Path Traversal occurrences in Remote Access Server
All versions of ETIC Telecom Remote Access Server (RAS) 4.5.0 and prior’s application programmable interface (API) is vulnerable to directory traversal through several different methods. This could allow an attacker to read sensitive files from the server, including SSH private keys, passwords, scripts, python objects, database files, and more. (2022-11-10, CVE-2022-41607)
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).
