📄 Description (English)

Build Smart ERP 21.0817 contains an unauthenticated SQL injection vulnerability in the 'eidValue' parameter of the login validation endpoint. Attackers can inject stacked SQL queries using payloads like ';WAITFOR DELAY '0:0:3'-- to manipulate database queries and potentially extract or modify database information.

🤖 AI Executive Summary

CVE-2021-47777 is a critical unauthenticated SQL injection vulnerability in Build Smart ERP 21.0817 affecting the login validation endpoint. Attackers can exploit the 'eidValue' parameter to inject malicious SQL queries, potentially leading to unauthorized database access, data exfiltration, or manipulation without requiring authentication. This vulnerability poses an immediate threat to organizations using this ERP system, particularly in Saudi Arabia's financial and government sectors.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: Apr 25, 2026 17:55
🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses severe risk to Saudi banking institutions (SAMA-regulated banks), government agencies (NCA oversight), and large enterprises using Build Smart ERP. The unauthenticated nature allows attackers to bypass security controls entirely. High-risk sectors include: Banking & Financial Services (direct database access to customer/transaction data), Government & Public Administration (sensitive citizen records), Healthcare (patient data exposure), and Energy sector (operational data). Organizations managing critical infrastructure or handling PII are at elevated risk of data breaches, regulatory violations under SAMA and NCA frameworks, and operational disruption.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all instances of Build Smart ERP 21.0817 in your environment and isolate affected systems from production networks if possible
2. Implement network-level access controls restricting access to the login validation endpoint to trusted IP ranges only
3. Enable Web Application Firewall (WAF) rules to block SQL injection patterns in the 'eidValue' parameter (block payloads containing: WAITFOR, UNION, SELECT, stacked queries with semicolons)
4. Monitor database logs for suspicious query patterns and unauthorized access attempts

PATCHING:
5. Apply the available patch immediately to Build Smart ERP 21.0817 - contact vendor for patch availability and deployment timeline
6. Test patch in non-production environment before production deployment
7. Verify patch effectiveness by attempting known SQL injection payloads in test environment

COMPENSATING CONTROLS (if patch unavailable temporarily):
8. Implement input validation/sanitization at application layer - whitelist allowed characters in 'eidValue' parameter
9. Use parameterized queries and prepared statements for all database interactions
10. Apply principle of least privilege to database service accounts
11. Enable database activity monitoring and alerting for anomalous queries

DETECTION:
12. Deploy IDS/IPS signatures detecting SQL injection attempts (Snort/Suricata rules for WAITFOR, stacked queries)
13. Monitor HTTP logs for suspicious 'eidValue' parameters containing SQL keywords
14. Alert on failed login attempts followed by database errors
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع نسخ Build Smart ERP 21.0817 في بيئتك وعزل الأنظمة المتأثرة عن شبكات الإنتاج إن أمكن
2. تطبيق عناصر التحكم في الوصول على مستوى الشبكة لتقييد الوصول إلى نقطة نهاية التحقق من تسجيل الدخول إلى نطاقات IP موثوقة فقط
3. تفعيل قواعد جدار حماية تطبيقات الويب (WAF) لحجب أنماط حقن SQL في معامل 'eidValue' (حجب الحمولات التي تحتوي على: WAITFOR، UNION، SELECT، الاستعلامات المكدسة بفواصل منقوطة)
4. مراقبة سجلات قاعدة البيانات للأنماط المريبة ومحاولات الوصول غير المصرح بها

التصحيح:
5. تطبيق التصحيح المتاح فوراً على Build Smart ERP 21.0817 - اتصل بالمورد للحصول على توفر التصحيح وجدول النشر
6. اختبر التصحيح في بيئة غير الإنتاج قبل نشر الإنتاج
7. تحقق من فعالية التصحيح بمحاولة حمولات حقن SQL المعروفة في بيئة الاختبار

عناصر التحكم التعويضية:
8. تطبيق التحقق من صحة المدخلات/التطهير على مستوى التطبيق - قائمة بيضاء للأحرف المسموحة في معامل 'eidValue'
9. استخدام الاستعلامات المعاملة والعبارات المحضرة لجميع تفاعلات قاعدة البيانات
10. تطبيق مبدأ أقل امتياز على حسابات خدمة قاعدة البيانات
11. تفعيل مراقبة نشاط قاعدة البيانات والتنبيهات للاستعلامات الشاذة

الكشف:
12. نشر توقيعات IDS/IPS للكشف عن محاولات حقن SQL (قواعد Snort/Suricata لـ WAITFOR والاستعلامات المكدسة)
13. مراقبة سجلات HTTP لمعاملات 'eidValue' المريبة التي تحتوي على كلمات رئيسية SQL
14. التنبيه على محاولات تسجيل الدخول الفاشلة متبوعة بأخطاء قاعدة البيانات
