Executive Summary

This vulnerability is a path traversal flaw in the liketrek TREK software up to version 3.0.22. It exists in the Public Journey Photo Proxy component, specifically in the server/src/nest/journey/journey-public.controller.ts file. An attacker can remotely manipulate file paths to access unauthorized directories.

Detection Guidance

To detect this vulnerability, check if your TREK application version is below 3.1.0. Inspect server logs for unusual access patterns to /uploads/journey or sibling directories. Look for requests containing encoded path traversal sequences like ..%2Ffiles%2F or ../files/. Test with crafted asset IDs to see if unauthorized file access occurs.

Impact Analysis

An attacker could exploit this to read sensitive files outside the intended directory, potentially exposing confidential data. The high attack complexity and difficulty reduce risk but do not eliminate it. Upgrading to version 3.1.0 or later is recommended to mitigate the issue.

Compliance Impact

This vulnerability could lead to unauthorized data access, violating GDPR (data protection) and HIPAA (health information privacy) by exposing sensitive personal or medical data. Compliance may be compromised if exploited, requiring remediation to avoid penalties.

Mitigation Strategies

Upgrade the liketrek TREK component to version 3.1.0 or later to address the path traversal vulnerability.
