Axigen Mail Server is a small Mail Server.

2) Pass the "fileName" parameter to index. note: If you set "page" to "vlf" and "action" to "delete", you can delete an object by means of directory traversal, this vulnerability can cause leakage and download of arbitrary files.

To successfully exploit this vulnerability, you must access the "Logging" module.
