This module uses a valid administrator username and password to execute an arbitrary command on one or more hosts, using a similar technique than the "psexec" utility provided by SysInternals. Daisy chaining commands with '&' does not work and users shouldn't try it. This module is useful because it doesn't need to upload any binaries to the target machine.
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use auxiliary/admin/smb/psexec_command
msf auxiliary(psexec_command) > show actions
...actions...
msf auxiliary(psexec_command) > set ACTION < action-name >
msf auxiliary(psexec_command) > show options
...show and set options...
msf auxiliary(psexec_command) > 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.
