  - An input passed via 'search_string' parameter to the

  - An error in the framework/core/subsystems/expRouter.php script allowing to read database
  information via address/addContentToSearch/id/ and a trailing string.

  - Input passed via 'content_type' and 'subtype' parameter to the
  framework/modules/core/controllers/expRatingController.php script is not validated properly.

  - Insufficient sanitization of input passed via 'selectObjectsBySql' to the
  /framework/modules/ecommerce/controllers/orderController.php script.

  - Insufficient validation of input passed to the
  /framework/modules/core/controllers/expHTMLEditorController.php script.

  - Exponent CMS permits undefined actions to execute by default.

  - Input passed via 'content_id' parameter into showComments within the
  framework/modules/core/controllers/expCommentController.php script is not sanitized properly.");
