The upsql function in \Lib\Lib\Action\Admin\DataAction.class.php in Gxlcms QY v1.0.0713 allows remote attackers to execute arbitrary SQL statements via the sql parameter. Consequently, an attacker can execute arbitrary PHP code by placing it after a <?php substring, and then using INTO OUTFILE with a .php filename.
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.
