Sourcecodester Enrollment System Project V1.0 is vulnerable to SQL Injection (SQLI) attacks, which allow an attacker to manipulate the SQL queries executed by the application. The application fails to properly validate user-supplied input in the username and password fields during the login process, enabling an attacker to inject malicious SQL code.
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.
