CVE-2025-66410 is a path traversal vulnerability classified under CWE-22 affecting the flipped-aurora gin-vue-admin backstage management system, specifically versions 2.8.6 and earlier. Gin-vue-admin is a web-based administrative platform built on Vue.js and the Gin web framework, commonly used for backend management. The vulnerability arises from improper validation of the 'FileMd5' parameter, which attackers can manipulate to traverse directories and delete arbitrary files or folders on the server. This lack of pathname restriction allows attackers to bypass intended file system boundaries, leading to unauthorized file deletions. Exploitation requires no authentication, user interaction, or privileges, and can be performed remotely over the network, increasing the attack surface. The impact includes potential denial of service due to deletion of critical files, loss of data integrity, and disruption of server operations. Although no public exploits have been reported yet, the high CVSS score of 8.7 reflects the ease of exploitation and significant impact. The vulnerability underscores the need for secure input validation, proper access controls, and patching in web management systems. No official patches are currently linked, so organizations must monitor vendor updates or apply custom mitigations.

For European organizations, this vulnerability poses a significant risk to the availability and integrity of backend management systems running gin-vue-admin. Successful exploitation can lead to deletion of critical configuration files, logs, or application data, causing service outages or operational disruptions. This is particularly impactful for sectors relying on gin-vue-admin for infrastructure management, such as finance, healthcare, government, and manufacturing. The ability to delete arbitrary files without authentication increases the threat level, as attackers can cause damage without needing insider access. Additionally, disruption of backend systems can cascade into broader IT service interruptions, affecting business continuity and compliance with data protection regulations like GDPR. The lack of known exploits currently provides a window for proactive defense, but the high severity score demands urgent attention. Organizations with exposed gin-vue-admin instances on public networks are especially vulnerable to remote attacks.

1. Immediately identify and inventory all gin-vue-admin instances within the organization, focusing on versions 2.8.6 and earlier. 2. Monitor the flipped-aurora project for official patches or security updates addressing CVE-2025-66410 and apply them promptly once available. 3. Implement strict input validation on the 'FileMd5' parameter to enforce whitelist checks and prevent directory traversal characters such as '../'. 4. Restrict file system permissions for the gin-vue-admin process to the minimum necessary, preventing deletion of critical system or application files. 5. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious path traversal attempts targeting the 'FileMd5' parameter. 6. Limit network exposure of gin-vue-admin interfaces by placing them behind VPNs or internal-only access controls. 7. Conduct regular backups of critical files and configurations to enable rapid recovery in case of deletion. 8. Implement continuous monitoring and alerting for unusual file deletion activities on servers hosting gin-vue-admin. 9. Educate development and operations teams on secure coding practices to prevent similar vulnerabilities in future releases.
