📄 Description (English)

Insufficient session expiration vulnerability in Turkiye Electricity Transmission Corporation (TEİAŞ) Mobile Application allows Session Hijacking.

This issue affects Mobile Application: from 1.6.2 before 1.13.

🤖 AI Executive Summary

CVE-2026-1815 is a session management vulnerability in TEİAŞ mobile application (versions 1.6.2-1.13) that allows attackers to hijack user sessions through insufficient session expiration controls. While the CVSS score is medium (5.7), the lack of available patches and exploit availability creates operational risk for energy sector users. This vulnerability is particularly concerning for critical infrastructure operators who rely on mobile applications for grid management and monitoring.

🇸🇦 Saudi Arabia Impact Assessment
While this CVE affects Turkish infrastructure, Saudi organizations in the energy sector (particularly Saudi Aramco and SEC) that may use similar mobile application architectures or have cross-border energy management systems are at moderate risk. The vulnerability could impact: (1) Energy/Utilities sector - if similar session management patterns exist in Saudi energy infrastructure applications; (2) Government agencies managing critical infrastructure - NCA and relevant ministries monitoring energy systems; (3) Telecom operators (STC, Mobily) - if they provide energy sector connectivity solutions. The session hijacking risk could lead to unauthorized access to critical infrastructure monitoring and control systems.

🔧 Remediation Steps (English)
Immediate Actions:
1. Audit all mobile applications in your organization for similar session expiration vulnerabilities, particularly those managing critical infrastructure or sensitive operations
2. Implement mandatory session timeout policies (15-30 minutes for sensitive operations, 60 minutes for standard operations)
3. Disable session reuse across different devices/IP addresses
4. Implement certificate pinning in mobile applications to prevent man-in-the-middle attacks during session hijacking attempts

Compensating Controls (until patch available):
5. Deploy mobile device management (MDM) solutions to enforce application updates and security policies
6. Implement continuous session validation with server-side checks for anomalous behavior
7. Require multi-factor authentication (MFA) for all critical operations within mobile applications
8. Monitor for suspicious session activity: multiple concurrent sessions, geographic impossibilities, unusual access patterns
9. Implement rate limiting on authentication endpoints
10. Use secure, HttpOnly, and SameSite cookies with short expiration times

Detection Rules:
- Alert on multiple concurrent sessions from same user account
- Flag sessions with IP address changes without re-authentication
- Monitor for session tokens used across different device identifiers
- Track failed authentication attempts followed by successful sessions from different locations
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بتدقيق جميع تطبيقات الهاتف المحمول في مؤسستك بحثاً عن ثغرات مماثلة في انتهاء الجلسة، خاصة تلك التي تدير البنية التحتية الحرجة أو العمليات الحساسة
2. تنفيذ سياسات انتهاء الجلسة الإلزامية (15-30 دقيقة للعمليات الحساسة، 60 دقيقة للعمليات القياسية)
3. تعطيل إعادة استخدام الجلسة عبر الأجهزة/عناوين IP المختلفة
4. تنفيذ تثبيت الشهادات في تطبيقات الهاتف المحمول لمنع هجمات الوسيط

الضوابط التعويضية (حتى توفر التصحيح):
5. نشر حلول إدارة أجهزة الهاتف المحمول (MDM) لفرض تحديثات التطبيقات والسياسات الأمنية
6. تنفيذ التحقق المستمر من الجلسة مع فحوصات من جانب الخادم للسلوك الشاذ
7. طلب المصادقة متعددة العوامل (MFA) لجميع العمليات الحرجة داخل تطبيقات الهاتف المحمول
8. مراقبة نشاط الجلسة المريب: جلسات متزامنة متعددة، استحالات جغرافية، أنماط وصول غير عادية
9. تنفيذ تحديد معدل على نقاط نهاية المصادقة
10. استخدام ملفات تعريف آمنة وHttpOnly و SameSite مع أوقات انتهاء قصيرة

قواعد الكشف:
- تنبيه على جلسات متزامنة متعددة من حساب المستخدم نفسه
- وضع علامة على الجلسات مع تغييرات عنوان IP بدون إعادة مصادقة
- مراقبة رموز الجلسة المستخدمة عبر معرفات الأجهزة المختلفة
- تتبع محاولات المصادقة الفاشلة متبوعة بجلسات ناجحة من مواقع مختلفة
