🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Roundcube Webmail instances in your environment and document versions
2. Disable search functionality immediately if patching cannot be completed within 24 hours
3. Implement Web Application Firewall (WAF) rules to block SQL injection patterns in search parameters
4. Monitor database logs for suspicious SQL queries and unauthorized access attempts

PATCHING:
1. Upgrade to Roundcube 1.4.13 or later (1.5.x users upgrade to 1.5.2 or later)
2. Apply patches from official Roundcube repository only
3. Test patches in staging environment before production deployment
4. Verify search functionality after patching

COMPENSATING CONTROLS:
1. Restrict Roundcube access to internal networks only using VPN/IP whitelisting
2. Implement strong authentication (MFA) for all webmail accounts
3. Deploy database activity monitoring (DAM) to detect SQL injection attempts
4. Use parameterized queries validation at application level

DETECTION:
1. Monitor HTTP logs for search parameters containing SQL keywords (UNION, SELECT, DROP, etc.)
2. Alert on database connection errors from webmail application
3. Track unusual database query patterns and failed authentication attempts
4. Implement IDS/IPS signatures for Roundcube SQL injection CVE-2021-44026
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع نسخ Roundcube Webmail في بيئتك وتوثيق الإصدارات
2. تعطيل وظيفة البحث فوراً إذا لم يتمكن من إكمال التصحيح خلال 24 ساعة
3. تطبيق قواعد جدار حماية تطبيقات الويب (WAF) لحجب أنماط حقن SQL في معاملات البحث
4. مراقبة سجلات قاعدة البيانات للاستعلامات SQL المريبة ومحاولات الوصول غير المصرح بها

التصحيح:
1. الترقية إلى Roundcube 1.4.13 أو أحدث (مستخدمو 1.5.x يرقون إلى 1.5.2 أو أحدث)
2. تطبيق التصحيحات من مستودع Roundcube الرسمي فقط
3. اختبار التصحيحات في بيئة التجريب قبل نشر الإنتاج
4. التحقق من وظيفة البحث بعد التصحيح

الضوابط البديلة:
1. تقييد وصول Roundcube إلى الشبكات الداخلية فقط باستخدام VPN/قائمة بيضاء IP
2. تطبيق المصادقة القوية (MFA) لجميع حسابات البريد الإلكتروني
3. نشر مراقبة نشاط قاعدة البيانات (DAM) للكشف عن محاولات حقن SQL
4. استخدام التحقق من الاستعلامات المعاملة على مستوى التطبيق

الكشف:
1. مراقبة سجلات HTTP لمعاملات البحث التي تحتوي على كلمات رئيسية SQL (UNION, SELECT, DROP, إلخ)
2. التنبيه على أخطاء اتصال قاعدة البيانات من تطبيق البريد الإلكتروني
3. تتبع أنماط استعلامات قاعدة البيانات غير العادية ومحاولات المصادقة الفاشلة
4. تطبيق توقيعات IDS/IPS لـ CVE-2021-44026 Roundcube SQL Injection
