Subrion CMS's admin grid sorting helper, gridGetSorting in includes/classes/ia.base.controller.admin.php, whitelists the (ASC/DESC) request parameter via inarray, but falls back to the raw, attacker-supplied GET parameter whenever the requested key is not present in the per-controller whitelist array: , which is then placed into %s with only backtick-quoting and no escaping.

An issue was discovered in Subrion CMS 4.2.1, allowing authenticated adminitrators or moderators with access to the built-in Run SQL Query feature under the SQL Tool admin panel - to gain escalated privileges in the context of the SQL query tool.

Subrion 4.2.1 is vulnerable to Improper Access control because user groups not having access to the Admin panel are able to access it (but not perform actions) if the Guests user group has access to the Admin panel.
