Hi again.
I was testing --os-bof in a box with xp_cmdshell and ... :

[16:20:10] [INFO] checking if xp_cmdshell extended procedure is available,

I tried other encoding types too, and with shell payload.
There's no error, but there is a "unexpectedly quit" .. Is this a bug\error
in code, or the server is really patched?

Thanks alot,
Best Regards,
Gabriel.
