FreeFloat FTP Server Arbitrary File Upload



This module abuses multiple issues in FreeFloat: 1. No credential is actually needed to login; 2. User's default path is in C:\, and this cannot be changed; 3. User can write to anywhere on the server's file system. As a result of these poor implementations, a malicious user can just log in and then upload files, and let WMI (Management Instrumentation service) to execute the payload uploaded.

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 exploit/windows/ftp/freefloatftp_wbem
msf exploit(freefloatftp_wbem) > show targets
msf exploit(freefloatftp_wbem) > set TARGET < target-id >
msf exploit(freefloatftp_wbem) > show options
    ...show and set options...
msf exploit(freefloatftp_wbem) > exploit

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.
