Path Traversal occurrences in Smartermail
SmarterTools SmarterMail 16.x before build 6985 allows directory traversal. An authenticated user could delete arbitrary files or could create files in new folders in arbitrary locations on the mail server. This could lead to command execution on the server for instance by putting files inside the web directories. (2019-04-24, CVE-2019-7213)
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).
