📄 Description (English)
Easy Chat Server 3.1 contains a denial of service vulnerability that allows remote attackers to crash the application by sending oversized data in the message parameter. Attackers can establish a session via the chat.ghp endpoint and then send a POST request to body2.ghp with an excessively large message parameter value to cause the service to crash.
🤖 AI Executive Summary
CVE-2019-25613 is a denial of service vulnerability in Easy Chat Server 3.1 that allows remote attackers to crash the application by sending oversized data through the message parameter. The vulnerability is exploitable without authentication after establishing a session, with a CVSS score of 7.5 indicating high severity. No patch is currently available, making immediate compensating controls essential for affected organizations.

🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all instances of Easy Chat Server 3.1 in your environment and document their criticality
2. Implement network-level input validation to reject POST requests to body2.ghp with message parameters exceeding 10KB
3. Deploy rate limiting on the chat.ghp endpoint to restrict session establishment attempts
4. Enable request size limits at the web server level (nginx/Apache) to block oversized payloads
Compensating Controls:
5. Implement Web Application Firewall (WAF) rules to detect and block requests with excessively large message parameters
6. Monitor for repeated connection attempts and POST requests from single IP addresses
7. Establish connection timeouts and resource limits per session
8. Deploy IDS/IPS signatures to detect DoS attack patterns
Detection Rules:
- Alert on POST requests to body2.ghp with Content-Length > 10KB
- Monitor for multiple failed requests from same source IP within 5-minute window
- Track application crash logs and correlate with incoming request patterns
- Implement baseline monitoring of CPU and memory usage per chat session
Long-term:
9. Evaluate migration to patched versions or alternative chat solutions
10. Conduct security assessment of Easy Chat Server deployment architecture
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع نسخ Easy Chat Server 3.1 في بيئتك وتوثيق أهميتها
2. تطبيق التحقق من صحة المدخلات على مستوى الشبكة لرفض طلبات POST إلى body2.ghp برسائل تتجاوز 10KB
3. نشر تحديد معدل على نقطة نهاية chat.ghp لتقييد محاولات إنشاء الجلسة
4. تفعيل حدود حجم الطلب على مستوى خادم الويب (nginx/Apache) لحجب الحمولات الكبيرة
الضوابط التعويضية:
5. تطبيق قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن طلبات بمعاملات رسائل كبيرة الحجم وحجبها
6. مراقبة محاولات الاتصال المتكررة وطلبات POST من عناوين IP واحدة
7. إنشاء انقطاعات الاتصال وحدود الموارد لكل جلسة
8. نشر توقيعات IDS/IPS للكشف عن أنماط هجمات DoS
قواعد الكشف:
- تنبيه على طلبات POST إلى body2.ghp مع Content-Length > 10KB
- مراقبة طلبات متعددة فاشلة من عنوان IP واحد خلال نافذة 5 دقائق
- تتبع سجلات توقف التطبيق والربط مع أنماط الطلبات الواردة
- تطبيق مراقبة خط الأساس لاستخدام CPU والذاكرة لكل جلسة دردشة
المدى الطويل:
9. تقييم الهجرة إلى إصدارات مصححة أو حلول دردشة بديلة
10. إجراء تقييم أمني لبنية نشر Easy Chat Server
