📄 Description (English)
An out-of-band SQL injection vulnerability (OOB SQLi) has been detected in the Performance Evaluation (EDD) application developed by Gabinete Técnico de Programación. Exploiting this vulnerability in the parameter 'Id_usuario' and 'Id_evaluacion' en ‘/evaluacion_inicio.aspx’, could allow an attacker to extract sensitive information from the database through external channels, without the affected application returning the data directly, compromising the confidentiality of the stored information.
🤖 AI Executive Summary
A high-severity out-of-band SQL injection vulnerability (CVE-2026-1474, CVSS 7.5) exists in the Performance Evaluation (EDD) application affecting the 'Id_usuario' and 'Id_evaluacion' parameters in '/evaluacion_inicio.aspx'. This OOB SQLi vulnerability allows attackers to extract sensitive database information through external channels without direct application feedback, posing significant confidentiality risks. A patch is available and should be deployed immediately to prevent unauthorized data exfiltration.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi government entities, particularly those using the EDD application for personnel performance evaluation systems. High-risk sectors include: (1) Government agencies under NCA oversight managing employee records and sensitive HR data; (2) ARAMCO and energy sector organizations using performance management systems; (3) Banking institutions (SAMA-regulated) if using this application for staff evaluation; (4) Healthcare organizations managing employee performance data. The OOB SQLi technique allows attackers to bypass WAF/IDS detection by exfiltrating data through DNS queries or HTTP requests to attacker-controlled servers, making detection challenging for Saudi SOCs without proper monitoring of external DNS/HTTP traffic patterns.

Government (NCA-regulated entities)
Energy (ARAMCO and petroleum sector)
Banking (SAMA-regulated institutions)
Healthcare (Ministry of Health)

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all instances of the Quatuor Performance Evaluation (EDD) application across your organization
2. Restrict network access to '/evaluacion_inicio.aspx' to authorized users only via firewall/WAF rules
3. Monitor outbound DNS and HTTP traffic for suspicious external communications
4. Review database access logs for unusual query patterns in the past 30 days
PATCHING:
5. Apply the available patch immediately to all affected EDD application instances
6. Test patch in staging environment before production deployment
7. Verify patch effectiveness by attempting exploitation in controlled environment
COMPENSATING CONTROLS (if patch deployment delayed):
8. Implement input validation and parameterized queries for 'Id_usuario' and 'Id_evaluacion' parameters
9. Deploy WAF rules to block SQL injection patterns in these parameters
10. Enable SQL query logging and alerting for suspicious database activity
11. Implement network segmentation to restrict database server access
12. Disable outbound DNS and HTTP from application servers to untrusted destinations
DETECTION:
13. Monitor for HTTP requests containing SQL keywords (UNION, SELECT, CAST, CONVERT) in parameter values
14. Alert on unusual outbound DNS queries from application servers
15. Track database connections with unusual query patterns or high data volume transfers
16. Implement SIEM rules: (a) Multiple failed authentication attempts to database, (b) Queries accessing system tables, (c) Data exfiltration patterns
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع نسخ تطبيق تقييم الأداء من Quatuor (EDD) في المنظمة
2. تقييد الوصول الشبكي إلى '/evaluacion_inicio.aspx' للمستخدمين المصرح لهم فقط عبر قواعد جدار الحماية/WAF
3. مراقبة حركة DNS و HTTP الصادرة للاتصالات الخارجية المريبة
4. مراجعة سجلات الوصول إلى قاعدة البيانات للأنماط غير العادية في آخر 30 يوماً
التصحيح:
5. تطبيق التصحيح المتاح فوراً على جميع نسخ تطبيق EDD المتأثرة
6. اختبار التصحيح في بيئة التجريب قبل نشره في الإنتاج
7. التحقق من فعالية التصحيح بمحاولة الاستغلال في بيئة محكومة
الضوابط البديلة (إذا تأخر نشر التصحيح):
8. تطبيق التحقق من صحة المدخلات والاستعلامات المعاملة لمعاملات 'Id_usuario' و'Id_evaluacion'
9. نشر قواعد WAF لحجب أنماط حقن SQL في هذه المعاملات
10. تفعيل تسجيل الاستعلامات وتنبيهات قاعدة البيانات للنشاط المريب
11. تطبيق تقسيم الشبكة لتقييد الوصول إلى خادم قاعدة البيانات
12. تعطيل DNS و HTTP الصادرة من خوادم التطبيق إلى الوجهات غير الموثوقة
الكشف:
13. مراقبة طلبات HTTP التي تحتوي على كلمات مفتاحية SQL (UNION, SELECT, CAST, CONVERT) في قيم المعاملات
14. التنبيه على استعلامات DNS الصادرة غير العادية من خوادم التطبيق
15. تتبع اتصالات قاعدة البيانات بأنماط استعلام غير عادية أو نقل بيانات بحجم كبير
16. تطبيق قواعد SIEM: (أ) محاولات مصادقة فاشلة متعددة لقاعدة البيانات، (ب) الاستعلامات التي تصل إلى جداول النظام، (ج) أنماط تسرب البيانات
