Descriptions

Cross-Site Request Forgery (CSRF) vulnerability in ThemeHunk Big Store theme <= 1.9.3 versions.

Vulnerabilidad de Cross-Site Request Forgery (CSRF) en el tema ThemeHunk Big Store en versiones <= 1.9.3.

The Big Store plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.9.3. This is due to missing or incorrect nonce validation on the default_home and th_activeplugin functions. This makes it possible for unauthenticated attackers to activate arbitrary plugins via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.
