This module exploits a flaw in the McAfee Subscription Manager ActiveX control. Due to an unsafe use of vsprintf, it is possible to trigger a stack buffer overflow by passing a large string to one of the COM-exposed routines, such as IsAppExpired. This vulnerability was discovered by Karl Lynn of eEye.

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