاجم استغلال هذه الثغرة بإرسال حزم مصممة خصيصاً لإحداث حالة panic في وقت تشغيل Go مما يؤدي إلى توقف عملية Packetbeat. الثغرة تتطلب تفعيل وتكوين بروتوكول PostgreSQL بشكل صريح لمراقبة حركة المرور على المنفذ المستهدف.

🤖 ملخص تنفيذي (AI)

🔧 Remediation Steps (English)
Update Packetbeat to the latest patched version that fixes CWE-129 array index validation. Disable PostgreSQL protocol monitoring if not required. Implement network segmentation to restrict access to Packetbeat monitoring ports. Monitor for unexpected process terminations and implement rate limiting on PostgreSQL traffic.
🔧 خطوات المعالجة (العربية)
قم بتحديث Packetbeat إلى أحدث إصدار مصحح يصلح التحقق من فهرس المصفوفة. عطّل مراقبة بروتوكول PostgreSQL إذا لم تكن مطلوبة. طبّق تقسيم الشبكة لتقييد الوصول إلى منافذ مراقبة Packetbeat. راقب إنهاء العمليات غير المتوقعة وطبّق تحديد معدل على حركة PostgreSQL.
