REDCap before 9.3.0 allows time-based SQL injection in the edit calendar event via the cal_id parameter, such as cal_id=55 and sleep(3) to Calendar/calendar_popup_ajax.php. The attacker can obtain a user's login sessionid from the database, and then re-login into REDCap to compromise all data.
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.
