Path Traversal occurrences in Web Proxy
There is a Directory Traversal vulnerability in Artica Proxy (4.30.000000 SP206 through SP255, and VMware appliance 4.30.000000 through SP273) via the filename parameter to /cgi-bin/main.cgi. (2022-04-25, CVE-2021-40680)
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).
