It is possible for an attacker to traverse the web folders of a Savant HTTP Server. Submitting a URL referring to a known directory or file, and appended with specific unicode characters, will disclose the contents of the requested resource. The unicode character in question is '%2f..'. This vulnerability could allow the reading of files on the target system.
