🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
1. Monitor the GitHub repository for updates. 2. Apply any security patches when released. 3. Restart the application after patching.
🔧 Temporary Workarounds
Implement authorization middleware
allAdd proper authorization checks before notice management functions execute
# Requires code modification in NoticeController.java
Disable notice management endpoints
linuxTemporarily block access to /notice/* endpoints via web application firewall or reverse proxy
# Example nginx location block:
location ~ ^/notice/ { deny all; }
🧯 If You Can't Patch
- Implement network segmentation to restrict access to the warehouse application
- Deploy a web application firewall with rules to detect and block unauthorized notice management requests
🔍 How to Verify
Check if Vulnerable:
Check if your codebase includes the vulnerable commit aaf29962ba407d22d991781de28796ee7b4670e4 or earlier versions of NoticeController.javaCheck Version:
git log --oneline | head -20Verify Fix Applied:
Verify that authorization checks have been added to addNotice, updateNotice, deleteNotice, and batchDeleteNotice methods📡 Detection & Monitoring
Log Indicators:
- Unauthorized POST/PUT/DELETE requests to /notice/* endpoints
- Notice creation/modification/deletion from unexpected user accounts or IPs
Network Indicators:
- HTTP requests to notice management endpoints without proper authentication headers
- Unusual patterns of notice-related API calls
SIEM Query:
source="application.log" AND (uri_path="/notice/add" OR uri_path="/notice/update" OR uri_path="/notice/delete") AND NOT user_role="admin"
