SQL injection vulnerability in the ENL Newsletter (enl-newsletter) plugin 1.0.1 for WordPress allows remote authenticated administrators to execute arbitrary SQL commands via the id parameter in the enl-add-new page to wp-admin/admin.php.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
