BigAnt Server DUPF Command Arbitrary File Upload



This exploits an arbitrary file upload vulnerability in BigAnt Server 2.97 SP7. A lack of authentication allows to make unauthenticated file uploads through a DUPF command. Additionally the filename option in the same command can be used to launch a directory traversal attack and achieve arbitrary file upload. The module uses the Windows Management Instrumentation service to execute an arbitrary payload on vulnerable installations of BigAnt on Windows XP and 2003. It has been successfully tested on BigAnt Server 2.97 SP7 over Windows XP SP3 and 2003 SP2.

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/misc/bigant_server_dupf_upload
msf exploit(bigant_server_dupf_upload) > show targets
msf exploit(bigant_server_dupf_upload) > set TARGET < target-id >
msf exploit(bigant_server_dupf_upload) > show options
    ...show and set options...
msf exploit(bigant_server_dupf_upload) > 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.
