CVE-2023-21492

Critical 🇺🇸 CISA KEV ⚡ Exploit Available
Samsung Mobile Devices ASLR Bypass via Sensitive Information Logging
Published: May 19, 2023  ·  Source: CISA_KEV
CVSS v3
9.0
🔗 NVD Official
📄 Description (English)

Samsung Mobile Devices Insertion of Sensitive Information Into Log File Vulnerability — Samsung mobile devices running Android 11, 12, and 13 contain an insertion of sensitive information into log file vulnerability that allows a privileged, local attacker to conduct an address space layout randomization (ASLR) bypass.

🤖 AI Executive Summary

CVE-2023-21492 is a critical vulnerability affecting Samsung mobile devices running Android 11-13, allowing privileged local attackers to bypass ASLR through sensitive information leakage in log files. With a CVSS score of 9.0 and publicly available exploits, this poses significant risk to Saudi government, banking, and enterprise users relying on Samsung devices for sensitive operations. Immediate patching is essential to prevent privilege escalation and memory corruption attacks.

📄 Description (Arabic)

تؤثر هذه الثغرة على أجهزة سامسونج المحمولة التي تعمل بإصدارات Android 11 و12 و13. يقوم النظام بإدراج معلومات حساسة تتعلق بتخطيط الذاكرة في ملفات السجل التي يمكن الوصول إليها من قبل المهاجمين الممتازين محليًا. يسمح هذا بتجاوز آلية ASLR الأمنية الحرجة، مما يمكن المهاجمين من التنبؤ بعناوين الذاكرة وتنفيذ هجمات متقدمة مثل استغلال الثغرات البرمجية.

🤖 ملخص تنفيذي (AI)

CVE-2023-21492 عبارة عن ثغرة حرجة تؤثر على أجهزة Samsung التي تعمل بنظام Android 11-13، مما يسمح للمهاجمين المحليين الممتازين بتجاوز ASLR من خلال تسرب المعلومات الحساسة في ملفات السجل. مع درجة CVSS 9.0 والاستغلالات المتاحة للجمهور، يشكل هذا خطراً كبيراً على مستخدمي الحكومة والبنوك والمؤسسات السعودية الذين يعتمدون على أجهزة Samsung للعمليات الحساسة. يعتبر التصحيح الفوري ضرورياً لمنع هجمات تصعيد الامتيازات وتلف الذاكرة.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability critically impacts Saudi banking sector (SAMA-regulated institutions using Samsung devices for mobile banking operations), government agencies (NCA, Ministry of Interior), healthcare providers (MOH), and energy sector (ARAMCO). Enterprise users across telecommunications (STC, Mobily) and financial services are at high risk. The ASLR bypass enables privilege escalation and potential access to sensitive data stored on devices, including authentication credentials, financial information, and classified government communications. Mobile device compromise could lead to lateral movement into corporate networks.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Samsung devices running Android 11, 12, or 13 in your organization using MDM/EMM solutions
2. Restrict physical access to Samsung devices and enforce strong device lock mechanisms
3. Disable USB debugging and developer options on all affected devices
4. Monitor device logs for suspicious local process execution

PATCHING GUIDANCE:
1. Deploy Samsung security updates immediately through OTA or manual installation
2. Prioritize devices with privileged access (admin accounts, financial systems access)
3. Verify patch installation: Settings > About Phone > Security Patch Level should reflect latest Samsung security update
4. Test patches in non-production environment first

COMPENSATING CONTROLS (if immediate patching delayed):
1. Implement strict MDM policies: disable local shell access, restrict app installation
2. Enable Knox Real-time Protection and Knox Vault features
3. Enforce full device encryption and secure boot verification
4. Implement network segmentation to isolate mobile devices from critical systems
5. Deploy mobile threat defense (MTD) solutions with behavioral analysis

DETECTION RULES:
1. Monitor for unauthorized access to /proc/[pid]/maps and memory mapping files
2. Alert on suspicious log file access patterns in /data/anr/ and /data/tombstones/
3. Detect privilege escalation attempts following local process execution
4. Monitor for ASLR bypass indicators: repeated memory address queries, kernel module enumeration
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع أجهزة Samsung التي تعمل بنظام Android 11 أو 12 أو 13 في مؤسستك باستخدام حلول MDM/EMM
2. تقييد الوصول المادي إلى أجهزة Samsung وفرض آليات قفل الجهاز القوية
3. تعطيل تصحيح أخطاء USB والخيارات المتقدمة على جميع الأجهزة المتأثرة
4. مراقبة سجلات الجهاز للتنفيذ المريب للعمليات المحلية

إرشادات التصحيح:
1. نشر تحديثات أمان Samsung على الفور عبر OTA أو التثبيت اليدوي
2. إعطاء الأولوية للأجهزة ذات الوصول المميز (حسابات المسؤول، وصول الأنظمة المالية)
3. التحقق من تثبيت التصحيح: الإعدادات > حول الهاتف > مستوى التصحيح الأمني يجب أن يعكس أحدث تحديث أمان Samsung
4. اختبار التصحيحات في بيئة غير الإنتاج أولاً

الضوابط البديلة (إذا تأخر التصحيح الفوري):
1. تنفيذ سياسات MDM صارمة: تعطيل الوصول المحلي للقشرة، تقييد تثبيت التطبيقات
2. تفعيل Knox Real-time Protection و Knox Vault
3. فرض تشفير الجهاز الكامل والتحقق من الإقلاع الآمن
4. تنفيذ تقسيم الشبكة لعزل الأجهزة المحمولة عن الأنظمة الحرجة
5. نشر حلول الدفاع ضد التهديدات المحمولة (MTD) مع التحليل السلوكي

قواعد الكشف:
1. مراقبة الوصول غير المصرح به إلى /proc/[pid]/maps وملفات خريطة الذاكرة
2. التنبيه على أنماط الوصول المريبة لملفات السجل في /data/anr/ و /data/tombstones/
3. كشف محاولات تصعيد الامتيازات بعد تنفيذ العملية المحلية
4. مراقبة مؤشرات تجاوز ASLR: استعلامات عناوين الذاكرة المتكررة، تعداد وحدات النواة
