Accessing Vulnerability

IEXPLORE.EXE file version 6.0.2900.2180
MSHTML.DLL file version 6.00.2800.1400
Microsoft Windows XP Home SP2

[Discussion]Recently, a security professional aliased http-equiv ( found a vulnerability in Microsoft's new Service Pack (SP2). What was required to compromise the victim's machine was the dragging of an specially-crafted into a folderview window, and then the clicking of a button. LongNameVuln is a more efficient way of acheiving this common goal of compromising the system. It removes the extra step of having to click a button in order to access a page on the local machine. It can be done easily. Using the Related Topics command of Microsoft's Help ActiveX Control, any page can be loaded into a target frame. Unfortuneatly, only addresses that actually point to a location can be used. This does not include protocols such as javascript and vbscript. However, we can still break out of the Internet Zone and open up a page in the local zone. That is what this vulnerability achieves.

The example shows the picture of a garden which includes a carrot. Dragging the carrot to the bottom frame in the browser (set up to be the outside of the garden) will copy a file to PCHealth directory in C:\windows, which will then be launched, creating another file in the same directory called Greyhats.hta, which must be launched manually. The directory could easily be changed to shell:startup, however this is not necissary for this example. This is the same payload as given in NoCeegar on because my server doesn't have the capabilities to host the payload file like does :).
