📄 Description (English)
IBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 is vulnerable to HTTP header injection, caused by improper validation of input by the HOST headers. This could allow an attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking.
🤖 AI Executive Summary
IBM InfoSphere Information Server versions 11.7.0.0 through 11.7.1.6 contain an HTTP header injection vulnerability (CVE-2025-14807) due to improper HOST header validation. This medium-severity flaw enables attackers to conduct cross-site scripting, cache poisoning, and session hijacking attacks. No patch is currently available, requiring immediate compensating controls for affected Saudi organizations.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily impacts Saudi organizations in data integration and analytics sectors, particularly those using InfoSphere for ETL operations. Most at-risk sectors include: Banking and Financial Services (SAMA-regulated institutions using InfoSphere for data warehousing), Government agencies (NCA oversight), Healthcare organizations (MOH and private hospitals managing patient data), Energy sector (ARAMCO and downstream companies), and Telecommunications (STC, Mobily). The lack of available patches creates elevated risk for organizations unable to immediately upgrade or implement compensating controls.

🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all InfoSphere Information Server instances running versions 11.7.0.0-11.7.1.6 in your environment
2. Isolate affected systems from untrusted networks where possible
3. Implement network-level controls to restrict access to InfoSphere services
4. Review access logs for suspicious HOST header patterns
Compensating Controls (until patch available):
1. Deploy Web Application Firewall (WAF) rules to validate and sanitize HOST headers
2. Implement strict input validation on all HTTP headers at network perimeter
3. Configure reverse proxy/load balancer to normalize and validate HOST headers before reaching InfoSphere
4. Enable HTTP Strict Transport Security (HSTS) headers
5. Implement Content Security Policy (CSP) headers to mitigate XSS impact
6. Disable HTTP caching for sensitive InfoSphere responses
7. Enforce session binding and regeneration mechanisms
Detection Rules:
1. Monitor for HOST header values containing special characters: <, >, ", ', \n, \r
2. Alert on HOST headers with unusual length (>255 characters)
3. Track multiple different HOST headers from same source IP
4. Monitor for reflected content in HTTP responses matching injected HOST values
5. Log all 4xx/5xx errors related to header validation
Upgrade Planning:
1. Contact IBM for patch availability timeline
2. Plan upgrade to version 11.7.2.0 or later when available
3. Test patches in non-production environment first
4. Schedule maintenance window for production upgrades
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع نسخ IBM InfoSphere Information Server التي تعمل بالإصدارات 11.7.0.0-11.7.1.6 في بيئتك
2. عزل الأنظمة المتأثرة عن الشبكات غير الموثوقة قدر الإمكان
3. تطبيق ضوابط على مستوى الشبكة لتقييد الوصول إلى خدمات InfoSphere
4. مراجعة سجلات الوصول للأنماط المريبة في رؤوس HOST
الضوابط التعويضية (حتى توفر التصحيح):
1. نشر قواعد جدار حماية تطبيقات الويب (WAF) للتحقق من رؤوس HOST وتنظيفها
2. تطبيق التحقق الصارم من صحة جميع رؤوس HTTP على محيط الشبكة
3. تكوين الخادم الوكيل العكسي/موازن التحميل لتطبيع والتحقق من رؤوس HOST قبل وصولها إلى InfoSphere
4. تفعيل رؤوس HTTP Strict Transport Security (HSTS)
5. تطبيق سياسة أمان المحتوى (CSP) للتخفيف من تأثير XSS
6. تعطيل تخزين HTTP المؤقت للاستجابات الحساسة من InfoSphere
7. فرض آليات ربط الجلسة وإعادة التوليد
قواعد الكشف:
1. مراقبة قيم HOST التي تحتوي على أحرف خاصة: <, >, ", ', \n, \r
2. تنبيه على رؤوس HOST بطول غير عادي (>255 حرف)
3. تتبع رؤوس HOST المختلفة المتعددة من نفس عنوان IP المصدر
4. مراقبة المحتوى المعكوس في استجابات HTTP التي تطابق قيم HOST المحقونة
5. تسجيل جميع أخطاء 4xx/5xx المتعلقة بالتحقق من الرؤوس
تخطيط الترقية:
1. الاتصال بـ IBM للحصول على جدول زمني لتوفر التصحيح
2. التخطيط للترقية إلى الإصدار 11.7.2.0 أو أحدث عند توفره
3. اختبار التصحيحات في بيئة غير الإنتاج أولاً
4. جدولة نافذة صيانة لترقيات الإنتاج
