SQL injection vulnerability in ajax.php in evalSMSI 2.1.03 allows remote attackers to execute arbitrary SQL commands via the query parameter in the (1) question action, and possibly the (2) sub_par or (3) num_quest actions.
Improper Neutralization of Special Elements used in an SQL Command 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.
