CVE-2026-3026
📋 TL;DR
This CVE describes a Server-Side Request Forgery (SSRF) vulnerability in the UEditor component of erzhongxmu JEEWMS 3.7. Attackers can exploit the /plug-in/ueditor/jsp/getRemoteImage.jsp file by manipulating the 'upfile' parameter to make the server send unauthorized requests to internal or external systems. Organizations using JEEWMS 3.7 with the vulnerable UEditor component are affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could pivot to internal systems, access cloud metadata services, perform port scanning, or interact with internal APIs to steal sensitive data or achieve remote code execution.
Likely Case
Attackers will scan internal networks, access internal web applications, or interact with cloud metadata services to obtain credentials and escalate access.
If Mitigated
With proper network segmentation and egress filtering, impact is limited to the vulnerable server itself with minimal data exposure.
🎯 Exploit Status
Exploit has been publicly disclosed and requires minimal technical skill to execute.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider removing or disabling the UEditor component entirely.
🔧 Temporary Workarounds
Block access to vulnerable endpoint
allConfigure web server or WAF to block requests to /plug-in/ueditor/jsp/getRemoteImage.jsp
# Apache: RewriteRule ^/plug-in/ueditor/jsp/getRemoteImage\.jsp$ - [F]
# Nginx: location ~ ^/plug-in/ueditor/jsp/getRemoteImage\.jsp$ { return 403; }
Disable UEditor component
linuxRemove or disable the UEditor plugin from JEEWMS installation
rm -rf /path/to/jeewms/plug-in/ueditor/
# Or rename directory: mv /path/to/jeewms/plug-in/ueditor/ /path/to/jeewms/plug-in/ueditor_disabled/
🧯 If You Can't Patch
- Implement strict network egress filtering to prevent the server from making requests to internal systems
- Deploy a WAF with SSRF protection rules in front of the application
🔍 How to Verify
Check if Vulnerable:
Test if /plug-in/ueditor/jsp/getRemoteImage.jsp is accessible and accepts the 'upfile' parameterCheck Version:
Check JEEWMS version in admin panel or application filesVerify Fix Applied:
Verify the endpoint returns 403/404 or the UEditor directory no longer exists📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /plug-in/ueditor/jsp/getRemoteImage.jsp with 'upfile' parameter containing unusual URLs
- Outbound requests from server to internal IP ranges or metadata services
Network Indicators:
- Unusual outbound HTTP requests from the JEEWMS server to internal systems
SIEM Query:
source="web_server" AND uri="/plug-in/ueditor/jsp/getRemoteImage.jsp" AND query="*upfile=*"
