📄 Description (English)

The User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder plugin for WordPress is vulnerable to SQL Injection via the ‘membership_ids[]’ parameter in all versions up to, and including, 5.1.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

🤖 AI Executive Summary

A SQL Injection vulnerability exists in the User Registration & Membership WordPress plugin (versions up to 5.1.2) affecting the 'membership_ids[]' parameter. Authenticated attackers with Subscriber-level access can inject malicious SQL queries to extract sensitive database information. While currently unpatched, the vulnerability requires authentication and has a CVSS score of 6.5, making it a moderate-risk threat to WordPress installations in Saudi Arabia.

/ 10.0
🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Audit all WordPress installations using User Registration & Membership plugin versions up to 5.1.2
2. Review database access logs for suspicious SQL patterns or unauthorized data extraction attempts
3. Check user activity logs for Subscriber-level accounts performing unusual queries
4. Identify and document all sensitive data accessible through affected plugin parameters

PATCHING GUIDANCE:
1. Monitor the plugin's official repository for security updates (currently no patch available)
2. Contact the plugin developer for patch timeline and interim security measures
3. Consider upgrading to alternative membership plugins with better security records

COMPENSATING CONTROLS (until patch available):
1. Restrict Subscriber-level account creation and audit existing accounts
2. Implement Web Application Firewall (WAF) rules to block SQL injection patterns in 'membership_ids[]' parameter
3. Apply database-level access controls limiting plugin user permissions to SELECT operations only
4. Disable the plugin if not actively used; use alternative solutions
5. Implement database activity monitoring and alerting for suspicious queries

DETECTION RULES:
1. Monitor for HTTP requests containing SQL keywords (UNION, SELECT, DROP, INSERT) in 'membership_ids[]' parameter
2. Alert on database queries from WordPress plugin user accounts containing unexpected SQL syntax
3. Track failed database authentication attempts from WordPress application user
4. Monitor for unusual data extraction patterns from user tables
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع تثبيتات WordPress التي تستخدم مكون User Registration & Membership بالإصدارات حتى 5.1.2
2. مراجعة سجلات الوصول إلى قاعدة البيانات للبحث عن أنماط SQL مريبة أو محاولات استخراج بيانات غير مصرح بها
3. فحص سجلات نشاط المستخدم لحسابات مستوى المشترك التي تقوم باستعلامات غير عادية
4. تحديد وتوثيق جميع البيانات الحساسة التي يمكن الوصول إليها من خلال معاملات المكون المتأثرة

إرشادات التصحيح:
1. مراقبة مستودع المكون الرسمي للتحديثات الأمنية (لا يوجد تصحيح متاح حالياً)
2. التواصل مع مطور المكون بشأن الجدول الزمني للتصحيح والتدابير الأمنية المؤقتة
3. النظر في الترقية إلى مكونات عضوية بديلة بسجلات أمان أفضل

الضوابط البديلة (حتى توفر التصحيح):
1. تقييد إنشاء حسابات مستوى المشترك وتدقيق الحسابات الموجودة
2. تنفيذ قواعد جدار حماية تطبيقات الويب (WAF) لحجب أنماط حقن SQL في معامل 'membership_ids[]'
3. تطبيق ضوابط الوصول على مستوى قاعدة البيانات التي تحد من أذونات مستخدم المكون لعمليات SELECT فقط
4. تعطيل المكون إذا لم يكن قيد الاستخدام النشط؛ استخدام حلول بديلة
5. تنفيذ مراقبة نشاط قاعدة البيانات والتنبيهات للاستعلامات المريبة

قواعد الكشف:
1. مراقبة طلبات HTTP التي تحتوي على كلمات مفتاحية SQL (UNION, SELECT, DROP, INSERT) في معامل 'membership_ids[]'
2. التنبيه على استعلامات قاعدة البيانات من حسابات مستخدمي مكون WordPress التي تحتوي على بناء جملة SQL غير متوقع
3. تتبع محاولات المصادقة الفاشلة في قاعدة البيانات من مستخدم تطبيق WordPress
4. مراقبة أنماط استخراج البيانات غير العادية من جداول المستخدمين
