#It is possible to download any file on the Muster server by exploiting a vulnerability in the web server. By #using directory traversal characters (\..\..\) in the URL, it is possible to specify any file on the file #system to be served to the client. Exploitation of this vulnerability does not require authentication. The #table below includes an example HTTP Request that would allow the download of the “muster.db” SQLite database:

 

#Example of Malicious HTTP Request :
