Multiple SQL injection vulnerabilities in Fiyo CMS 2.0.1.8 allow remote attackers to execute arbitrary SQL commands via the (1) id parameter in an edit action to dapur/index.php; (2) cat, (3) user, or (4) level parameter to dapur/apps/app_article/controller/article_list.php; or (5) email parameter in an email action or (6) username parameter in a user action to dapur/apps/app_user/controller/check_user.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.
