Descriptions

The Blocksy theme for WordPress is vulnerable to Stored Cross-Site Scripting via the className parameter in the About Me block in all versions up to, and including, 2.0.39 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

El tema Blocksy para WordPress es vulnerable a Cross-Site Scripting Almacenado a través del parámetro className en el bloque Acerca de mí en todas las versiones hasta la 2.0.39 incluida debido a una sanitización de entrada y un escape de salida insuficientes. Esto hace posible que atacantes autenticados, con acceso de colaborador y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada.
