Version(s): 4.7.2 and prior
Description:   Several vulnerabilities were reported in WordPress. A remote user can conduct cross-site request forgery attacks. A remote user can consume excessive memory on the target system. A remote user can bypass security controls on the target system. A remote user can conduct cross-site scripting attacks.

The software does not properly filter HTML code from user-supplied input before displaying the input. 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.

Media file metadata is affected [CVE-2017-6814]. YouTube embed video URLs are affected [CVE-2017-6817]. Taxonomy term names are affected [CVE-2017-6818].

A remote user can use control characters to bypass redirect URL validation on the target system [CVE-2017-6815].

A remote authenticated administrator can invoke the plugin deletion functionality to delete unintended files [CVE-2017-6816].

A remote user can create a specially crafted HTML page or URL that, when loaded by the target authenticated user, will take actions on the target interface acting as the target user via the Press This component [CVE-2017-6819]. This can be exploited to consume excessive server resources.

Chris Andre Dale, Yorick Koster, Simon P. Briggs, Daniel Chatfield, xuliang, Marc Montpas, Delta, and Sipke Mellema reported these vulnerabilities.

Impact:   A remote user can take actions on the target system acting as the target authenticated user.

A remote user can consume excessive server resources on the target system.

A remote user can bypass redirect URL validation on the target system.

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.

Solution:   The vendor has issued a fix (4.7.3).
