CVE-2025-6776 is a critical Path Traversal vulnerability discovered in xiaoyunjie's openvpn-cms-flask, affecting versions from 1.2.0 through 1.2.7. This flaw allows attackers to potentially access sensitive files on the server by manipulating file upload parameters. A fix is available in version 1.2.8, and users are strongly advised to upgrade immediately.
An attacker can exploit this Path Traversal vulnerability by manipulating the 'image' parameter during file uploads. This manipulation allows them to bypass security controls and access arbitrary files on the server's file system. The potential impact includes unauthorized access to configuration files, source code, or other sensitive data. Successful exploitation could lead to data breaches, system compromise, and potential lateral movement within the network if the server has access to other resources. The ability to read arbitrary files significantly expands the attack surface.
This vulnerability has been publicly disclosed, increasing the likelihood of exploitation. While no active campaigns have been definitively linked to CVE-2025-6776, the availability of a public exploit significantly raises the risk. The CVSS score of 7.3 (HIGH) reflects the potential impact and ease of exploitation. It is not currently listed on CISA KEV.
Organizations utilizing openvpn-cms-flask in their infrastructure, particularly those with publicly accessible file upload endpoints, are at risk. Environments with weak file upload validation or inadequate WAF protection are especially vulnerable. Shared hosting environments where multiple users share the same server resources are also at increased risk.
• python: Monitor file upload endpoints for unusual file extensions or paths.
# Example: Check for suspicious characters in uploaded filenames
import re
filename = request.files['image'].filename
if re.search(r'../', filename):
print('Potential path traversal attempt!')• generic web: Check access and error logs for requests containing path traversal sequences (e.g., ../).
• generic web: Use curl to test file upload endpoints with crafted filenames containing path traversal sequences.

The primary mitigation for CVE-2025-6776 is to immediately upgrade openvpn-cms-flask to version 1.2.8. This version includes a patch (commit e23559b98c8ea2957f09978c29f4e512ba789eb6) that addresses the vulnerability. If upgrading is not immediately feasible, consider implementing temporary workarounds such as restricting file upload locations to a tightly controlled directory and implementing strict file type validation. Review and harden file upload configurations to prevent similar vulnerabilities. After upgrading, confirm the fix by attempting a file upload with a path traversal payload (e.g., '../etc/passwd') and verifying that access is denied.
Actualice openvpn-cms-flask a la versión 1.2.8 o superior. Esta versión contiene una corrección para la vulnerabilidad de path traversal en la función Upload del archivo controller.py. La actualización evitará que atacantes remotos manipulen el argumento 'image' para acceder a archivos no autorizados.
