📄 Description (English)
The Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin plugin for WordPress is vulnerable to blind SQL Injection via the `order` and `append_where_sql` parameters in all versions up to, and including, 1.6.9.9 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all WordPress installations using Simply Schedule Appointments Booking Plugin
2. Check plugin version against affected versions (up to 1.6.9.9)
3. Disable the plugin immediately if running vulnerable version
4. Review database access logs for suspicious SQL queries
PATCHING:
1. Update plugin to version 1.7.0 or later immediately
2. Ensure WordPress core and all other plugins are updated
3. Test updates in staging environment before production deployment
COMPENSATING CONTROLS (if immediate patching not possible):
1. Implement Web Application Firewall (WAF) rules to block SQL injection patterns in `order` and `append_where_sql` parameters
2. Restrict database user permissions to minimum required privileges
3. Enable database query logging and monitoring
4. Implement rate limiting on appointment booking endpoints
5. Disable plugin if not actively used
DETECTION:
1. Monitor for SQL keywords (UNION, SELECT, DROP, INSERT) in HTTP parameters
2. Alert on unusual database query patterns or failed authentication attempts
3. Review WordPress error logs for SQL syntax errors
4. Implement IDS/IPS signatures for blind SQL injection attempts
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع تثبيتات WordPress التي تستخدم مكون Simply Schedule Appointments Booking Plugin
2. التحقق من إصدار المكون مقابل الإصدارات المتأثرة (حتى 1.6.9.9)
3. تعطيل المكون فوراً إذا كان يعمل بإصدار معرض للخطر
4. مراجعة سجلات الوصول إلى قاعدة البيانات للاستعلامات المريبة
التصحيح:
1. تحديث المكون إلى الإصدار 1.7.0 أو أحدث فوراً
2. التأكد من تحديث نواة WordPress وجميع المكونات الأخرى
3. اختبار التحديثات في بيئة التطوير قبل النشر في الإنتاج
الضوابط البديلة (إذا لم يكن التصحيح الفوري ممكناً):
1. تنفيذ قواعد جدار حماية تطبيقات الويب (WAF) لحجب أنماط حقن SQL في معاملات `order` و `append_where_sql`
2. تقييد صلاحيات مستخدم قاعدة البيانات للحد الأدنى المطلوب
3. تفعيل تسجيل ومراقبة استعلامات قاعدة البيانات
4. تنفيذ تحديد معدل على نقاط نهاية حجز المواعيد
5. تعطيل المكون إذا لم يكن قيد الاستخدام النشط
الكشف:
1. مراقبة كلمات SQL الرئيسية (UNION, SELECT, DROP, INSERT) في معاملات HTTP
2. التنبيه على أنماط استعلامات قاعدة البيانات غير العادية أو محاولات المصادقة الفاشلة
3. مراجعة سجلات أخطاء WordPress لأخطاء بناء جملة SQL
4. تنفيذ توقيعات نظام كشف/منع الاختراق (IDS/IPS) لمحاولات حقن SQL العمياء
