📄 Description (English)
A weakness has been identified in JeecgBoot 3.9.0. Affected by this vulnerability is an unknown functionality of the file /sys/common/uploadImgByHttp. Executing a manipulation of the argument fileUrl can lead to server-side request forgery. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
🤖 AI Executive Summary
JeecgBoot 3.9.0 contains a Server-Side Request Forgery (SSRF) vulnerability in the /sys/common/uploadImgByHttp endpoint that allows remote attackers to manipulate the fileUrl parameter. This vulnerability enables attackers to make arbitrary HTTP requests from the affected server, potentially accessing internal resources, cloud metadata services, or launching attacks against internal infrastructure. With a CVSS score of 6.3 and no vendor patch available, immediate mitigation is critical for Saudi organizations using this framework.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi financial institutions, government agencies, and healthcare providers using JeecgBoot for internal applications. Banking sector (SAMA-regulated entities) faces risk of unauthorized access to internal banking systems and customer data. Government agencies using this framework for citizen services could experience data exfiltration or lateral movement attacks. Telecom operators (STC, Mobily) and energy sector organizations using JeecgBoot for administrative portals are at risk of internal network reconnaissance and compromise of critical infrastructure management systems. The SSRF vulnerability could be leveraged to access cloud-hosted resources (AWS, Azure) commonly used by Saudi enterprises.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all instances of JeecgBoot 3.9.0 in your environment using network scanning and application inventory tools
2. Disable or restrict access to the /sys/common/uploadImgByHttp endpoint immediately using WAF rules or network ACLs
3. Implement IP whitelisting for the uploadImgByHttp endpoint to trusted internal sources only
4. Monitor all requests to this endpoint for suspicious fileUrl parameters
COMPENSATING CONTROLS:
5. Deploy Web Application Firewall (WAF) rules to block requests containing suspicious URLs (internal IPs, localhost, cloud metadata endpoints like 169.254.169.254)
6. Implement egress filtering to prevent the server from making outbound HTTP requests to internal networks or cloud metadata services
7. Restrict outbound connectivity from JeecgBoot servers to only necessary external services
8. Implement network segmentation to isolate JeecgBoot instances from sensitive internal systems
DETECTION:
9. Monitor logs for POST requests to /sys/common/uploadImgByHttp with fileUrl parameters containing: 127.0.0.1, 192.168.*, 10.*, 172.16-31.*, localhost, 169.254.169.254
10. Alert on any outbound HTTP/HTTPS connections from JeecgBoot servers to internal IP ranges
11. Review application logs for error messages indicating failed internal resource access attempts
LONG-TERM:
12. Plan migration to patched JeecgBoot version when available or alternative framework
13. Conduct security code review of custom implementations using JeecgBoot
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع نسخ JeecgBoot 3.9.0 في بيئتك باستخدام أدوات المسح والجرد
2. تعطيل أو تقييد الوصول إلى نقطة النهاية /sys/common/uploadImgByHttp فوراً باستخدام قواعد WAF أو ACLs
3. تطبيق قائمة بيضاء للعناوين IP للنقطة النهائية من المصادر الداخلية الموثوقة فقط
4. مراقبة جميع الطلبات إلى هذه النقطة النهائية للكشف عن معاملات fileUrl المريبة
الضوابط البديلة:
5. نشر قواعد WAF لحظر الطلبات التي تحتوي على عناوين URL مريبة (عناوين IP داخلية، localhost، نقاط نهاية البيانات الوصفية السحابية)
6. تطبيق تصفية الخروج لمنع الخادم من إجراء طلبات HTTP الصادرة إلى الشبكات الداخلية
7. تقييد الاتصالية الصادرة من خوادم JeecgBoot إلى الخدمات الخارجية الضرورية فقط
8. تطبيق تقسيم الشبكة لعزل نسخ JeecgBoot عن الأنظمة الداخلية الحساسة
الكشف:
9. مراقبة السجلات للطلبات POST إلى /sys/common/uploadImgByHttp مع معاملات fileUrl تحتوي على عناوين IP داخلية
10. التنبيه على أي اتصالات HTTP/HTTPS صادرة من خوادم JeecgBoot إلى نطاقات IP داخلية
11. مراجعة سجلات التطبيق للرسائل التي تشير إلى محاولات الوصول الفاشلة للموارد الداخلية
المدى الطويل:
12. التخطيط للهجرة إلى نسخة JeecgBoot المصححة عند توفرها أو إطار عمل بديل
13. إجراء مراجعة أمان الكود للتطبيقات المخصصة التي تستخدم JeecgBoot
