Description

A vulnerability within the VBoxGuest driver allows an attacker to inject memory they control into an arbitrary location they define. This can be used by an attacker to overwrite HalDispatchTable+0x4 and execute arbitrary code by subsequently calling NtQueryIntervalProfile on Windows XP SP3 systems. This has been tested with VBoxGuest Additions up to 4.3.10r93012.

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