Path Traversal occurrences in Rconfig
rConfig 3.9.6 is affected by a Local File Disclosure vulnerability. An authenticated user may successfully download any file on the server. (2021-10-11, CVE-2021-29006)
rConfig 3.9.5 could allow a remote authenticated attacker to traverse directories on the system. An attacker could send a crafted request to the ajaxGetFileByPath.php script containing hexadecimal encoded "dot dot" sequences (%2f..%2f) in the path parameter to view arbitrary files on the system. (2020-07-28, CVE-2020-15712)
** DISPUTED ** A downloadFile.php download_file path traversal vulnerability in rConfig through 3.9.3 allows attackers to list files in arbitrary folders and potentially download files. NOTE: the discoverer later reported that there was not a "fully working exploit." (2019-11-28, CVE-2019-19372)
Why Path Traversal can be dangerous
Relative Path Confusion means that your web server is configured to serve responses to ambiguous URLs. This configuration can possibly cause confusion about the correct relative path for the URL. It is also an issue of resources, such as images, styles etc., which are specified in the response using relative path, not the absolute URL.
If the web browser permits to parse "cross-content" response, the attacker may be able to fool the web browser into interpreting HTML into other content types, which can then lead to a cross site scripting attack (link do XSS).
