PHPClassifieds Permits Cross-Site Scripting Attacks and Lets Remote Users Inject SQL Commands
SecurityTracker Alert ID:  1016407
SecurityTracker URL:  http://securitytracker.com/id/1016407
CVE Reference:   CVE-2006-3329, CVE-2006-3330   (Links to External Site)
Updated:  Aug 12 2008
Original Entry Date:  Jun 29 2006
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
Exploit Included:  Yes  

Description:   A vulnerability was reported in PHPClassifieds. A remote user can conduct cross-site scripting attacks. A remote user can inject SQL commands.

The software does not properly filter HTML code from user-supplied input when posting a listing before displaying the posted input. A remote user can submit specially crafted text 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 PHPClassifieds 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 'search.php' script does not properly validate user-supplied input in the 'rate' parameter. A remote user can supply a specially crafted parameter value to execute SQL commands on the underlying database.

A demonstration exploit URL is provided:

http://[target]/search.php?rate=[sql]

luny 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 PHPClassifieds 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 execute SQL commands on the underlying database.

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