Description

This module exploits a stack buffer overflow in the FutureSoft TFTP Server
2000 product. By sending an overly long transfer-mode string, we were able
to overwrite both the SEH and the saved EIP. A subsequent write-exception
that will occur allows the transferring of execution to our shellcode
via the overwritten SEH. This module has been tested against Windows
2000 Professional and for some reason does not seem to work against
Windows 2000 Server (could not trigger the overflow at all).
