CVE-2025-66410
📋 TL;DR
CVE-2025-66410 is a path traversal vulnerability in gin-vue-admin that allows attackers to delete arbitrary files and folders on the server by controlling the 'FileMd5' parameter. This affects all deployments running version 2.8.6 or earlier of the gin-vue-admin backstage management system, potentially leading to data loss, service disruption, or complete system compromise.
💻 Affected Systems

📦 What is this software?
Gin Vue Admin by Gin Vue Admin Project
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through deletion of critical system files, leading to permanent data loss, service unavailability, or operating system corruption requiring full system restoration.
Likely Case
Targeted deletion of application files, configuration files, or user data causing service disruption, data loss, and potential privilege escalation through manipulation of system components.
If Mitigated
Limited impact to non-critical files if proper file permissions and access controls are in place, though application functionality may still be disrupted.
🎯 Exploit Status
Exploitation requires access to the file management functionality but is straightforward once authenticated. The advisory includes technical details that could facilitate exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.8.7 or later
Vendor Advisory: https://github.com/flipped-aurora/gin-vue-admin/security/advisories/GHSA-jrhg-82w2-vvj7
Restart Required: Yes
Instructions:
1. Update to gin-vue-admin version 2.8.7 or later. 2. Apply the security patch from commit ee8d8d7e04d9c38a35a6969f20e75213e84f57c6. 3. Restart the application service. 4. Verify the fix by testing file deletion functionality.
🔧 Temporary Workarounds
Disable file management functionality
allTemporarily disable or restrict access to the vulnerable file management endpoints until patching can be completed.
# Configure web server or application firewall to block access to file management endpoints
# Example for nginx: location ~* /api/file { deny all; }
Implement strict file permission controls
linuxSet restrictive permissions on critical directories and files to limit potential damage from exploitation.
# Set appropriate ownership and permissions
chown root:root /path/to/critical/directories
chmod 700 /path/to/critical/directories
🧯 If You Can't Patch
- Implement strict network segmentation to isolate gin-vue-admin instances from critical systems
- Deploy Web Application Firewall (WAF) with path traversal protection rules
🔍 How to Verify
Check if Vulnerable:
Check if running gin-vue-admin version 2.8.6 or earlier. Review application logs for unauthorized file deletion attempts or suspicious file management requests.Check Version:
Check package.json or application configuration for version information, or use: grep -r "version" /path/to/gin-vue-admin/Verify Fix Applied:
Verify version is 2.8.7 or later. Test file deletion functionality with path traversal attempts to confirm they are properly blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual file deletion requests
- Requests with suspicious FileMd5 parameters containing path traversal sequences (../, ..\)
- Multiple failed file operations from single source
Network Indicators:
- HTTP requests to file management endpoints with unusual parameters
- Burst of DELETE requests to file API endpoints
SIEM Query:
source="gin-vue-admin" AND (method="DELETE" OR uri_path="/api/file") AND (param="FileMd5" AND value="*../*")
