📄 Description (English)
Redis is an in-memory data structure store. In versions of redis-server up to 8.6.3, the RESTORE command does not properly validate serialized values. An authenticated attacker with permission to execute RESTORE can supply a crafted serialized payload that triggers invalid memory access and may lead to remote code execution. A workaround is to restrict access to the RESTORE command with ACL rules. This is patched in version 8.6.3.
🤖 AI Executive Summary
CVE-2026-25243 is a critical vulnerability in Redis versions up to 8.6.3 affecting the RESTORE command, allowing authenticated attackers to execute arbitrary code through malformed serialized payloads. With a CVSS score of 8.8, this poses significant risk to Saudi organizations relying on Redis for caching, session management, and real-time data processing. Immediate patching or access restriction via ACL rules is essential to prevent exploitation.

🇸🇦 Saudi Arabia Impact Assessment
Banking sector (SAMA-regulated institutions, payment processors) faces critical risk as Redis is widely used for transaction caching and session management. Government agencies and NCA-regulated entities using Redis for citizen services and data processing are at high risk. Healthcare sector (MOH systems, hospital management) could experience service disruption. Energy sector (ARAMCO, utilities) relying on Redis for SCADA data caching and real-time monitoring faces operational risk. Telecom operators (STC, Mobily, Zain) using Redis for subscriber data and billing systems are vulnerable. E-commerce and fintech platforms operating in Saudi Arabia are particularly exposed.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Redis instances in your infrastructure running versions ≤8.6.3 using: redis-cli INFO server | grep redis_version
2. Restrict RESTORE command access immediately via ACL rules: ACL SETUSER default -@all +@read +@write -restore
3. Implement network segmentation to limit Redis access to trusted application servers only
4. Enable Redis AUTH with strong passwords if not already configured
5. Monitor Redis logs for RESTORE command attempts: grep RESTORE /var/log/redis/redis-server.log
PATCHING GUIDANCE:
1. Upgrade to Redis 8.6.3 or later when available (currently no patch released - monitor redis.io/download)
2. For production systems, test patches in staging environment first
3. Plan maintenance window with minimal business impact
4. Backup Redis data before patching: redis-cli --rdb /backup/dump.rdb
COMPENSATING CONTROLS (until patch available):
1. Disable RESTORE command entirely if not required: ACL SETUSER default -restore
2. Implement Redis Sentinel or Cluster for high availability during remediation
3. Deploy WAF/IDS rules to detect malformed RESTORE payloads
4. Implement Redis command auditing and alerting
5. Restrict Redis port (6379) access via firewall to application servers only
DETECTION RULES:
1. Alert on any RESTORE command execution: redis-cli MONITOR | grep RESTORE
2. Monitor for connection attempts from unauthorized IPs
3. Track memory access violations in Redis logs
4. Set up alerts for Redis process crashes or unexpected restarts
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع مثيلات Redis في البنية التحتية الخاصة بك التي تعمل بالإصدارات ≤8.6.3 باستخدام: redis-cli INFO server | grep redis_version
2. قيد الوصول إلى أمر RESTORE فوراً عبر قواعد ACL: ACL SETUSER default -@all +@read +@write -restore
3. طبق تقسيم الشبكة لتحديد وصول Redis إلى خوادم التطبيقات الموثوقة فقط
4. فعّل مصادقة Redis بكلمات مرور قوية إن لم تكن مفعلة
5. راقب سجلات Redis لمحاولات أمر RESTORE: grep RESTORE /var/log/redis/redis-server.log
إرشادات التصحيح:
1. قم بالترقية إلى Redis 8.6.3 أو إصدار أحدث عند توفره (لا يوجد تصحيح حالياً - راقب redis.io/download)
2. بالنسبة لأنظمة الإنتاج، اختبر التصحيحات في بيئة التجريب أولاً
3. خطط لنافذة صيانة بأقل تأثير على الأعمال
4. احفظ بيانات Redis قبل التصحيح: redis-cli --rdb /backup/dump.rdb
الضوابط البديلة (حتى توفر التصحيح):
1. عطّل أمر RESTORE بالكامل إذا لم يكن مطلوباً: ACL SETUSER default -restore
2. طبق Redis Sentinel أو Cluster لتوفر عالي أثناء المعالجة
3. نشر قواعد WAF/IDS للكشف عن حمولات RESTORE المشوهة
4. طبق تدقيق أوامر Redis والتنبيهات
5. قيد وصول منفذ Redis (6379) عبر جدار الحماية إلى خوادم التطبيقات فقط
قواعد الكشف:
1. تنبيه عند تنفيذ أي أمر RESTORE: redis-cli MONITOR | grep RESTORE
2. راقب محاولات الاتصال من عناوين IP غير مصرح بها
3. تتبع انتهاكات الوصول إلى الذاكرة في سجلات Redis
4. قم بإعداد تنبيهات لأعطال عملية Redis أو إعادة تشغيل غير متوقعة
