Path Traversal in Volmarg Personal Management System

Publication date: 2026-08-27

Last updated on: 2026-08-29

Assigner: VulnCheck

Description

Volmarg Personal Management System contains a path traversal vulnerability that allows authenticated attackers to read arbitrary files by supplying absolute filesystem paths to the GET /public/get-file/{path} endpoint. The path route parameter is passed directly to file_get_contents() without canonicalization against a permitted base directory, enabling attackers to retrieve sensitive files accessible to the PHP-FPM worker process without using directory traversal sequences.

Exploitability

CWE

KEV

CWE ID	Description
CWE-22	The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

Attack-Flow Graph

Executive Summary

This is a path traversal vulnerability in Volmarg Personal Management System where authenticated attackers can read arbitrary files by providing absolute filesystem paths to the GET /public/get-file/{path} endpoint. The path parameter is passed directly to file_get_contents() without validation against a restricted base directory, allowing access to sensitive files.

Detection Guidance

To detect this vulnerability, monitor HTTP requests to the GET /public/get-file/{path} endpoint. Check for requests with absolute filesystem paths (e.g., /etc/passwd) or unusual path parameters. Use tools like curl to test the endpoint with suspicious paths: curl http://target.com/public/get-file//etc/passwd. Inspect server logs for unauthorized file access attempts or errors from file_get_contents().

Enable application logging for the Personal Management System and review access logs for the /public/get-file endpoint. Look for requests with path parameters outside expected directories.

Impact Analysis

An attacker could exploit this to read sensitive files on the server, such as configuration files, user data, or credentials. This could lead to unauthorized access, data leaks, or further system compromise depending on the exposed files.

Compliance Impact

This vulnerability could violate compliance requirements like GDPR (data protection) or HIPAA (health information privacy) by exposing sensitive personal or health data. Organizations may face legal penalties, reputational damage, or mandatory breach notifications if exploited.

Mitigation Strategies

Immediately update the Volmarg Personal Management System to a patched version that includes directory validation for the /public/get-file endpoint. If no patch is available, restrict access to the endpoint via firewall rules or disable it temporarily.

Review and restrict permissions of the PHP-FPM worker process to limit file access. Implement strict input validation for the path parameter in the /public/get-file endpoint to ensure it only allows relative paths within permitted directories.
