Vulnerability Details:  
When exploited, this vulnerability allows an anonymous attacker to write files to specified locations on a user's system.  
  
The FTP client does not properly sanitise filenames containing directory traversal sequences that are received from an FTP server, for example  
file named as "..\..\..\..\..\..\..\somefile.exe".  
  
By tricking a user to download a directory from a malicious FTP server that contains files with backslash directory traversal sequences in their filenames,   
an attacker can potentially write files into a user's Startup folder to execute malicious code when the user logs on.
