Descripción
The Counter live visitors for WooCommerce plugin WordPress is vulnerable to arbitrary file deletion due insufficient path validation in the wcvisitor_get_block function all versions up to, and including, 1.3.6. This makes it possible unauthenticated attackers delete files on server. NOTE: particular vulnerability deletes a targeted directory rather than specified file, which can lead loss of data or denial service condition.
