[原文]Stack-based buffer overflow in the IMAP server for Ipswitch IMail 8.12 and 8.13, and other versions before IMail Server 8.2 Hotfix 2, allows remote authenticated users to cause a denial of service (crash) via a SELECT command with a large argument.


[CNNVD]Ipswitch IMail IMAP SELECT命令拒绝服务漏洞(CNNVD-200505-1195)

        Ipswitch IMail server是基于Windows的通讯和协作解决方案。
        Ipswitch Inc的Imail IMAP server中存在远程拒绝服务漏洞,攻击者可以利用这个漏洞导致目标服务崩溃。
        漏洞起因是处理SELECT命令的超长参数。如果攻击者能够提供长度大约为260个字节的字符串的话,就可能触发栈溢出,导致守护程序退出。但无法再进一步利用这个漏洞。

iDEFENSE Security Advisory 05.24.05-5 - Remote exploitation of a denial of service vulnerability in Ipswitch Inc.'s Imail IMAP server allows attackers to crash the target service thereby preventing legitimate usage. Version 8.13 and 8.12 are confirmed vulnerable. Earlier versions may be susceptible as well.

Ipswitch IMail IMAP SELECT Command DoS Vulnerability

iDEFENSE Security Advisory 05.24.05
www.idefense.com/application/poi/display?id=241&type=vulnerabilities
May 24, 2005

I. BACKGROUND

Ipswitch IMail server is a Windows based messaging solution with a
customer base of over 53 million users. More information about the
application is available at:

    http://www.ipswitch.com/products/IMail_Server/index.html.

II. DESCRIPTION

Remote exploitation of a denial of service vulnerability in Ipswitch
Inc.'s Imail IMAP server allows attackers to crash the target service
thereby preventing legitimate usage.

The problem specifically exists in the handling of long arguments to the
SELECT command. When a string approximately 260 bytes in size is
supplied a stack-based buffer overflow occurs that results in an
unhandled access violation forcing the daemon to exit. The issue is not
believed to be further exploitable.

III. ANALYSIS

Successful exploitation allows remote to crash vulnerable IMAP servers
and thereby prevent legitimate usage. The SELECT command is only
available post authentication and therefore valid credentials are
required to exploit this vulnerability

IV. DETECTION

iDEFENSE has confirmed the existence of this vulnerability in the latest
version of Ipswitch IMAIL, version 8.13. Version 8.12 is also confirmed
as vulnerable. It is suspected that earlier versions are vulnerable as
well.

V. WORKAROUND

As this vulnerability is exploited after authentication occurs, ensuring

that only trusted users have accounts can mitigate the risk somwhat. As 
a more effective workaround, consider limiting access to the IMAP server

by filtering TCP port 143. If possible, consider disabling IMAP and 
forcing users to use POP3.

VI. VENDOR RESPONSE

The vendor has released the following patch to fix this vulnerability:

ftp://ftp.ipswitch.com/Ipswitch/Product_Support/IMail/imail82hf2.exe

The associated vendor advisory can be found at:

http://www.ipswitch.com/support/imail/releases/imail_professional/im82hf
2.html

VII. CVE INFORMATION

The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CAN-2005-1254 to this issue. This is a candidate for inclusion in
the CVE list (http://cve.mitre.org), which standardizes names for
security problems.

VIII. DISCLOSURE TIMELINE

04/15/2005  Initial vendor notification
05/10/2005  Initial vendor response

Ipswitch IMail IMAP SELECT Command Remote DoS
Remote / Network Access Denial of Service
Loss of Availability
Exploit Unknown

- 漏洞描述

A remote overflow exists in IMail Server. The IMAP service (IMAP4D32.EXE) fails to perform proper bounds checking resulting in a buffer overflow. By passing an overly long string to the 'SELECT' command, a remote attacker can cause the IMAP service to crash resulting in a loss of availability.
