DESCRIPTION:
Some vulnerabilities have been discovered in the SS Quiz plugin for
WordPress, which can be exploited by malicious people to conduct
cross-site request forgery attacks and bypass certain security
restrictions.

1) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. modify quiz questions and
answers by tricking a logged in administrator into visiting a
malicious web site.

2) An error due to the application not verifying user credentials in
wp-content/plugins/ssquiz/admin-side.php can be exploited to e.g.
modify the quiz templates. 

This can further be exploited to conduct script insertion attacks.

The vulnerabilities are confirmed in version 1.11. Prior versions may
also be affected.

SOLUTION:
Update to version 1.12.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
