Category:   Application (E-mail Server)  >   IMail Server Vendors:   Ipswitch
IMail Server Input Validation Flaw Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1030335
SecurityTracker URL:  http://securitytracker.com/id/1030335
CVE Reference:   CVE-2014-3878   (Links to External Site)
Updated:  Jun 11 2014
Original Entry Date:  Jun 5 2014
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 12.3.x, 12.4 prior to 12.4.1.15
Description:   A vulnerability was reported in IMail Server. A remote user can conduct cross-site scripting attacks.

Several scripts do not properly filter HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the IMail Server 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.

The new contacts, adding group, calendar, and task sections are affected.

Peru (GoSecure!) reported this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the IMail Server 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.
Solution:   No solution was available at the time of this entry.
Vendor URL:  www.imailserver.com/ (Links to External Site)
Cause:   Input validation error
Underlying OS:  Windows (2000), Windows (2003)

Subject:  [FD] IPSwitch IMail Server WEB client 12.4 persistent XSS

# Exploit Title: IPSwitch IMail Server WEB client 12.4 persistent XSS

# Date: 3 june 2014

# Exploit Author: Peru (GoSecure!)

# Vendor Homepage: www.ipswitch.com

# Software Link: http://www.imailserver.com/try/

# Version: Tested on 12.3 and 12.4 before 12.4.1.15

# Tested on: WindowsServer2008R2 STD SP1

# CVE : 2014-3878 (Calendar section)

 

Four injection points were useful to create a persistent Cross Site
Scripting. All the injections are reached using default Web Client
interface, but the Web Client Lite seems to be not vulnerable to these
tests. 

 

1. Contacts section: 

A persistent XSS can be reached adding a new contact with a specific string
in the Name field and whatever image: 

 

PoC string: 

G<IFRAME SRC="javascript:alert('XSS');"></IFRAME>S! 

 

When the contact is saved and on mouse over the picture the Name is been
displayed in a bubble activating the JS. 

 

2. Contacts section: 

A vulnerability can also be reached in the Adding Group task. 

 

PoC string: 

<iframe src="http://www.google.it" height=500 width=500 frameborder=1
align=center></iframe> 

 

3. Calendar section: 

A persistent XSS can be reached adding a new event in the Calendar; this
event can be spread adding the Meeting Request option. 

Since, using this injection point, the XSS can be spread to other users,
this is the most dangerous of the four and can be used to spoofing sessions
and therefore compromising the attacked users account. 

 

The JavaScript is executed simply viewing the calendar or when the Reminder
pops up. 

 

PoC string: 

GS!<IFRAME SRC="javascript:alert('XSS');"></IFRAME> 

 

4.Task section: 

In a similar way also the tasks are vulnerable to persistent XXS. 

 

PoC string: 

<iframe src=http://www.mysite.com/remote/xss_h.html> 

 

Bye

Peru
