📄 Description (English)
Default configurations of Apache Shiro have a session fixation vulnerability.
This issue affects Apache Shiro from 1.0 to 2.1.0, and 3.0.0-alpha-1.
Users are recommended to upgrade to version 2.1.1, or 3.0.0-alpha-2 or later, which fixes the issue.
In the affected versions, when a session already exists, it is not invalidated upon successful login, nor is a new session being generated with a new ID.
🤖 AI Executive Summary
Apache Shiro versions 1.0-2.1.0 and 3.0.0-alpha-1 contain a session fixation vulnerability (CVE-2026-43827) where existing sessions are not invalidated upon successful login, allowing attackers to hijack user sessions. With a CVSS score of 6.5, this medium-severity vulnerability poses significant risk to Saudi organizations using Shiro for authentication, particularly in banking and government sectors. Immediate patching to version 2.1.1 or 3.0.0-alpha-2+ is critical to prevent unauthorized access and session hijacking attacks.

🇸🇦 Saudi Arabia Impact Assessment
Saudi banking institutions (SAMA-regulated) and government agencies (NCA oversight) are at highest risk as they heavily rely on Java-based authentication frameworks like Shiro. Financial services, e-commerce platforms, and healthcare systems using Shiro for session management face session hijacking risks. ARAMCO and critical infrastructure operators using Shiro-based applications could experience unauthorized access to sensitive systems. Telecom providers (STC, Mobily) managing customer authentication through Shiro are vulnerable to account takeover attacks. The vulnerability enables attackers to maintain persistent access to user accounts without re-authentication.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Inventory all Apache Shiro deployments across your organization, including version numbers and deployment contexts
2. Identify systems running Shiro versions 1.0-2.1.0 or 3.0.0-alpha-1
3. Assess business criticality of affected systems
PATCHING GUIDANCE:
1. Upgrade to Apache Shiro 2.1.1 or 3.0.0-alpha-2 or later immediately
2. Test patches in non-production environments first
3. Plan maintenance windows for production upgrades
4. Verify session invalidation behavior post-upgrade
COMPENSATING CONTROLS (if immediate patching not possible):
1. Implement strict session timeout policies (15-30 minutes for sensitive operations)
2. Force session re-authentication for sensitive transactions
3. Monitor for suspicious session activity patterns
4. Implement IP-based session binding to detect session hijacking
5. Enable comprehensive audit logging of all authentication events
DETECTION RULES:
1. Monitor for multiple concurrent sessions from same user account
2. Alert on session IDs remaining unchanged after login events
3. Track authentication logs for sessions without corresponding login records
4. Detect geographic anomalies in session usage patterns
5. Monitor for session activity from unexpected IP addresses or user agents
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع نشرات Apache Shiro عبر مؤسستك، بما في ذلك أرقام الإصدارات وسياقات النشر
2. حدد الأنظمة التي تعمل بإصدارات Shiro 1.0-2.1.0 أو 3.0.0-alpha-1
3. قيّم الأهمية التجارية للأنظمة المتأثرة
إرشادات التصحيح:
1. قم بالترقية إلى Apache Shiro 2.1.1 أو 3.0.0-alpha-2 أو إصدار أحدث فوراً
2. اختبر التصحيحات في بيئات غير الإنتاج أولاً
3. خطط لنوافذ الصيانة لترقيات الإنتاج
4. تحقق من سلوك إلغاء الجلسة بعد الترقية
الضوابط البديلة (إذا لم يكن التصحيح الفوري ممكناً):
1. تطبيق سياسات انتهاء الجلسة الصارمة (15-30 دقيقة للعمليات الحساسة)
2. فرض إعادة مصادقة الجلسة للمعاملات الحساسة
3. مراقبة أنماط نشاط الجلسة المريبة
4. تطبيق ربط الجلسة القائم على IP لكشف اختطاف الجلسة
5. تفعيل تسجيل التدقيق الشامل لجميع أحداث المصادقة
قواعد الكشف:
1. مراقبة جلسات متعددة متزامنة من نفس حساب المستخدم
2. تنبيهات على بقاء معرفات الجلسة دون تغيير بعد أحداث تسجيل الدخول
3. تتبع سجلات المصادقة للجلسات بدون سجلات تسجيل دخول مقابلة
4. كشف الشذوذ الجغرافي في أنماط استخدام الجلسة
5. مراقبة نشاط الجلسة من عناوين IP أو وكلاء مستخدمين غير متوقعين
