📄 Description (English)

A vulnerability was identified in itwanger paicoding 1.0.0/1.0.1/1.0.2/1.0.3. The impacted element is the function Save of the file paicoding-web/src/main/java/com/github/paicoding/forum/web/common/image/rest/ImageRestController.java of the component Image Save Endpoint. Such manipulation of the argument img leads to server-side request forgery. The attack may be launched remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

🤖 AI Executive Summary

A Server-Side Request Forgery (SSRF) vulnerability exists in itwanger paicoding versions 1.0.0 through 1.0.3 in the Image Save Endpoint, allowing remote attackers to manipulate the 'img' parameter to perform unauthorized requests. With a CVSS score of 6.3 and publicly available exploits, this poses a moderate risk to organizations using affected versions. No patch is currently available from the vendor, requiring immediate compensating controls.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: May 17, 2026 04:33
🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using paicoding for internal knowledge management, community forums, or content management systems are at risk. Most vulnerable sectors include: Government agencies (NCA, CITC) using paicoding for internal portals; Educational institutions and research centers; Technology companies and startups; Media and publishing organizations. The SSRF vulnerability could allow attackers to access internal resources, scan internal networks, or pivot to backend systems, potentially compromising sensitive government or business data.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Inventory all systems running paicoding versions 1.0.0-1.0.3 across your organization
2. Isolate affected instances from production if possible or restrict network access
3. Implement Web Application Firewall (WAF) rules to block suspicious image upload requests

COMPENSATING CONTROLS (until patch available):
1. Implement strict input validation on the 'img' parameter - whitelist only allowed image sources and domains
2. Disable or restrict the Image Save Endpoint functionality if not critical
3. Implement network segmentation to prevent SSRF from reaching internal resources
4. Deploy egress filtering to block outbound requests to internal IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)
5. Monitor and log all image upload requests for suspicious patterns

DETECTION RULES:
1. Alert on requests to ImageRestController with 'img' parameter containing: file://, http://localhost, http://127.0.0.1, internal IP addresses
2. Monitor for unusual outbound connections from paicoding application server
3. Log and alert on image save endpoint requests with non-standard image URLs
4. Track failed image processing attempts that may indicate SSRF probing

PATCHING STRATEGY:
1. Contact vendor for security update timeline
2. Evaluate alternative solutions or forks with security patches
3. Plan migration to patched version immediately upon availability
4. Consider upgrading to versions beyond 1.0.3 if available
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع الأنظمة التي تقوم بتشغيل إصدارات paicoding 1.0.0-1.0.3 عبر مؤسستك
2. عزل الحالات المتأثرة عن الإنتاج إن أمكن أو تقييد الوصول إلى الشبكة
3. تطبيق قواعد جدار حماية تطبيقات الويب (WAF) لحجب طلبات تحميل الصور المريبة

الضوابط التعويضية (حتى توفر التصحيح):
1. تطبيق التحقق الصارم من صحة المدخلات على معامل 'img' - قائمة بيضاء فقط للمصادر والنطاقات المسموحة
2. تعطيل أو تقييد وظيفة نقطة نهاية حفظ الصور إذا لم تكن حرجة
3. تطبيق تقسيم الشبكة لمنع SSRF من الوصول إلى الموارد الداخلية
4. نشر تصفية الخروج لحجب الطلبات الصادرة إلى نطاقات IP الداخلية
5. مراقبة وتسجيل جميع طلبات تحميل الصور للأنماط المريبة

قواعد الكشف:
1. تنبيه على الطلبات إلى ImageRestController مع معامل 'img' يحتوي على: file://, http://localhost, http://127.0.0.1, عناوين IP الداخلية
2. مراقبة الاتصالات الصادرة غير العادية من خادم تطبيق paicoding
3. تسجيل والتنبيه على طلبات نقطة نهاية حفظ الصور مع عناوين URL صور غير قياسية
4. تتبع محاولات معالجة الصور الفاشلة التي قد تشير إلى اختبار SSRF

استراتيجية التصحيح:
1. اتصل بالبائع للحصول على جدول زمني لتحديث الأمان
2. تقييم الحلول البديلة أو الفروع التي تحتوي على تصحيحات أمنية
3. التخطيط للترقية إلى الإصدار المصحح فور توفره
4. النظر في الترقية إلى إصدارات تتجاوز 1.0.3 إذا كانت متاحة
