| Beschreibung | # Assessment Management System lecturer/marking-scheme.php SQL Injection Vulnerability
A SQL injection vulnerability exists in the `lecturer/marking-scheme.php` file of the Assessment Management System.
The application directly concatenates user-controlled input from the `squestions[]` parameter into an SQL `INSERT`
statement without proper sanitization or parameterized statements. As a result, an attacker can inject arbitrary SQL
syntax into the backend database query.
##
## Impact of the Vulnerability
This vulnerability may allow an attacker to manipulate backend SQL queries, trigger database error-based responses,
and potentially extract sensitive database information. Because the application returns raw database errors via
`mysqli_error($conn)`, successful exploitation can disclose attacker-controlled query output directly in the HTTP
response.
