This module exploits a vulnerability found on Firefox 17.0.6, specifically a use after free of a DocumentViewerImpl object, triggered via a specially crafted web page using onreadystatechange events and the window.stop() API, as exploited in the wild on 2013 August to target Tor Browser users.

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 exploit/windows/browser/mozilla_firefox_onreadystatechange
msf exploit(mozilla_firefox_onreadystatechange) > show targets
    ...targets...
msf exploit(mozilla_firefox_onreadystatechange) > set TARGET < target-id >
msf exploit(mozilla_firefox_onreadystatechange) > show options
    ...show and set options...
msf exploit(mozilla_firefox_onreadystatechange) > 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.
