📄 الوصف (الإنجليزية)
Internet Download Manager 6.38.12 contains a buffer overflow vulnerability in the Scheduler component that allows local attackers to crash the application by supplying oversized input. Attackers can paste malicious data exceeding 5000 bytes into the 'Open the following file when done' field to trigger a denial of service condition.
🤖 ملخص AI
CVE-2020-37234 is a local buffer overflow vulnerability in Internet Download Manager (IDM) 6.38.12 affecting the Scheduler component. An attacker with local access can crash the application by inputting oversized data (>5000 bytes) into a specific field, causing denial of service. While currently unpatched and without public exploits, this vulnerability poses moderate risk to organizations relying on IDM for download management, particularly in environments with untrusted local users.

🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all systems running Internet Download Manager 6.38.12 or earlier versions across your organization
2. Restrict local access to systems running IDM to trusted users only; implement access controls and user privilege management
3. Monitor for suspicious activity targeting IDM processes
Compensating Controls (No Patch Available):
1. Upgrade to the latest available version of Internet Download Manager (versions after 6.38.12 if available)
2. Implement application whitelisting to restrict IDM execution to authorized users
3. Use endpoint protection with behavioral analysis to detect buffer overflow attempts
4. Disable IDM Scheduler component if not required for operations
5. Run IDM with minimal privileges (non-administrator accounts)
6. Implement file integrity monitoring on IDM installation directories
Detection Rules:
1. Monitor for IDM process crashes or unexpected terminations
2. Alert on attempts to write data exceeding 5000 bytes to IDM configuration files
3. Track failed IDM Scheduler operations and error logs
4. Implement YARA rules to detect oversized input patterns in IDM-related processes
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع الأنظمة التي تقوم بتشغيل Internet Download Manager الإصدار 6.38.12 أو الإصدارات الأقدم عبر المنظمة
2. تقييد الوصول المحلي إلى الأنظمة التي تقوم بتشغيل IDM للمستخدمين الموثوقين فقط؛ تنفيذ عناصر التحكم في الوصول وإدارة امتيازات المستخدم
3. مراقبة النشاط المريب الموجه نحو عمليات IDM
عناصر التحكم التعويضية (لا يوجد تصحيح متاح):
1. الترقية إلى أحدث إصدار متاح من Internet Download Manager (الإصدارات بعد 6.38.12 إن أمكن)
2. تنفيذ قائمة بيضاء للتطبيقات لتقييد تنفيذ IDM للمستخدمين المصرح لهم
3. استخدام الحماية من نقاط النهاية مع التحليل السلوكي للكشف عن محاولات تجاوز المخزن المؤقت
4. تعطيل مكون IDM Scheduler إذا لم يكن مطلوباً للعمليات
5. تشغيل IDM بامتيازات دنيا (حسابات غير إدارية)
6. تنفيذ مراقبة سلامة الملفات على أدلة تثبيت IDM
قواعد الكشف:
1. مراقبة أعطال عمليات IDM أو الإنهاء غير المتوقع
2. التنبيه على محاولات كتابة البيانات التي تتجاوز 5000 بايت إلى ملفات تكوين IDM
3. تتبع عمليات IDM Scheduler الفاشلة وسجلات الأخطاء
4. تنفيذ قواعد YARA للكشف عن أنماط الإدخال الكبيرة الحجم في عمليات IDM
