This exploit gains remote code execution on Firefox 31-34 by abusing a bug in the XPConnect component and gaining a reference to the privileged chrome:// window. This exploit requires the user to click anywhere on the page to trigger the vulnerability.
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/multi/browser/firefox_proxy_prototype
msf exploit(firefox_proxy_prototype) > show targets
...targets...
msf exploit(firefox_proxy_prototype) > set TARGET < target-id >
msf exploit(firefox_proxy_prototype) > show options
...show and set options...
msf exploit(firefox_proxy_prototype) > 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.
