## Overview

rConfig before 8.2.13 contains a path traversal vulnerability that allows authenticated attackers to read arbitrary files by supplying unsanitized directory traversal sequences in the filename GET parameter of the download_export() method. Attackers can craft requests with ../ sequences to escape the exports base directory and access sensitive files readable by the web server process, including application environment files containing encryption keys, database credentials, and mail configuration.
