Safari for Windows, 0day exploit in 2 hours
http://larholm.com/2007/06/12/safari-for-windows-0day-exploit-in-2-hours/
By Thor Larholm
The below PoC exploit will exploit Safari by bouncing through Firefox
via the Gopher protocol, passing on unfiltered input for the -chrome
argument that Firefox exposes. When it has done this it will launch
C:WindowsSystem32cmd.exe with any arguments that have been specified
in the call to the process.run method.
It is important to know that, even though this PoC exploit uses Firefox,
the actual vulnerability is within the lack of input validation for the
command line arguments handed to the various URL protocol handlers on
your machine. As such, there are a lot of different attack vectors for
this vulnerability, I simply chose Firefox and the Gopher URL protocol
because I was familiar with these.
I hope you enjoyed the fruits of my 2 hours of labour. Please feel free
to add my RSS feed to your reader and come back again tomorrow or next
week for a fresh batch of 0day vulnerabilities :)
Cheers Thor Larholm
