A SQL Injection vulnerability exists in the takeassessment2.php file of CloudClassroom-PHP-Project 1.0. The Q4 POST parameter is not properly sanitized before being used in SQL queries.
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.
