CVE-2025-66410 Overview
CVE-2025-66410 is an arbitrary file deletion vulnerability affecting Gin-vue-admin, a popular backstage management system built on Vue.js and the Gin web framework. The vulnerability allows unauthenticated attackers to delete any file or folder on the server by manipulating the FileMd5 parameter, potentially causing complete system unavailability or data loss.
Critical Impact
Remote attackers can delete arbitrary files and folders on affected servers without authentication, potentially leading to complete system compromise, data destruction, or denial of service.
Affected Products
- Gin-vue-admin versions 2.8.6 and earlier
- gin-vue-admin_project gin-vue-admin (all versions prior to patch)
- Systems running vulnerable Gin-vue-admin deployments

Technical Details for CVE-2025-66410
Vulnerability Analysis
This vulnerability is classified as CWE-22 (Path Traversal), a critical weakness that occurs when software fails to properly sanitize user-controlled input used in file system operations. In the case of Gin-vue-admin, the application accepts a FileMd5 parameter that is used to identify files for deletion operations. The parameter is not adequately validated, allowing attackers to craft malicious input that references files outside the intended directory scope.
The vulnerability is network-accessible and requires no authentication or user interaction to exploit, making it particularly dangerous for internet-facing deployments. Successful exploitation results in high integrity impact as attackers can delete critical system files, configuration data, or application components.
Root Cause
The root cause of CVE-2025-66410 lies in improper input validation of the FileMd5 parameter within the file management functionality. The application fails to implement adequate path sanitization or directory traversal protections, allowing attackers to specify arbitrary file paths. Without proper canonicalization of file paths or restriction to a designated upload directory, malicious actors can traverse the file system and target any file accessible to the application's process.
Attack Vector
The attack exploits the file deletion endpoint by manipulating the FileMd5 parameter. An attacker sends a crafted HTTP request to the vulnerable endpoint with a FileMd5 value containing path traversal sequences (such as ../) or absolute paths. The server processes this unsanitized input and performs the deletion operation on the specified file or directory. Since the vulnerability requires no authentication and is accessible over the network, any attacker with network access to the application can exploit it. The attack can be repeated to systematically delete multiple files, potentially rendering the entire server inoperable or destroying valuable data.
Detection Methods for CVE-2025-66410
Indicators of Compromise
- Unexpected file deletions in system logs, particularly configuration files or application binaries
- HTTP requests to file management endpoints containing path traversal patterns like ../ in the FileMd5 parameter
- Application errors or crashes due to missing critical files
- Audit logs showing deletion of files outside normal application directories
Detection Strategies
- Monitor web application logs for requests containing suspicious FileMd5 parameter values with directory traversal sequences
- Implement file integrity monitoring (FIM) to detect unauthorized deletions of critical system and application files
- Deploy web application firewall (WAF) rules to block path traversal patterns in request parameters
- Enable verbose logging on file operations within the Gin-vue-admin application
Monitoring Recommendations
- Configure real-time alerts for file system changes on production servers running Gin-vue-admin
- Implement SentinelOne endpoint detection to monitor for suspicious file deletion activity patterns
- Review access logs regularly for unusual patterns targeting file management API endpoints
- Set up baseline monitoring for critical system files and application directories
How to Mitigate CVE-2025-66410
Immediate Actions Required
- Update Gin-vue-admin to the patched version immediately by applying the security commit
- Restrict network access to Gin-vue-admin instances using firewall rules until patching is complete
- Implement WAF rules to block requests containing path traversal sequences in the FileMd5 parameter
- Review server file systems for evidence of unauthorized deletions
Patch Information
The Gin-vue-admin maintainers have released a security patch addressing this vulnerability. The fix is available in commit ee8d8d7e04d9c38a35a6969f20e75213e84f57c6 on the official GitHub repository. Organizations should update to the latest version that includes this patch. For detailed information about the vulnerability and remediation, refer to the GitHub Security Advisory GHSA-jrhg-82w2-vvj7 and the security patch commit.
Workarounds
- Deploy a reverse proxy or WAF in front of Gin-vue-admin to filter requests containing path traversal patterns
- Temporarily disable or restrict access to file management endpoints until the patch can be applied
- Implement application-level access controls to restrict file operations to authenticated administrative users only
- Run the Gin-vue-admin process with minimal file system permissions to limit the scope of potential file deletions
