[原文]Directory traversal vulnerability in the Web Calendaring server in Ipswitch Imail 8.13, and other versions before IMail Server 8.2 Hotfix 2, allows remote attackers to read arbitrary files via "..\" (dot dot backslash) sequences in the query string argument in a GET request to a non-existent .jsp file.


[CNNVD]Ipswitch IMail IMAP SELECT命令拒绝服务漏洞(CNNVD-200505-1204)

        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 05.24.05-4 - Remote exploitation of a directory traversal vulnerability in Ipswitch Inc.'s Imail Web Calendaring server allows attackers to read arbitrary files with System privileges. Version 8.13 is confirmed vulnerable. Earlier versions may be susceptible as well.

Ipswitch IMail Web Calendaring Arbitrary File Read Vulnerability

iDEFENSE Security Advisory 05.24.05
www.idefense.com/application/poi/display?id=242&type=vulnerabilities
May 24, 2005

I. BACKGROUND

Ipswitch Collaboration Suite (ICS) is a comprehensive communication and 
collaboration solution for Microsoft Windows with a customer base of 
over 53 million users. More information is available on the vendor's 
website:

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

II. DESCRIPTION

Remote exploitation of a directory traversal vulnerability in Ipswitch 
Inc.'s Imail Web Calendaring server allows attackers to read arbitrary 
files with System privileges. 

The problem specifically exists because of a flaw in the handling of 
requests for nonexistent javascript (jsp) files. By requesting a 
nonexistent jsp file followed by a question mark, several sequences of 
"..\" and then the path to a file on the system, an attacker can read 
arbitrary files remotely without any authentication. 

The following query demonstrates how the system's boot.ini file may be 
retrieved: 

GET /bla.jsp?\..\..\..\..\..\..\..\..\..\..\boot.ini HTTP/1.0
Connection: Close
Host: example.com
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
Pragma: no-cache 

III. ANALYSIS

Successful exploitation allows remote attackers to retrieve arbitrary 
files from the target host. Exploitation does not require authentication

and does not require exploit code, as a user can simply type the 
malicious query in a web browser.

IV. DETECTION

iDEFENSE has confirmed the existence of this vulnerability in the latest

version of Ipswitch IMAIL, version 8.13. It is suspected that earlier 
versions are also vulnerable.

V. WORKAROUND

Limit access to the Web Calandaring server by allowing only trusted 
hosts to access TCP port 8484, the default port for Web Calandaring. If 
the Web Calandaring service is not required, disable it entirely.

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-2005-1252 to this issue. This is a candidate for inclusion in
the CVE list (http://cve.mitre.org), which standardizes names for
security problems.
