Executive Summary

This vulnerability is a path traversal flaw in PGYER Codefever, a self-hosted Git repository service. It exists in the _detail function of application/controllers/doc.php where the uri_string argument is improperly sanitized. Attackers can manipulate this to traverse directories and read files outside the intended documentation directory, including sensitive files like configuration files.

Detection Guidance

To detect this vulnerability, inspect the application's access logs for unusual URI patterns containing sequences like '....//' or excessive '../' segments. Check for unauthorized file reads in logs, especially for sensitive files such as database.php or env.yaml. Use tools like curl to test if the server returns contents of arbitrary files when sending crafted GET requests to the doc.php endpoint with traversal paths.

Impact Analysis

This vulnerability allows unauthenticated attackers to read arbitrary files on the server hosting Codefever. Sensitive files such as database credentials, configuration files, or other secrets could be exposed. Since Codefever is self-hosted, this could lead to data breaches, unauthorized access to repositories, or further compromise of the hosting server.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, which may violate compliance requirements under GDPR (data protection) and HIPAA (health information privacy). Exposure of personal or health data could result in legal penalties, fines, or reputational damage due to non-compliance with data protection regulations.

Mitigation Strategies

Apply the patch from commit e4433eee96883a222403854e8ac38b3146774a07 immediately. Update to the latest master branch of CodeFever to ensure the fix is applied. If updating is not possible, implement input sanitization to reject URI segments containing '..' or NUL bytes. Restrict file access permissions to the minimum required and monitor for suspicious file access patterns.
