Module Overview

Name: FileZilla FTP Server Admin Interface Denial of Service
Module: auxiliary/dos/windows/ftp/filezilla_admin_user
Source code: modules/auxiliary/dos/windows/ftp/filezilla_admin_user.rb
Disclosure date: 2005-11-07
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2005-3589

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.
