[FD] CSRF/XSS in Responsive Poll allows unauthenticated attackers to do almost anything an admin can (WordPress plugin)

Details ================ Software: Responsive Poll Version: 1.6.4,1.7.4 Homepage: http://ift.tt/1lBBtLp Advisory report: http://ift.tt/2j6d0G3 CVE: Awaiting assignment CVSS: 5.8 (Medium; AV:N/AC:M/Au:N/C:P/I:P/A:N) Description ================ CSRF/XSS in Responsive Poll allows unauthenticated attackers to do almost anything an admin can Vulnerability ================ This plugin lacks CSRF checks when updating polls meaning an unauthenticated attacker can cause anything to be modified in a poll. The plugin also fails to escape values put into HTML. The combination of these two means that an unauthenticated attacker can put arbitrary JavaScript into a page in /wp-admin/. Proof of concept ================ Create a poll. We assume that the ID of this poll will be 1. Visit the following page and click submit (in a real attack the form can be submitted without user interaction):

Then visit http://localhost/wp-admin/admin.php?page=polls&action=edit&edit_poll=1 and focus the Question field (either via clicking on it or tabbing to it). Mitigations ================ Disable the plugin until a new version is released that fixes this bug. Disclosure policy ================ dxw believes in responsible disclosure.
