Cartel security team has found a buffer overflow in the Cerberus FTP
which means that an attacker can execute a denial of service attack
against it.This attack will crash the server, without any error.
FTP service is then unavailable.


The binary exploit is given as a proof of concept.
It is for educational purpose only.
Cartel team can't be held responsible for anything you do
with this file.
The exploit file has been fully coded in Win32 assembly language.


220-Welcome to Cerberus FTP Server
220 Created by Grant Averett
USER [buffer]
PASS [anything]

[buffer] is aprox. 320 characters.


A good combination of the buffer and pass is needed in order to
crash the server.Passing only a BIG user won't crash anything.
