WordPress Input Validation Holes in Invite Function Permit Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1019564
SecurityTracker URL:  http://securitytracker.com/id/1019564
CVE Reference:   CVE-2008-1304   (Links to External Site)
Updated:  Mar 19 2008
Original Entry Date:  Mar 7 2008
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 2.3.2
Description:   A vulnerability was reported in WordPress. 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 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 WordPress 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 'inviteemail' parameter of the invite function of the 'wp-admin/users.php' script is affected.

The 'to' parameter of the 'wp-admin/invites.php' script is affected.

DoZ from Hackers Center Security Group reported this vulnerability.
