College Management System v1.0 - Authenticated remote code execution. An admin user (the authentication can be bypassed using SQL Injection that mentioned in my other report) can upload .php file that contains malicious code via student.php file.
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.
