Descriptions

The WP Fastest Cache plugin through 0.8.9.0 for WordPress allows remote attackers to delete arbitrary files because wp_postratings_clear_fastest_cache and rm_folder_recursively in wpFastestCache.php mishandle ../ in an HTTP Referer header.

El plugin WP Fastest Cache hasta la versión 0.8.9.0 para WordPress, permite a los atacantes remotos eliminar archivos arbitrarios debido a las funciones wp_postratings_clear_fastest_cache y rm_folder_recursively en el archivo wpFastestCache.php manejan inapropiadamente ../ en un encabezado Referer HTTP.

WordPress WP Fastest Cache plugin versions 0.8.9.0 and below suffer from an arbitrary file deletion vulnerability.
