Descriptions

The WP Super Cache WordPress plugin before 1.7.3 did not properly sanitise its wp_cache_location parameter in its settings, which could lead to a Stored Cross-Site Scripting issue.

El plugin WP Super Cache WordPress versiones anteriores a 1.7.3, no saneababa apropiadamente su parámetro wp_cache_location en su configuración, lo que podría conllevar a no saneababa correctamenteun problema de tipo Cross-Site Scripting almacenados

The Twitter Bootstrap Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wp_cache_location' parameter in versions up to, and including, 1.7.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrative level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
