📄 Description (English)

IBM Aspera Shares 1.9.9 through 1.11.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information

🤖 AI Executive Summary

IBM Aspera Shares versions 1.9.9 through 1.11.0 contain weak cryptographic algorithms (CWE-327) that could enable attackers to decrypt sensitive data. With a CVSS score of 5.9, this vulnerability poses a medium risk to organizations using affected versions for secure file transfer and collaboration. No patch is currently available, requiring immediate compensating controls and version assessment.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: May 24, 2026 11:18
🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations in banking (SAMA-regulated institutions), government agencies (NCA oversight), healthcare (MOH), energy sector (ARAMCO, SEC), and telecommunications (STC, Mobily) using Aspera Shares for secure data exchange face decryption risks. Financial institutions and government entities handling classified or sensitive data are particularly vulnerable. The lack of available patches increases exposure duration for critical infrastructure operators.

🔧 Remediation Steps (English)
1. IMMEDIATE ACTIONS:
- Inventory all IBM Aspera Shares deployments and identify affected versions (1.9.9-1.11.0)
- Assess data sensitivity and exposure risk for each instance
- Isolate or restrict network access to affected Aspera Shares instances
- Review access logs for unauthorized decryption attempts

2. PATCHING GUIDANCE:
- Monitor IBM security advisories for patch availability
- Plan upgrade to version 1.11.1 or later when released
- Test patches in non-production environments before deployment

3. COMPENSATING CONTROLS:
- Implement network segmentation and firewall rules limiting Aspera access
- Enable additional encryption layers (TLS 1.3+) for data in transit
- Deploy VPN/zero-trust access controls for Aspera Shares users
- Implement data loss prevention (DLP) tools to monitor sensitive file transfers
- Enforce multi-factor authentication for all Aspera Shares access
- Conduct cryptographic audit of stored data encryption methods

4. DETECTION RULES:
- Monitor for unusual decryption operations or failed authentication attempts
- Alert on access to Aspera Shares from unexpected IP ranges
- Track file access patterns for sensitive data repositories
- Log all administrative changes to Aspera Shares configuration
🔧 خطوات المعالجة (العربية)
1. الإجراءات الفورية:
- حصر جميع نشرات IBM Aspera Shares وتحديد الإصدارات المتأثرة (1.9.9-1.11.0)
- تقييم حساسية البيانات ومخاطر التعرض لكل مثيل
- عزل أو تقييد الوصول الشبكي لمثيلات Aspera Shares المتأثرة
- مراجعة سجلات الوصول لمحاولات فك التشفير غير المصرح بها

2. إرشادات التصحيح:
- مراقبة استشارات أمان IBM لتوفر التصحيحات
- التخطيط للترقية إلى الإصدار 1.11.1 أو أحدث عند إصداره
- اختبار التصحيحات في بيئات غير الإنتاج قبل النشر

3. الضوابط التعويضية:
- تطبيق تقسيم الشبكة وقواعد جدار الحماية لتحديد وصول Aspera
- تفعيل طبقات تشفير إضافية (TLS 1.3+) للبيانات أثناء النقل
- نشر VPN/ضوابط الوصول بدون ثقة لمستخدمي Aspera Shares
- تطبيق أدوات منع فقدان البيانات (DLP) لمراقبة نقل الملفات الحساسة
- فرض المصادقة متعددة العوامل لجميع وصول Aspera Shares
- إجراء تدقيق تشفيري لطرق تشفير البيانات المخزنة

4. قواعد الكشف:
- مراقبة عمليات فك التشفير غير العادية أو محاولات المصادقة الفاشلة
- تنبيهات الوصول إلى Aspera Shares من نطاقات IP غير متوقعة
- تتبع أنماط الوصول إلى الملفات لمستودعات البيانات الحساسة
- تسجيل جميع التغييرات الإدارية لإعدادات Aspera Shares
