Original Entry Date:  Nov 20 2014
Impact:   Denial of service via network, Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to versions 3.7.5, 3.8.5, 3.9.3, 4.0.1
Description:   Several vulnerabilities were reported in WordPress. A remote user can cause denial of service conditions. A remote user can conduct cross-site scripting attacks. A remote user can conduct cross-site request forgery attacks. A remote user can compromise a target user's account.

Several scripts do not properly filter HTML code from user-supplied input before displaying the input [CVE-2014-9031, CVE-2014-9032, CVE-2014-9035, CVE-2014-9036]. 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 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.

A remote user or a remote authenticated contributor or author can exploit these flaws to compromise the target site.

A remote user can conduct a cross-site request forgery attack to make a target user change their password [CVE-2014-9033].

A remote user can cause denial of service conditions in the checking of passwords [CVE-2014-9034].

A remote user can conduct server-side request forgery attacks when WordPress makes HTTP requests [CVE-2014-9038].

A remote user can exploit a hash collision to access a target user's account if the target user has not logged in since 2008 [CVE-2014-9037].

The links in a password reset email remain valid even if the user remembers their password, logs in, and changes their email address [CVE-2014-9039].

Jon Cave, Robert Chapin, and John Blackbourn of the WordPress security team, Jouko Pynnonen, Javier Nieto Arevalo, Andres Rojas Guerrero, Ben Bidner (vortfu), David Anderson, Bojan Slavkovic of ManageWP, Mo'men Bassel, and Tanoy Bose reported these vulnerabilities.

Impact:   A remote user can cause denial of service conditions.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the WordPress 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 compromise a target user's account.

Solution:   The vendor has issued a fix (3.7.5, 3.8.5, 3.9.3, 4.0.1).

The vendor's advisory is available at:
