📄 Description (English)

RELATE is a web-based courseware package. Prior to commit 2f68e16, there is a timing attack vulnerability in course/auth.py — check_sign_in_key(). This issue has been patched via commit 2f68e16.

🤖 AI Executive Summary

CVE-2026-41588 is a critical timing attack vulnerability in RELATE courseware's authentication mechanism (check_sign_in_key function) that allows attackers to bypass authentication through statistical analysis of response times. With a CVSS score of 9.0, this vulnerability poses severe risk to educational institutions and organizations using RELATE for course delivery and credential management. Immediate patching to commit 2f68e16 or later is essential to prevent unauthorized access to sensitive educational data and course materials.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: May 13, 2026 02:33
🇸🇦 Saudi Arabia Impact Assessment
Saudi educational institutions, particularly universities and technical colleges using RELATE for online course delivery and student authentication, face critical risk. Government education sector (Ministry of Education, ARAMCO training programs) and private educational providers are most vulnerable. The timing attack could enable unauthorized access to student records, course materials, and assessment data. Financial impact includes potential data breaches affecting thousands of students and staff. Compliance implications for SAMA-regulated institutions offering online training and NCA-governed educational technology platforms are significant.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all RELATE installations in your organization using asset inventory tools
2. Check current RELATE version against affected versions (all versions prior to commit 2f68e16)
3. Isolate affected RELATE instances from production if immediate patching is not possible
4. Review authentication logs for suspicious timing patterns or failed login attempts

PATCHING GUIDANCE:
1. Apply patch commit 2f68e16 or upgrade to the latest patched RELATE version immediately
2. Test authentication functionality thoroughly in staging environment before production deployment
3. Implement automated patching procedures for future RELATE updates

COMPENSATING CONTROLS (if patching delayed):
1. Implement rate limiting on authentication endpoints (max 5 attempts per minute per IP)
2. Add constant-time comparison functions to all authentication checks
3. Deploy Web Application Firewall (WAF) rules to detect timing attack patterns
4. Enable multi-factor authentication (MFA) for all user accounts
5. Implement account lockout after 3 failed login attempts

DETECTION RULES:
1. Monitor for repeated authentication requests with varying response times from same IP
2. Alert on authentication attempts with response time variance <50ms (indicates timing attack)
3. Track failed login attempts followed by successful logins within short timeframes
4. Log all authentication events with precise timestamps for forensic analysis
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع تثبيتات RELATE في المنظمة باستخدام أدوات جرد الأصول
2. التحقق من إصدار RELATE الحالي مقابل الإصدارات المتأثرة (جميع الإصدارات السابقة للالتزام 2f68e16)
3. عزل مثيلات RELATE المتأثرة عن الإنتاج إذا لم يكن التصحيح الفوري ممكناً
4. مراجعة سجلات المصادقة للبحث عن أنماط توقيت مريبة أو محاولات تسجيل دخول فاشلة

إرشادات التصحيح:
1. تطبيق التصحيح 2f68e16 أو الترقية إلى أحدث إصدار معدل من RELATE فوراً
2. اختبار وظائف المصادقة بدقة في بيئة التجريب قبل نشر الإنتاج
3. تنفيذ إجراءات التصحيح الآلي لتحديثات RELATE المستقبلية

الضوابط البديلة (إذا تأخر التصحيح):
1. تنفيذ تحديد معدل على نقاط نهاية المصادقة (5 محاولات كحد أقصى في الدقيقة لكل عنوان IP)
2. إضافة دوال المقارنة ذات الوقت الثابت لجميع فحوصات المصادقة
3. نشر قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن أنماط هجوم التوقيت
4. تفعيل المصادقة متعددة العوامل (MFA) لجميع حسابات المستخدمين
5. تنفيذ قفل الحساب بعد 3 محاولات تسجيل دخول فاشلة

قواعد الكشف:
1. مراقبة طلبات المصادقة المتكررة مع أوقات استجابة متفاوتة من نفس عنوان IP
2. التنبيه على محاولات المصادقة مع تباين وقت الاستجابة <50ms (يشير إلى هجوم التوقيت)
3. تتبع محاولات تسجيل الدخول الفاشلة متبوعة بعمليات تسجيل دخول ناجحة في إطار زمني قصير
4. تسجيل جميع أحداث المصادقة مع الطوابع الزمنية الدقيقة للتحليل الجنائي
