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 auxiliary/gather/f5_bigip_cookie_disclosure
msf auxiliary(f5_bigip_cookie_disclosure) > show actions
msf auxiliary(f5_bigip_cookie_disclosure) > set ACTION < action-name >
msf auxiliary(f5_bigip_cookie_disclosure) > show options
    ...show and set options...
msf auxiliary(f5_bigip_cookie_disclosure) > 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.
