Overview
CVE-2025-66410 identifies a critical security vulnerability in Gin-Vue-Admin, a backstage management system built on Vue and Gin. This vulnerability, present in versions 2.8.6 and earlier, allows attackers to delete arbitrary files on the server. By manipulating the ‘FileMd5’ parameter, a malicious actor can potentially cause significant damage, leading to data loss and system unavailability.
Technical Details
The vulnerability stems from insufficient input validation and sanitization of the FileMd5 parameter used in file deletion operations. An attacker can craft a malicious request containing a manipulated FileMd5 value, pointing to any file or directory accessible to the application process. The lack of proper checks before executing the deletion operation allows the attacker to bypass intended security measures and delete sensitive system files or application data.
CVSS Analysis
Due to the information provided, a CVSS score is not available. However, considering the impact of arbitrary file deletion, this vulnerability would likely receive a high to critical CVSS score. The ability to delete any file on the server gives an attacker significant control and can lead to a complete compromise of the system’s integrity and availability. A CVSS score would need to be calculated based on factors such as attack vector, attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact.
Possible Impact
The impact of CVE-2025-66410 can be severe:
- Data Loss: Attackers can delete critical application data, leading to data corruption or loss.
- System Unavailability: Deletion of essential system files can render the Gin-Vue-Admin application or the entire server unusable.
- Privilege Escalation: In some scenarios, deleting specific files may allow attackers to escalate privileges or gain unauthorized access to the system.
- Denial of Service (DoS): By deleting critical application components, an attacker can effectively cause a denial of service for legitimate users.
Mitigation and Patch Steps
The most effective mitigation is to update Gin-Vue-Admin to a version that includes a fix for CVE-2025-66410. Refer to the official Gin-Vue-Admin repository or security advisories for the latest patched version.
If upgrading is not immediately possible, consider the following temporary mitigation measures:
- Input Validation: Implement strict input validation and sanitization for the
FileMd5parameter. Ensure that the value corresponds to a valid file within the intended directory. - Access Control: Enforce strict access control policies to limit the files and directories that the Gin-Vue-Admin application can access.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block malicious requests targeting the
FileMd5parameter. Configure the WAF to block requests containing suspicious characters or patterns in theFileMd5value.
