FileZilla FTP Server Admin Interface Denial of Service



This module triggers a Denial of Service condition in the FileZilla FTP Server Administration Interface in versions 0.9.4d and earlier. By sending a procession of excessively long USER commands to the FTP Server, the Administration Interface (FileZilla Server Interface.exe) when running, will overwrite the stack with our string and generate an exception. The FileZilla FTP Server itself will continue functioning.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/dos/windows/ftp/filezilla_admin_user
msf auxiliary(filezilla_admin_user) > show actions
msf auxiliary(filezilla_admin_user) > set ACTION < action-name >
msf auxiliary(filezilla_admin_user) > show options
    ...show and set options...
msf auxiliary(filezilla_admin_user) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
