Captaris Infinite Mobile Delivery Input Validation Hole Lets Remote Users Conduct Cross-Site Scripting Attacks and Determine the Installation Path
SecurityTracker Alert ID:  1013044
SecurityTracker URL:  http://securitytracker.com/id/1013044
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jan 31 2005
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 2.6
Description:   Steven from lovebug.org reported a vulnerability in Captaris Infinite Mobile Delivery. A remote user can conduct cross-site scripting attacks and can determine the installation path.

The webmail feature does not properly validate user-supplied input. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Infinite Mobile Delivery software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A demonstration exploit URL is of the following format:

http://[target]/username/[XSS]

The server will also disclose the installation path in response to the following type of URL containing a character that cannot be used as part of a Windows directory (folder) name:

http://[target]/username/Folder:?

The vendor was notified in November 2004.

The original advisory is available at:

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Infinite Mobile Delivery software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can determine the installation path.

Solution:   No solution was available at the time of this entry.

Subject:  XSS in Infinite Mobile Delivery v2.6 Webmail


Vendor:   Captaris, Inc.
Date:     January 29, 2005
Issue:    XSS in Infinite Mobile Delivery v2.6 Webmail
URL:      http://www.capataris.com
Advisory: http://www.lovebug.org/imd_advisory.txt
 

Issue:
 
The webmail portion of the latest (and final) release of Infinite Mobile Delivery 
contains a Cross Site Scripting vulnerability.  In addition to the XSS, an even smaller 
issue exists where a user can determine the installation path of the client and where 
e-mails are stored.
 
A user once logged in can simply start writing scripting immediately after their user 
name and it will be executed within the browser.
 
---
 
Example: http://www-webmailusersite-com/username/[XSS]
 
The server will respond with:
 
Unable to parse request for user blah:
[XSS]
 
---
 
Also, the server will return the installation path if an illegal windows folder 
character or name is entered after 'Folder:' - For example, Windows does not let you 
have folders containing < > * | : \ / ? or com1, com2, etc.
 
Example: http://www-webmailusersite-com/username/Folder:?
 
The server will respond with:
 
Error creating file: [drive letter]:\file's\path\USERS\username\?.IDX
 

---
 

Solutions:
 
I am not aware of any solutions at this time.
 

Vendor Response:
 
The vendor was notified of the issue in November 2004.  They also told me that Captaris 
is no longer developing Infinite Mobile Delivery and that there probably won't be any 
changs implemented.  To the best of my knowledge there will be no further releases and 
there is no fix available.
 
Credits:
 
The best University in Virginia (Virginia Tech) for providing me education for the past 
3.5 years and for having so much terrible cold weather which has given me time to write 
this up.
