[原文]Buffer overflow in SH39 MailServer 1.21 and earlier allows remote attackers to cause a denial of service, and possibly execute arbitrary code, via a long command to the SMTP port.


[CNNVD]SH39 MailServer拒绝服务漏洞(CNNVD-200208-236)

        
        SH39 MailServer是种微软Windows环境下的SMTP/POP3服务软件
        当25/TCP接收到大约2500个字符时,MailServer崩溃。在Unix系统上做如下测试:
        $ BUF=`perl -e '{print "A"x5000}'`
        $ echo helo $BUF | nc 25
        如果对端是Windows XP系统,你会看到MailServer报错,然后崩溃。如果对端是2K,MailServer不会报错,仅仅是停止响应,套接字关闭。无论如何,都需要重启MailServer才能恢复正常。
        根据现象来看,很可能是一次缓冲区溢出。一般情况下,MailServer以系统管理员权限运行。所以潜在允许远程执行攻击者提交的任意指令。

- 漏洞描述

A remote overflow exists in SH39 MailServer. The application fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted request to port 25 containing 2,500 or more characters, a remote attacker can cause the application to crash resulting in a loss of availability for the service.

- 漏洞讨论

MailServer by SH39 is an SMTP/POP3 server for Microsoft Windows environments.

Reportedly, connecting to port 25 on a MailServer host, and submitting an unusual amount of arbitrary data could initiate a denial of service condition.

This issue may be the result of an unchecked buffer. If this is the case, there is a possibility that arbitrary code may be executed on the vulnerable target. However, this has not yet been confirmed.

- 漏洞利用

No exploit code required.

- 解决方案

Reportedly, MailServer version 1.2.2 addresses this issue:


SH39 MailServer 1.2.1
