paBox 'text' Variable Lets Remote Users Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1013363
SecurityTracker URL:  http://securitytracker.com/id/1013363
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Mar 3 2005
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 1.6
Description:   A vulnerability was reported in paBox. A remote user can conduct cross-site scripting attacks.

A remote user can submit specially crafted text with a hidden POST variable set to 'text'. When the text is viewed by a target user, arbitrary scripting code will be executed by the target user's browser. The code will originate from the site running the paBox 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.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the paBox 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.

Subject:  [XSS] paBox 1.6




Just wanted to let it be known seeing as i havent seen any info on this yet, ive discovered a cross scripting problem in PABox 1.6
 

http://phpnuke.org/modules.php?name=News&file=article&sid=5065

they give a demo page of pabox there.  if you take the default form used for the shoutbox, there are always two parameters marked
 as hidden:

<input type="hidden" name="date"...
and
<input type="hidden" name="time"...


you can easily extract the form from anysite's pabox and change the date value to "text" and inject scripting code into it.. for example

<h1><marquee>&lt;script&gt;document.write(document.cookie);&lt;/script&gt;</marquee></h1><noscript>

obviously your code can be modified to do anything of your liking.
